You have been thinking about it for months. Maybe longer. The slightly crowded front teeth. The gap you have been half-hiding in every photograph. The bite that never quite felt right. You have looked at clinic websites, read about Invisalign, wondered whether braces or aligners are better for you, and then closed the tab because it all felt too complicated, too time-consuming, or just too unclear about what actually happens.
This guide is the thing you wished those tabs had given you: a clear, honest, step-by-step explanation of exactly how orthodontic treatment works at Smile Stories, from your first appointment, through the digital scan and treatment plan, to the day you wear your last aligner and collect your retainer.
Three steps. No vague timelines. No glossy promises. Just the honest process, including what each step involves, how long it takes, what your role is, and what happens when something does not track exactly as planned.
- Steps from the first scan to your final smile at Smile Stories
- Daily wear is required for aligners to work on schedule
- Time until visible changes begin, per AAO (American Association of Orthodontists)
- How long you should wear your retainer, the step people skip and regret
Why Understanding the Process Before You Start Matters
Orthodontic treatment is a partnership. The clinical outcome, the final position and alignment of your teeth, depends on the precision of the planning and the consistency of your participation throughout treatment. A patient who understands what each step requires, why it matters, and what “not doing it correctly” leads to is significantly more likely to complete treatment successfully, on time, and with the result they were shown in the original simulation.
The most common reasons aligner treatments take longer than planned or deliver results below the initial simulation come down to three things: inadequate pre-treatment diagnosis (cases that were not properly assessed at Step 1), treatment plans that were not accurately tailored to the specific tooth movements needed (Step 2), and inconsistent aligner wear (Step 3). Understanding all three steps and your role in each gives you the clinical context to be an active participant rather than a passive recipient of treatment.
Step 1: Scan & Diagnose Your first appointment:
Building the complete clinical picture of your teeth, bite, and facial profile.
Every successful orthodontic outcome begins with a complete, accurate diagnosis. The quality of what goes into Step 1 directly determines the quality of the treatment plan created in Step 2, and therefore the quality of the final result. At Smile Stories, the first appointment is never a cursory glance and a quick sales pitch. It is a structured diagnostic session with a specific clinical purpose.
Clinical Examination will happen for your teeth and gums,s clinically, checking for cavities, existing restorations, gum health, and any conditions that would need to be treated before orthodontics begins. A tooth with an untreated cavity cannot be safely moved with an aligner; any underlying dental health issues are identified and planned for at this stage. Your bite (how your upper and lower teeth meet) and jaw relationship are assessed, and any symptoms of jaw joint (TMJ) concerns are noted.
- Intraoral and Facial Photographs: A standardised set of photographs is taken, including close-up views of the teeth from the front and sides, and full-face photographs from the front and profile. These serve two clinical purposes: they capture the baseline your treatment is starting from (invaluable for comparing progress), and they contribute to the facial profile analysis that ensures the final tooth position looks natural within your face, not just clinically correct in isolation.
- Diagnostic X-Rays (OPG and/or Cephalometric): An OPG (panoramic X-ray) image all the teeth, roots, and surrounding bone, revealing root lengths, bone levels, the presence of all teeth (including unerupted teeth in younger patients), and any pathology that affects the treatment plan. For cases involving significant bite correction, a cephalometric (lateral skull) X-ray is taken to analyse the relationship between the teeth, jaw bones, and facial skeleton, essential for planning jaw position changes that go beyond simple tooth alignment.
- Digital Intraoral Scan: The Replacement for Impressions. This is the step that patients consistently find more comfortable than expected. A small, lightweight digital scanner wand is passed over your upper and lower teeth, capturing thousands of data points per second to build a precise 3D digital model of every tooth surface, gum contour, and bite relationship, in real time, displayed on screen as the scan progresses. The entire scan takes 3–5 minutes. There are no impression trays, no putty material to hold in your mouth, no gagging risk, and no messy cleanup. The digital model produced is demonstrably more accurate than traditional PVS (physical) impressions for aligner fabrication, particularly for capturing fine tooth surface detail and interproximal spaces.
- Diagnosis and Candidacy Assessment: With all records in hand, the smile stories team of dentists formulates a diagnosis: the specific type and severity of misalignment (crowding, spacing, overbite, underbite, crossbite, rotation, open bite, or combinations), the jaw relationship, gum and bone health status, and your candidacy for different orthodontic options. Not every case is best suited to aligners; some bite discrepancies, skeletal relationships, or tooth movement requirements are handled more predictably with fixed braces. At this stage, the right option for your specific case is identified and explained with clinical reasoning.
Duration of Step 1 Appointment
- What You Leave With: Clinical diagnosis, candidacy assessment, and a clear explanation of your options
- What We Need From You: Any previous dental records, current medication list, and our smile goals
- Between Step 1 and Step 2: Any pre-treatment dental work (fillings, scaling, extractions if needed) is completed.
Pre-treatment dental health first: Before any orthodontic treatment begins, all active dental disease must be treated. Cavities are filled. Gum disease is brought under control. This is not bureaucracy; moving teeth through inflamed or infected gum and bone compromises both the orthodontic result and the underlying bone health. At Smile Stories, the sequence is always: dental health first, then orthodontics.
Step 2: Plan & Preview Your treatment simulation:
Seeing your final smile before the first aligner is made and approving every planned tooth movement
Step 2 is what makes modern aligner treatment categorically different from orthodontics even a decade ago. Using your digital scan and diagnostic records, a stage-by-stage 3D animation of your planned treatment is produced, showing exactly which teeth move in which direction, how far, and in which sequence, ending with the final predicted position of every tooth in your mouth. You watch this animation, discuss any adjustments to the planned final result, and give your approval before a single aligner is manufactured. This is not marketing. It is a clinical and procedural reality. The treatment simulation is the governing document for the entire treatment; every aligner in your series is fabricated to enact the exact movements shown in the simulation you approved. If you see something in the simulation that does not match what you want (a tooth not moving far enough, a midline that remains off-centre, a result that does not match your stated smile goals), it is changed at Step 2, not after six months of wearing the wrong aligners.
Treatment Goal Setting: Your records are uploaded to the treatment planning software alongside your clinical goals: the specific alignment issues to address, the bite correction targets, and any aesthetic goals (midline correction, incisal edge position, arch widening). The Smile Stories team of dentist translates these into precise 3D tooth movement prescriptions, specifying for each tooth the exact amount of rotation, tipping, bodily movement, extrusion, or intrusion required to achieve the target position.
- 3D Treatment Simulation: The planning software, using your digital scan as its starting point, calculates the optimal sequence of tooth movements to achieve the prescribed final positions, generating a series of intermediate digital models (each representing one aligner stage). The result is a stage-by-stage animation: you see your teeth at Stage 1, Stage 5, Stage 12, and the final stage with full 3D rotation capability so you can examine the predicted result from every angle. This simulation is reviewed and refined until the planned outcome matches your goals.
- Patient Review and Approval: You sit with the dentist and review the simulation together on screen. This is a genuine discussion, not a tick-box. You point to any tooth that doesn’t appear to move as far as you expected. You discuss the planned bite correction. You ask about the midline. Any adjustments to the treatment plan are made at this point. When you are satisfied with the planned outcome, you approve the simulation, and it is submitted for aligner fabrication.
- Aligner Fabrication: The approved simulation translates into a complete series of custom clear plastic aligner trays, each manufactured using 3D-printed models of each intermediate tooth position and thermoformed with medical-grade, BPA-free clear thermoplastic material. Each aligner is designed to move the teeth a precise, small amount from the previous stage, typically 0.2–0.3mm per aligner per tooth. A full treatment series may comprise 10 aligners (for a mild case) to 40+ aligners (for a comprehensive case). The complete series is fabricated before treatment begins, so you always have your aligners ready to advance.
Time Between Step 1 and Step 2: 1–2 weeks (planning + fabrication time)
- Duration of Step 2 Appointment: 30–60 minutes (simulation review)
- Time to Receive Aligners After Approval” 2–4 weeks (laboratory fabrication)
The simulation is predictive, not guaranteed: The 3D simulation shows the planned final result assuming your teeth respond as expected to the planned forces. In practice, individual biological variation, how quickly bone remodels around moving teeth, and whether you wear the aligners consistently, affect how closely the outcome matches the simulation. This is why monitoring appointments and the refinement process in Step 3 exist. The simulation is an excellent guide, not a contract.
Step 3: Wear, Monitor & Retain The active treatment phase:
Progressive aligner sets, regular monitoring, and the retainer that holds your result for life
Step 3 is where your teeth actually move. It is also the longest step, spanning your full treatment duration, and the step that depends most on your active participation. Everything in Steps 1 and 2 was the clinic’s work. Step 3 is a shared responsibility: the aligners and the monitoring appointments are the clinic’s contribution; consistently wearing them for the right number of hours every day is yours. The Active Treatment Phase: What You Do Daily
First Aligner Delivery and Attachment Bonding: Your first aligner appointment includes the bonding of attachments where required. Attachments are small, tooth-coloured resin bumps bonded to specific tooth surfaces. They give the aligner material a grip point for movements that require more precise force than a smooth aligner surface alone can generate (rotations, extrusion of specific teeth, torque corrections). They are invisible at conversational distance and are removed at the end of treatment. Not every case needs attachments; your simulation will show where they are placed. Your first aligner is fitted, and you are shown how to insert, remove, and care for it.
- 20–22 Hours/Day Wear: Non-Negotiable Aligners move teeth through sustained, gentle force. They can only apply that force when they are in your mouth. The clinical standard for aligner treatment is 20–22 hours per day, removed only for eating, drinking anything except water, and brushing. This leaves 2–4 hours per day for meals. For most adults, this is entirely manageable. But it is the commitment that aligner treatment requires, and it is honest to say that patients who wear their aligners for 18 hours instead of 22 will either have a longer treatment timeline or a result that does not fully match the simulation.
- Advancing Through Aligner Sets: You advance from one aligner set to the next approximately every 1–2 weeks; the exact timing is specified in your treatment plan. Each new aligner fits slightly differently from the previous one, applying force in a new direction to continue the progression toward the planned final position. New aligners typically feel tight for the first 24–48 hours; this is normal and indicates that tooth movement is occurring. If an aligner feels completely loose and comfortable immediately upon insertion, it may indicate the previous stage has not been worn long enough for the teeth to have moved into the required position.
- Regular Monitoring Appointments (Every 6–8 Weeks): At each monitoring appointment, Dr Srmriti Bharti compares your current tooth positions against the planned positions in your digital simulation. This involves fitting the next few aligners over the current teeth to visually assess whether they seat correctly. A tight, complete fit indicates the teeth are tracking as planned. An aligner that leaves visible gaps between the tray and the teeth indicates a tracking discrepancy; that specific tooth has not moved as far as the plan predicted. Tracking discrepancies caught early are corrected with a refinement; caught late, they require a more significant intervention.
- Interproximal Reduction (IPR), If Required: Some treatment plans require IPR, the controlled polishing of very small amounts of enamel from between specific adjacent teeth, using flexible abrasive strips. IPR creates a fraction of a millimetre of additional space that allows teeth to rotate or align into the planned position without requiring an extraction. It is painless (enamel is not innervated), takes only a few minutes at the specific appointment where it is scheduled, and the amounts involved are carefully controlled (typically 0.1–0.3mm per contact). Whether IPR is part of your plan is shown in the Step 2 simulation.
- Refinements, The Normal, Expected Mid-Treatment Correction: Refinements are new scans and a new aligner series produced when the teeth’s actual positions at a given point in treatment do not exactly match the positions predicted by the simulation. They are a normal, expected part of comprehensive aligner treatment, not a sign that treatment has failed. The American Association of Orthodontists and aligner system literature consistently note that most comprehensive aligner cases require at least one refinement. A refinement captures the current actual tooth positions, recalculates the remaining movements needed to reach the original target, and produces a new set of aligners to complete the treatment. Refinements are included in a comprehensive treatment plan at Smile Stories.
The Retention Phase: The Step You Cannot Skip
Treatment does not end with your last aligner. This is perhaps the most important thing to understand about orthodontics, whether with aligners or braces. When teeth have been moved to their new positions, the bone and ligament fibres that hold them in place have been stretched and compressed into new configurations. Those fibres have elastic memory; they will pull the teeth back toward their original positions if the teeth are not held in place while the bone and fibres reorganise around the new position. This reorganisation takes months to years. The retainer is what holds the teeth in position during this period.
- Retainer Fitting: Your Last Appointment Before Maintenance. At the final treatment appointment, a new digital scan is taken of your completed smile. This scan produces a custom retainer, typically a clear Essix-style retainer (similar in appearance to an aligner but fabricated from denser, more durable material) that fits snugly over the teeth in their final position. For some patients, particularly those with rotations or spacing that historically tended to relapse, a fixed bonded retainer (a thin wire bonded to the back surfaces of the front teeth) provides additional security alongside the removable retainer.
- Retainer Wear Schedule: What “For Life” Actually Means The retainer wear schedule typically progresses: full-time (20–22 hours/day) for the first 3–6 months after treatment completion, then nights-only for the following 6–12 months, then nights-only indefinitely. The “indefinitely” part is not a marketing overstatement; teeth are biologically dynamic throughout life, and some degree of drift is a normal ageing process. Patients who wear their retainers long-term maintain their treatment result indefinitely. Patients who stop wearing their retainer within 1–2 years of completing treatment almost universally experience some degree of relapse, typically greatest in the crowding areas that were most challenging to treat.
Necessary Steps:
- Monitoring appointment frequency
- Every 6–8 weeks during active treatment
- Aligner change frequency
- Every 1–2 weeks (as specified in your plan)
- Required daily wear time
- 20–22 hours non-negotiable for on-schedule results
- Retention phase begins
- Immediately after the final aligner, no gap in wear time
Treatment Timeline: How long Will Your Case Take?
Treatment duration is one of the first questions patients ask, and one of the hardest to answer without seeing an X-ray and performing a clinical assessment. But the following general framework applies to the majority of adult cases:
Mild Cases: Crowding or Spacing up to 4mm. Estimated duration: 3–6 months. Typically, 15–25 aligner stages. Examples: minor front tooth crowding, small diastema (gap between upper front teeth), minor rotations. These cases often resolve quickly and with minimal complexity, though a retainer is still essential afterwards. Patients frequently see visible improvement within the first 4–6 weeks.
Moderate Cases: Crowding or Spacing 4–6mm with Minor Bite Involvement. Estimated duration: 6–12 months. Typically, 25–40 aligner stages. Examples: moderate crowding requiring IPR for space, multiple rotations, minor overbite correction alongside alignment, and midline correction. One refinement is common and expected. Results are visible to others within 2–3 months.
Complex Cases: Significant Crowding, Spacing, or Bite Discrepancy. Estimated duration: 12–18+ months. Examples: significant crowding requiring extraction or significant IPR, overbite/underbite correction, open bite treatment, crossbite correction, and cases involving jaw position changes. Fixed braces may be recommended alongside or instead of aligners for complex bite correction. One or more refinements are expected.
Teen and Adolescent Cases: Duration varies by case complexity. Teenagers are excellent aligner candidates; their bone is more responsive to tooth movement forces, meaning results can often be achieved faster than in adults. Cases involving active growth (under 16) require growth consideration in the treatment plan. Compliance tracking features in teen-specific aligner systems help parents and clinicians monitor wear time.
Aligners vs Braces: Which Is Right for You?
Clear aligners are not the best choice for every case. At Smile Stories, we offer metal braces, ceramic braces, and clear aligners, and the recommendation is always based on what will produce the best clinical outcome for your specific misalignment, not on which option generates the most revenue or appeal.
- Clear Aligners: Custom-fabricated removable clear trays: Nearly invisible in daily life. Removable for eating, drinking, sports, and special occasions. Requires strict compliance (20–22 hrs/day). Ideal for adults and motivated teens who want discretion and the flexibility of a removable appliance. Best for: Mild to moderate crowding, spacing, rotations, minor bite correction, and adult patients with lifestyle flexibility requirements. Best for most adults
- Metal Braces Fixed stainless steel brackets and wires bonded to the teeth: Always working, 24 hours a day, 7 days a week. No compliance requirement beyond brushing. The highest-precision tool for complex tooth movement, particularly torque control and vertical movements. Recommended for complex cases and children/teens where compliance with removable appliances is a concern. Best for: Complex cases, significant bite correction, patients who may struggle with aligner compliance, children and teens. Most cost-effective
- Ceramic Braces Fixed braces using tooth-coloured ceramic brackets instead of metal: Significantly less visible than metal braces, but maintaining the precision of fixed mechanics. Slightly more expensive than metal braces and slightly less stain-resistant than metal, but an excellent middle-ground for adults who need fixed braces but prefer minimal aesthetic impact. Best for: Adults who need fixed braces precision but prioritise aesthetic discretion over the flexibility of aligners.Discrete fixed option
- Kids’ Braces Age-appropriate orthodontic correction for children: from early interceptive treatment (to guide jaw development) through standard braces for alignment of permanent teeth. Growth-guided planning is critical at this stage: the timing of treatment relative to jaw development significantly affects the result achievable without surgical intervention later. Best for: Children with early crowding, crossbites, developing bite discrepancies, or habit-related alignment issues. For young patients
The honest comparison (per published AAO data): Clear aligners and braces produce equivalent outcomes for mild to moderate cases in motivated patients. For complex bite correction cases, fixed braces provide greater precision and predictability. For patients who struggle with wearing removable appliances consistently, fixed braces always work; aligners only work when worn.
Am I a Good Candidate for Clear Aligners at Smile Stories?
- You Are Likely a Good Aligner Candidate If: Your crowding, spacing, or bite issue is mild to moderate in severity You can commit to wearing the aligners 20–22 hours per day consistently You have good oral hygiene habits, aligners require diligent brushing after meals before reinsertion You are an adult or a motivated, compliant teenager with parental support Your gum and bone health are good (or will be after pre-treatment management) You value discretion and the ability to remove the appliance for special occasions or sports Your case does not require extractions (most non-extraction cases are aligner-suitable)
- Fixed Braces May Be Better Suited If: Your case involves significant bite correction (severe overbite, underbite, or skeletal discrepancy) Multiple teeth require significant vertical movement (extrusion or intrusion) You have a history of poor appliance compliance with previous orthodontic treatment You are a child still in active jaw growth phase Your case requires specific torque control that is more predictable with fixed mechanics Your lifestyle or work involves frequent situations where removable appliances are impractical Cost is the primary decision factor, metal braces are typically more affordable than comprehensive aligner treatment
Making the Most of Your Aligner Treatment: Compliance Tips That Actually Matter
- Track Your Wear Time: Use the timer on your phone or a dedicated app to track the hours you spend with aligners out. The 2–4 hours of total removal time per day get used up faster than most patients realise, particularly if you have multiple meals plus brushing time. Awareness prevents underwear without you realising it.
- Always Brush Before Reinsertion: Inserting aligners over unbrushed teeth after a meal traps food particles and bacteria against tooth surfaces, dramatically increasing cavity risk under the aligner. The habit is simple: eat, brush, reinsert. Every time, without exception. A travel toothbrush kit for the office and car makes this practical.
- Water Only While Wearing: Any coloured or sugary drink consumed while wearing aligners bathes every tooth surface in that liquid at an amplified concentration, a fast route to staining both the aligners and the enamel. Coffee, tea, cold drinks, and juice must all be consumed without aligners in. Hot drinks can also warp the thermoplastic material.
- Never Sleep Without Your Aligners: Sleeping without your aligners removes 7–8 hours of the most productive wear time available, because you are not eating or drinking during sleep. Missing even three nights per fortnight significantly reduces effective daily wear time. Establish the habit of inserting your aligner immediately before you get into bed.
- Always Use Your Case When Aligners Are Out: The most common reason patients lose their aligners is wrapping them in a napkin at a restaurant and accidentally throwing them away, or leaving them on a table and having a pet investigate. A rigid carry case costs less than a replacement aligner set. Use it every time, without exception.
- Never Skip Monitoring Appointments: The 6–8 weekly check appointments are not optional social calls; they are the mechanism by which tracking discrepancies are caught before they compound. A tracking issue caught at Week 6 takes a small refinement to correct. The same tracking issue caught at Week 18 may require the entire remaining treatment series to be remade. Attend every appointment scheduled.
What’s included in Smile Stories’ aligner treatment fees: Clinical consultations throughout treatment, all aligner sets for the planned duration, monitoring appointments (every 6–8 weeks), attachment bonding and removal, IPR where planned, and one refinement series if clinically required. Diagnostic records (scan, X-rays, photographs) are quoted separately at the initial assessment appointment. Post-treatment retainers are quoted separately.
