How SureSmile Clear Aligners Work: A Step-by-Step Guide

May 01, 2026

Clear aligners are one option for improving tooth alignment without traditional braces. With SureSmile clear aligners, tooth movement is planned in a series of small stages based on digital records and a clinical assessment.

SureSmile aligners are custom-made trays designed to move teeth gradually according to a personalized plan. Treatment may be suitable for some teens and adults, but not every case is the same. A dental assessment is needed to determine whether aligners are appropriate based on your bite, tooth position, and overall oral health.

Step 1: Initial Consultation & Smile Assessment

Treatment begins with an initial consultation. During this visit, a dentist or prosthodontist examines your teeth, gums, and bite, while also reviewing your dental history and treatment goals.

This appointment helps determine whether aligners may be appropriate for your needs. Some patients with mild to moderate alignment concerns may be candidates for treatment, while others may require a different approach. In cases that involve bite changes, missing teeth, or existing restorations, input from a prosthodontist may also be helpful as part of the overall treatment discussion.

Step 2: Digital Scanning & Imaging

If aligners are being considered, the next step usually involves digital scanning and imaging. These records create a detailed 3D view of your teeth and bite.

This information helps the dental team evaluate spacing, crowding, and how your teeth fit together. Digital scans can also improve the accuracy of treatment planning and remove the need for traditional impressions in many cases.

Step 3: Customized Treatment Plan

Once the scans are complete, a customized treatment plan is created. This plan outlines how your teeth may move over time and how many aligners may be needed.

In some cases, patients may be shown a digital preview of the expected changes. It is important to remember that this preview is a planning tool. It is important to understand that this preview is only an estimate, and treatment progress can vary depending on case complexity and how consistently the aligners are worn. When discussing SureSmile clear aligners in Calgary, AB, the more important question is not speed, but whether the planned movement is appropriate for the patient’s bite and oral condition.

Step 4: Fabrication of Custom Aligners

After the treatment plan is finalized, a series of custom aligners is made. Each set is slightly different and is designed to guide teeth through small, controlled movements.

These aligners are made from clear material and trimmed to fit your teeth closely. The total number of aligners depends on your specific treatment needs and the amount of planned tooth movement.

Step 5: Wearing Your Aligners

Aligners need to be worn as directed for treatment to stay on track. In most cases, aligners are worn for 20 to 22 hours each day and are only taken out for eating, drinking anything besides water, brushing, and flossing.

You will usually change to a new set every one to two weeks, based on your dentist’s instructions. Some people notice mild pressure when they begin wearing a new set. This is often a sign that the aligners are applying force to move the teeth.

Because SureSmile clear aligners are removable, daily wear habits have a direct effect on how closely treatment follows the original plan. Skipping wear time can affect how well the trays fit and may delay progress.

Step 6: Gradual Teeth Movement

Each aligner applies gentle, controlled pressure to specific teeth. Over time, this pressure can move teeth gradually into new positions.

This process depends on the body’s natural response to orthodontic force. The bone and surrounding tissues adapt over time as steady pressure is applied. Tooth movement usually happens in stages, which is why each new aligner is only slightly different from the one before it.

Oral hygiene remains important throughout this stage. Patients should continue brushing and flossing carefully to help reduce the risk of plaque buildup, gum irritation, and tooth decay. In some cases, temporary soreness or pressure may occur, especially when switching to a new aligner.

Step 7: Regular Check-Ups

Regular checkups are scheduled throughout treatment so the dental team can monitor progress and confirm that the aligners are fitting properly.

These visits may also be used to address questions, review eating habits, and determine whether any changes are needed. In many clear aligners in Calgary treatment plans, these follow-up visits are also the best time to confirm whether tooth movement is tracking as expected. Not every visit requires new scans, but ongoing supervision helps support safe and steady progress.

Step 8: Completion & Retainers

Once the final aligners have been completed, your teeth may be close to their planned position. Some patients may need refinement trays if small adjustments are still needed.

After active treatment, retainers are usually recommended. Retainers help maintain tooth alignment and reduce the risk of shifting over time. Your dentist will explain how often they should be worn and how to care for them properly.
