Orthodontic treatment has changed considerably with the development of removable appliances that can gradually reposition teeth. SureSmile aligners are a type of sequential orthodontic device designed to move teeth progressively according to a customized treatment plan. They are made from clear thermoplastic material and are intended to correct malocclusion under the direction of a dental professional. The U.S. Food and Drug Administration lists SureSmile Aligner as a Class II sequential aligner device.
Unlike traditional braces, aligners can be removed by the patient. However, their effectiveness depends on appropriate case selection, accurate treatment planning, proper wear, and professional monitoring. The American Association of Orthodontists emphasizes that diagnosis should come before selecting an orthodontic appliance because different problems may require different approaches.
What Are SureSmile Aligners?
SureSmile aligners are transparent, removable orthodontic trays designed to move teeth through a planned sequence. According to the FDA’s 2026 device documentation, the aligners apply controlled mechanical forces to progressively reposition teeth toward prescribed target positions. The treatment plan is digitally designed and must be reviewed and approved by the treating clinician before the aligners are produced.
The aligners are provided sequentially rather than as one appliance intended to complete the entire treatment. Each stage represents a planned step in tooth movement.
This makes treatment planning particularly important because the position of each tooth at one stage affects the design and objectives of subsequent stages.
How Do SureSmile Aligners Work?
The process generally begins with an orthodontic or dental consultation. The clinician evaluates the patient’s teeth and oral health and determines whether aligner treatment is appropriate.
Digital scans or other records can then be used to create a three-dimensional representation of the teeth. The treatment software uses this information to plan a sequence of tooth movements.
The FDA describes the process as dividing the planned movement from the initial malocclusion to the desired position into intermediate stages. The clinician reviews and approves the resulting treatment plan before manufacturing.
Patients then progress through the prescribed sequence, with each aligner producing a controlled amount of movement.
Who May Benefit From SureSmile Aligners?
SureSmile aligners may be considered for patients whose orthodontic problems can be appropriately treated with removable aligners.
Potential concerns that orthodontic treatment may address include:
- Crowded teeth
- Spacing between teeth
- Certain bite problems
- Tooth-position irregularities
- Some types of crossbite
- Other forms of malocclusion
However, not every orthodontic problem is equally suitable for aligner treatment.
The American Association of Orthodontists notes that treatment selection depends on the diagnosis and individual circumstances. An orthodontist may recommend aligners for one patient but braces or another approach for someone with a different orthodontic problem.
Are Clear Aligners Suitable for Everyone?
No. Clear aligners are not automatically appropriate for every patient or every type of tooth movement.
Research involving orthodontists has found that clinicians generally report greater confidence using aligners for mild-to-moderate crowding and spacing than for certain more difficult movements. Root movement and extrusion, for example, were identified as more challenging in a survey of orthodontic providers.
Complex skeletal problems, severe malocclusions, impacted teeth, and other conditions may require different or additional orthodontic techniques.
This is why a professional examination is important before deciding which appliance to use.
What Happens Before Treatment Begins?
A comprehensive evaluation is an important first step. The American Association of Orthodontists recommends addressing existing dental needs before beginning aligner treatment because the trays are custom-made to the shape and position of the teeth. Regular dental care should also continue throughout orthodontic treatment.
Depending on the individual case, the evaluation may involve:
- Oral examination
- Dental records
- Digital scanning
- Photographs
- X-rays when indicated
- Bite assessment
- Gum-health evaluation
- Discussion of treatment goals
Healthy gums and teeth are important considerations. The AAO cautions that moving teeth when periodontal health is poor can increase the risk of complications, making appropriate dental evaluation essential.
How Long Does Treatment Take?
Treatment duration varies significantly from one patient to another.
The number of aligners and length of treatment depend on factors such as:
- The starting position of the teeth
- Complexity of the malocclusion
- Planned tooth movements
- Patient compliance
- Biological response
- Whether additional refinement is required
FDA documentation states that SureSmile aligners are provided sequentially over a period of months and are typically replaced every one to two weeks according to the prescribed treatment plan. It also emphasizes that following the prescribed wear schedule is important for achieving the intended tooth movement.
Patients should therefore avoid assuming that another person’s treatment timeline will apply to them.
Why Is Compliance Important?
One of the major differences between removable aligners and fixed braces is that patients are responsible for wearing and caring for the appliance according to professional instructions.
Removing aligners unnecessarily or failing to follow the prescribed schedule can interfere with planned tooth movement.
The FDA specifically identifies compliance with prescribed wear time as critical to achieving the intended movement with SureSmile aligners.
Patients should also follow their clinician’s instructions regarding cleaning, storage, eating, drinking, and changing aligners.
Are Regular Dental Visits Still Necessary?
Yes. Wearing orthodontic aligners does not eliminate the need for professional monitoring.
The AAO recommends regular check-ups during aligner treatment so an orthodontist can determine whether teeth are moving as planned and address problems that arise. Some practices may also use remote monitoring as a supplement to in-person appointments.
Routine dental care remains important as well. Aligners should not be viewed as a substitute for professional cleanings, examinations, or treatment of existing dental problems.
How Do SureSmile Aligners Compare With Braces?
Both aligners and braces are orthodontic appliances, but they work differently.
Traditional braces use brackets attached to the teeth and archwires to apply forces. Aligners use removable trays designed to produce planned tooth movements. The choice depends on the patient’s diagnosis and treatment goals rather than simply which appliance looks more appealing.
The AAO states that no single orthodontic appliance is inherently the right choice for everyone. An accurate diagnosis should guide the treatment plan.
Removability can be convenient for some patients, while fixed braces may provide advantages for certain types of tooth movement.
What Happens After Treatment?
Completing active tooth movement is not necessarily the end of orthodontic care. Teeth can shift after treatment, so retention is generally an important part of maintaining the achieved alignment.
SureSmile’s treatment information includes retainers as part of the post-treatment process.
The type and duration of retention should be determined by the treating dental professional based on the patient’s individual circumstances.
What Should You Ask Before Choosing Aligners?
Before starting treatment, patients can ask their dental professional:
- Is my orthodontic problem suitable for aligners?
- What treatment alternatives are available?
- How long is my estimated treatment plan?
- How often will I need appointments?
- How many hours per day should I wear the aligners?
- What happens if an aligner does not fit properly?
- Will attachments or additional procedures be necessary?
- What retention plan will follow treatment?
- What dental care should I continue during treatment?
- What factors could change the estimated treatment time?
These questions can help patients understand both the benefits and limitations of treatment before making a decision.
Conclusion
SureSmile aligners use digitally planned, sequential trays to gradually move teeth toward prescribed positions. FDA documentation identifies them as orthodontic devices intended for the treatment of malocclusion, with treatment planned and reviewed by a clinician before the aligners are produced. For patients considering clear aligners, an in-person evaluation can help determine whether this approach is appropriate and how it compares with braces or other orthodontic options. The most important factor is a treatment plan based on an accurate diagnosis and continued professional oversight.
