Braces or aligners is a case-selection question first
Parents usually arrive with the appliance question already framed: metal or clear. A provider should reframe it before answering, because the first question is what the case needs.
A systematic review of the clinical effectiveness of Invisalign treatment concluded that aligners are a viable option for mild to moderate non-extraction cases in adults, with limited efficacy where large discrepancies have to be corrected. Aligner systems and protocols have developed since, and providers do treat a wider range of cases, but the underlying principle holds: some tooth movements are more predictable with fixed appliances, and a complex case is where that difference shows.
What you want to hear is a provider who says which movements your teen's case requires, which appliance handles those movements more predictably, and where the two options are genuinely equivalent so that preference can decide. What you do not want is an appliance recommended before the case is described.
Our guide to braces compared with aligners sets out the provider and case-selection questions in more detail, and how Invisalign provider designations work explains what those designations do and do not tell you.
The 20 hour standard and how a provider assesses compliance
Clear aligners are removable, which is the advantage and the risk in the same sentence. The wear standard is 20 or more hours per day, every day, for the length of treatment. Aligners come out to eat and to brush, and go back in immediately afterwards.
That is a real demand on a fourteen-year-old with a busy schedule. Lunch at school, a snack after practice, a sleepover, a forgotten case at a friend's house: each of these is a small loss of wear time, and enough of them together means the teeth stop tracking the plan. The usual consequences are extra appointments, revised aligners and a longer overall timeline.
A provider who takes this seriously will raise it before you do. Look for a conversation that covers how wear will be tracked, what happens when tracking slips, whether the practice uses compliance indicators, and at what point the plan would be changed to fixed appliances instead. Fixed braces remove the cooperation variable for tooth movement, at the cost of visibility and a more involved cleaning routine. Neither choice is a character judgement about your teen. It is a practical assessment, and it should be made openly with your teen in the room.
Growth modification while your teen is still growing
Where a teenager's lower jaw sits back relative to the upper, and growth remains, there may be an opportunity to influence the relationship between the jaws rather than only compensating for it with tooth movement.
The options a provider may propose include twin blocks and similar functional appliances, which hold the lower jaw in a forward posture, and Invisalign with mandibular advancement, which combines aligner tooth movement with the same forward positioning. Both depend on wear, and both work with growth that is still available.
This is why timing questions are worth asking directly. Ask how your teen's growth status was assessed, how much growth the provider expects remains, and what changes about the options once growth is complete. Where growth has finished and the discrepancy is significant, the conversation shifts to camouflage treatment or a surgical plan, which we cover in when jaw surgery is discussed.
The Cochrane review of treatment for prominent upper front teeth in children and adolescents is the reference point here, and it supports treatment in adolescence rather than urging that it be brought forward. The practical implication for a teenager is that there is usually a window rather than a deadline, and it is reasonable to ask where in that window your teen currently sits.
School, sport and music: logistics worth asking about
Treatment runs for a year or more through school terms, sports seasons and everything else your teen does. These questions belong in the consultation, not in the first month of treatment.
- Appointments. How often are visits, how long are they, and can any be scheduled outside school hours?
- Contact sport. What mouthguard arrangement does the provider recommend over fixed appliances, and when should it be replaced? The Canadian Dental Association's position on sport mouthguards is a useful background read.
- Wind instruments. Players of brass and woodwind instruments usually adapt, but the adjustment period is real. Ask whether the provider has worked with student musicians and what they advise.
- Food and cleaning. With fixed appliances there is a list of foods to avoid and a longer cleaning routine. With aligners there is no food list, but there is the discipline of removing and replacing them.
- Photos and events. Teens ask about this, and it is a reasonable thing to ask about.
For the lived detail of what these months feel like day to day, our treatment-experience sibling site covers it directly at surreybraces.com. This guide stays on the choice of provider; that site covers the experience of treatment itself.
Emergencies and access between appointments
Something will come loose at an inconvenient moment. A bracket detaches the night before a trip, a wire slides and catches the cheek, an aligner is lost the day a new set was due to start. How a practice handles that is part of what you are choosing.
Ask how urgent problems are triaged, who answers when the practice is closed, whether advice is given by phone or message before an appointment is offered, and how quickly a loose bracket or a poking wire is typically seen. Ask also what a lost aligner means in practice: which set to wear, how to report it, and whether replacements involve a wait.
If the practice has more than one clinician, ask who your teen will actually see at routine visits, and who manages the case overall. Continuity is not essential in every appointment, but knowing the arrangement in advance prevents a misunderstanding later.
Bringing your teen into the decision
A teenager who has agreed to treatment behaves differently from one who has been signed up for it, and with a removable appliance that difference is the whole plan.
Useful signs at a consultation: the clinician addresses your teen directly and waits for answers; your teen is asked what bothers them about their teeth rather than only being told what is wrong; the wear requirement is explained to your teen as a commitment, not mentioned to you over their head; and your teen is given room to ask something without being spoken over.
It is also worth giving your teen a say in the appliance decision where the case genuinely allows both options. Where it does not, the reason should be explained to them rather than announced. A teen who understands why fixed appliances were selected is better placed to stay with the plan than one who was simply told.
Comparing quotes between two practices
Two written plans are the only fair basis for comparison, and quotes are rarely comparable until you check what each one covers.
Ask each practice to confirm in writing what is included and what is not. The items that most often differ are the records and diagnostic appointment, the appliances themselves, routine adjustment visits, emergency visits, any refinement aligners, retainers at the end of treatment, replacement retainers, and review appointments after treatment finishes.
Then check that the two plans are actually describing the same treatment. A shorter plan may be treating a different diagnosis, planning fewer movements, or assuming a level of cooperation that has not been discussed. Comparing the diagnosis first and the numbers second is the way to avoid choosing a plan on a difference that was never like for like.
Our guides to comparing orthodontic quotes and what a quote should include set out the line items to check. Retention belongs in that list: ask which retention protocol each practice uses and why, since long-term retention is what holds the result.
Questions readers ask
Can a teenager have Invisalign instead of braces?
Often, but it depends on the case and on wear. A systematic review found aligners viable for mild to moderate non-extraction cases and of limited efficacy for large discrepancies, and the practical requirement is 20 or more hours of wear per day. Ask the provider which movements your teen's case requires and whether both options handle them predictably.
What happens if my teen does not wear the aligners enough?
The teeth stop tracking the planned movements. In practice that means extra appointments, revised or additional aligners, and a longer overall timeline. A good practice tracks wear, raises the issue early, and has a stated point at which it would recommend switching to fixed appliances instead.
Can my teen play contact sport with braces?
Yes, with a mouthguard suited to fixed appliances. Ask the provider what arrangement they recommend, how it should be fitted over brackets, and how often it should be replaced as treatment progresses. The Canadian Dental Association's position statement on sport mouthguards is a useful background read for parents.
Is my teen too old for growth modification?
It depends on remaining growth rather than birthday, and growth generally completes earlier in females than in males. Ask how growth status was assessed and how much growth the provider expects remains. Where growth has finished and the discrepancy is significant, the conversation shifts to camouflage treatment or a surgical plan.
Two practices quoted different amounts. How do I compare them?
Compare the diagnosis first. A shorter or cheaper plan may be treating a different problem or assuming cooperation that has not been discussed. Then compare inclusions line by line: records, appliances, adjustments, emergency visits, refinements, retainers, replacement retainers and post-treatment reviews. Get both in writing before deciding.
