Straightening your teeth without brackets and wires sounds simple — and for the right person, clear aligners are a genuinely convenient way to do it. But “the right person” is doing real work in that sentence. Clear aligners can correct a lot of common alignment problems, and there are some they honestly can’t — and the difference isn’t about how much you want them. It’s about your bite, how far your teeth need to move, the health of your gums, and whether the daily wear the treatment requires is realistic for you — or for your teenager.
This guide is a self-screening tool: a clear aligner candidate in North York checklist covering the problems aligners handle well, the cases that usually need braces or other treatment first, and what an assessment at Vita Dentistry checks before anyone says yes or no. It won’t qualify or disqualify you — only an in-person assessment can do that — but it will tell you what the honest questions are, so you can walk in already knowing them.

What “Candidacy” Actually Means for Clear Aligners
Clear aligners are a series of custom-made, removable transparent trays. You wear each set for a planned period — often one to two weeks — and each set moves your teeth a small amount, step by step, toward the final position in your treatment plan. If you’d like the full picture of how the treatment itself works, start with our page on clear aligner treatment in North York; this guide focuses on the question that comes first: whether aligners fit your teeth, your bite and your life.
“Candidacy” is a clinical judgement, and it has three parts. First, the mechanics: can trays — which grip the teeth and push them along planned paths — produce the movements your case needs? Second, the foundation: are your teeth and gums healthy enough to move safely? Third, the human part: aligners only work while they’re in your mouth, so candidacy also depends on whether the wear schedule the treatment needs is realistic for you. A “yes” needs all three.
The Crowding and Bite Problems Aligners Handle Well
Clear aligners are at their best with mild to moderate problems, including:
- Mild to moderate crowding — teeth that overlap or sit slightly rotated because there isn’t quite enough room.
- Gaps and spacing — spaces between teeth that can be closed by moving teeth together.
- Some bite problems — many overbites, and some underbites and crossbites, can be improved when the problem is mainly in how the teeth meet rather than in the size or position of the jaws themselves.
- Relapse after braces — teeth that have drifted since earlier orthodontic treatment are often good candidates, because the movements needed are usually small.
Many plans also use small tooth-coloured attachments bonded to some teeth, which give the trays something to grip for trickier movements. Their presence doesn’t mean your case is severe — they’re a normal part of many straightforward plans. Once treatment starts, the day-to-day questions — eating, cleaning, tray changes, speaking with them in — are covered in our post on what living with aligners is actually like; this guide stays on the question before all of that: should you start?
Cases That Usually Need Braces — or Treatment First
Being told aligners aren’t the right tool is not a sales tactic in either direction — some movements are simply beyond what a removable tray can do reliably:
- Severe crowding, or teeth that need to be removed to make room — cases where controlled, anchored movement matters most.
- Bite problems rooted in the jaws — a large mismatch between upper and lower jaw size or position is skeletal, and trays move teeth, not jaws. These cases may need braces, other appliances, or a specialist orthodontist’s care.
- Movements trays do poorly — large rotations of rounded teeth such as canines and premolars, teeth that need to be pulled down into line, or teeth that must be uprighted from a strong tilt.
- Complex mouths — several missing teeth, or bridges and implants that can’t move (an implant is fused to the bone and stays where it is; aligners can move the teeth around it, not the implant itself).
- Active dental disease — untreated cavities or gum disease must be treated before any orthodontic movement. Moving teeth through inflamed gums can make gum problems worse, so the honest order is: get healthy first, then straighten.
Sometimes the right answer is a combined plan — braces for the hard movements, for example, or treatment in stages. And sometimes it’s a referral: Vita’s dentists are general dentists, and if your case is better handled by a specialist orthodontist, we’ll tell you that plainly.
Teens and Aligners: Maturity Matters More Than Age
Parents ask about teens more than about any other group, and the honest answer is that age is the least important part of the decision. Two things matter:
- Growth and teeth. A teen needs most of their permanent teeth in place before a plan is built, and a still-growing jaw changes the planning — the assessment looks at both.
- The wear discipline. Aligners work 20 to 22 hours a day, every day — through school, sports, part-time jobs and everything else. Some teens are excellent at it: trays in, case in the pocket, routine kept. Others honestly aren’t yet, and for them there’s no shame in it — but there is a consequence: trays that live in a locker don’t move teeth, and the treatment stalls while the calendar runs.
For a teen who isn’t ready for that discipline, braces remove the daily decision entirely, which protects both the result and the family’s money. “Braces now, aligners later if wanted” is a good answer, not a failed one — and saying so at the assessment is part of giving you an honest one.
Health and Habit Factors: Gum Health, Wear-Time Honesty and Smoking
Three factors outside your bite diagram decide a lot of candidacy assessments:
- Gum health. Your gums and the bone under them are the foundation every tooth movement stands on. Healthy gums and good day-to-day cleaning are prerequisites, not extras.
- Wear-time honesty. Aligners are typically worn 20 to 22 hours a day — removed for meals, for drinks other than water, and for brushing and flossing. That number is the treatment. Wearing trays only at night, or “most days”, stretches the plan out, lets teeth drift back between wears, and is the most common reason aligner treatment disappoints. If 20–22 hours honestly doesn’t fit your life right now, that’s a real candidacy answer — and it’s better learned before treatment than during it.
- Smoking and vaping. Smoking affects gum health and healing, and trays worn over smoking breaks pick up staining and odour. It’s part of the assessment conversation, not a footnote.
None of these are character judgements. They’re the same factors your dentist will weigh, and naming them here lets you walk into an assessment already knowing the discussion.
What the Assessment at Vita Dentistry Checks
An aligner assessment at Vita Dentistry is an examination, not a commitment. It typically includes:
- A look at your teeth and bite — how they meet, where the crowding or spacing is, and how much movement each tooth would need.
- The health check: gums, existing fillings and crowns, any cavities or wear that should be dealt with first.
- Records such as X-rays and images or scans of your teeth, so movement can be planned against your actual roots and bone, not just the visible crowns.
- The lifestyle conversation — wear time, work and school routines, and whether the discipline of the treatment fits.
From that, your dentist can say whether aligners are a sensible option for you, whether something else should come first, or whether braces or a specialist referral would serve you better. If aligners are recommended, you’ll see what the plan involves — including how long it’s expected to take and what it costs — before you decide anything.
Clear Aligners vs Braces — an Honest Comparison
Neither option is “better” in general; they’re better at different things. Braces are fixed to the teeth, so they work around the clock without depending on memory or willpower, and they can deliver the more difficult movements listed above. Aligners are removable and hard to see, eating and brushing are simpler because the trays come out, and there are no brackets to catch on your cheeks — but they only work while worn, and some movements are slower or less predictable with trays.
For a straightforward case in a disciplined adult, aligners are often the simpler experience. For a complex bite, a teenager still growing, or anyone who knows a removable appliance will spend too much time in its case, braces may honestly be the stronger plan. Our page on when braces are the better plan explains the braces side in full.
A Note on Brand Names — Why We Say “Clear Aligners”
You may well have started your search using a brand name — a lot of patients do, because one well-known name has become shorthand for the whole category, the way people use a single word for tissues or adhesive bandages. We use the plain description “clear aligners” on purpose: it names the treatment itself, not a label. What matters for your result is the assessment, the plan, and whether you wear the trays as directed — and those are the things we’ll discuss with you, whatever words you arrived with. One of the questions in the FAQ below takes up the brand question directly, because patients ask it directly.
What Happens If You’re Not a Candidate Yet
“Not yet” is the most common version of “no”, and it usually comes with a path: treat the gum disease or cavities first and reassess; handle the one movement aligners can’t do, then reconsider; or choose braces for this round of treatment and keep the result with a retainer afterwards. What you won’t get from us is aligners sold to a case they can’t fix — a failed aligner plan costs you the same months a correct plan would have, with nothing to show for them.
And whichever way the assessment goes, one commitment applies to every successful straightening, with aligners or braces: retainers afterwards. Teeth keep a memory of where they used to sit, and without retainers they drift back — sometimes within months. If you straighten your teeth, plan on wearing retainers as directed for as long as you want the result to last, which in practice means ongoing night-time wear.

Frequently Asked Questions About Clear Aligner Candidacy
Can clear aligners fix an overbite or gaps?
Often, yes — within limits. Gaps and spacing are among the problems aligners handle best, because closing a space is a movement trays do predictably. Overbites depend on their cause: many are driven mainly by the angle and position of the teeth, and aligners can improve those cases by moving the teeth into a better relationship. An overbite that comes from the jaws themselves — a lower jaw that sits well behind the upper — is a skeletal problem, and trays cannot change jaw size or position; those cases may need braces, other appliances, or a specialist orthodontist. Your assessment measures how much of your bite problem is teeth and how much is jaw, and that measurement drives the honest answer.
Is my teenager responsible enough for aligners?
Only you and your teen can answer that — but here’s the test we’d suggest. Aligners must be worn 20 to 22 hours a day, every day, through school, sports and social life, and kept track of every time they come out for a meal. Some teens handle that routine well and prefer aligners precisely because they’re discreet. Others lose retainers, forget cases and leave appliances in lunch bags — and for them, braces are the safer plan, because braces don’t depend on daily discipline to work. There is no wrong answer about your teen’s habits; there is only an expensive way to learn it. If the honest read is “not yet”, braces now keeps every option open later.
Do I really have to wear them 22 hours a day?
The standard recommendation is 20 to 22 hours a day, and it isn’t padding. Each tray is shaped for a small step toward the final position, and teeth only move while the tray is on them. Wear them less and two things happen: the steps stop tracking (the next tray fits poorly or not at all), and teeth begin drifting back during the hours the trays are out.
The hours out are for eating, drinking anything other than water, and brushing and flossing — which is a workable routine for most people, but it does ask for consistency. If that schedule genuinely doesn’t fit your life right now, say so at the assessment; a plan you can keep beats a plan you can’t.
Does the CDCP cover clear aligners?
No. The Canadian Dental Care Plan (Canada.ca) does not cover orthodontic treatment, and clear aligners are orthodontics — Canada.ca states that orthodontic services are currently not available under the plan. So aligner treatment is a private expense whether or not you are a CDCP patient, and no part of an aligner plan should be budgeted around CDCP coverage, because that coverage isn’t there. The CDCP does cover other care for eligible patients — exams, cleanings, fillings, dentures and more — and our team can explain how your eligibility affects the rest of your dental care. But for straightening teeth, the plan doesn’t pay, and anyone who tells you otherwise is mistaken.
Does it matter which clear aligner system is used?
Less than the marketing suggests. Aligner systems differ in their planning software, materials and details, and your dentist works with the system they judge fits your case — but the label is not what straightens your teeth. The three things that decide your result are the assessment (was candidacy judged honestly?), the plan (are the movements realistic for trays?), and your wear (20 to 22 hours a day, as directed). At Vita Dentistry we provide clear aligner treatment; your assessment confirms which approach suits your teeth and bite. If a search brought you here under a brand name, that’s fine — bring the question, and we’ll talk about the treatment itself.
I had braces as a teenager and my teeth have moved back. Can aligners help?
Often, yes — relapse after earlier orthodontic treatment is one of the most common reasons adults choose aligners. Because the teeth were straight once and the movements needed are usually modest, these cases are frequently well suited to trays, and treatment is often shorter than a from-scratch plan. Two honest notes: the assessment first confirms why the teeth moved (a lost or unworn retainer is the usual story) and checks that the bite is otherwise healthy; and this time, the retainer at the end is not optional — teeth that have drifted once will drift again without one, and ongoing night-time retainer wear is what protects the second result.
What if I’m told I’m not a candidate?
Then you’ve learned something worth knowing before spending anything — and “not a candidate for aligners” is not “nothing can be done”. Depending on the reason, the path might be treating gum disease or cavities and reassessing, choosing braces for movements aligners can’t make, a staged plan that does the hard movements first, or a referral to a specialist orthodontist for a complex bite. The section above — “What happens if you’re not a candidate yet” — walks through the common versions. What we won’t do is reshape the recommendation to fit the appliance we happen to be discussing; the recommendation follows your teeth, not the other way around.
Will I need retainers after clear aligner treatment?
Yes — everyone does, after aligners and after braces alike. Teeth are held in place by fibres and bone that remodel slowly, and for a long time after treatment they tend to drift back toward their old positions. A retainer holds them while everything settles, and ongoing night-time wear is what protects the result long-term. Think of the retainer as part of the treatment, not an optional extra — and factor it into your decision, because straightening without retaining usually means paying to straighten twice.
