Why so many patients choose clear aligners
Clear aligners are now one of the most popular ways adults choose to straighten their teeth, and for good reason. They're quietly worn during the day, easy to remove for meals, and they keep brushing and flossing simple, no brackets or wires to navigate.
For the right patient, Invisalign can:
- Improve a smile that's always felt crowded or crooked
- Close small gaps between teeth
- Address mild to moderate bite issues
- Refine teeth that have shifted slightly years after braces
We're careful, though, to keep expectations realistic. Invisalign is for selected patients: the cases where it's truly the best fit. If we don't think aligners will give you a great result, we'll tell you, and we'll talk through what would.
What treatment looks like with us
We approach Invisalign the same way we approach every long-term treatment: carefully, conservatively, and at a comfortable pace. Here's how it typically unfolds:
Consultation & assessment
We listen first. What's bothering you? What would feel like a win? Then we do a focused exam and let you know whether Invisalign is a good fit for your case, or whether a different approach might serve you better.
Digital scanning & treatment plan
If we move forward together, we take a quick digital scan of your teeth (no goopy impression material) and use it to design a step-by-step movement plan. We'll show you a preview of how your smile is expected to change.
Aligners & easy check-ups
Your custom aligners are made and you start wearing them, switching to a new set every one to two weeks as prescribed. Check-ups are short and relaxed (usually every six to ten weeks) to make sure everything is tracking as planned.
Finishing touches & retainers
Once you've reached your final aligner, we may suggest small refinements or simple polishing to get the final result just right. Then we fit you with custom retainers and set you up with a long-term wear plan to protect the result.
Aligners vs. braces, compared
Aligners aren't always the right tool. Here's how we usually frame the choice:
- Aligners shine when the movements needed are mild to moderate, when discretion matters, and when the patient is reliable about wearing them.
- Braces still win for some more complex bite corrections, growth-related cases, and certain rotations or extractions.
If you want a fuller comparison, our page on orthodontics and braces is a good companion read.
What good Invisalign care really requires
Aligners only work when you wear them. The most successful patients we treat tend to share a few simple habits:
- Wear the aligners 20–22 hours a day
- Remove them for meals and anything other than water
- Clean teeth (and the aligners) before putting them back in
- Keep the next set with you in case you need to switch on schedule
It sounds simple, and it really is, but consistency is the whole game.
How long does Invisalign take?
Most cases run 12 to 18 months, though the honest range is wider than that. Minor crowding or a single rotated tooth can be finished in as little as six months. Complex bite correction can run past two years, and some cases are better served by braces entirely.
Three things drive the timeline more than anything else:
- How far the teeth need to move. Tipping a tooth is quick; bodily movement or rotating a round tooth like a premolar takes considerably longer.
- How consistently you wear the aligners. This is the big one. Aligners work about 20 to 22 hours a day. Wearing them 14 hours a day does not slow treatment proportionally — it stalls it, because teeth drift back between wears.
- Whether refinements are needed. It is common and not a failure: near the end, a second short series of aligners fine-tunes the result. Budget for the possibility.
You will usually start seeing visible change within the first two to three months, well before the case is finished. For how this compares with fixed appliances, see Invisalign vs braces.
Can Invisalign be covered by OHIP?
No. OHIP does not cover Invisalign, and it does not cover orthodontic treatment of any kind — clear aligners, fixed braces, or retainers. It does not cover routine dentistry in Ontario at all. Dentistry sits outside the provincial health plan, and orthodontics sits outside it twice over.
The narrow OHIP exceptions concern hospital-based oral and maxillofacial surgery for medical reasons: reconstruction after facial trauma, treatment connected to oral cancer, or correction of some severe congenital jaw conditions. Even in those cases, the hospital and surgical components may be covered while the orthodontic work is not.
The Canadian Dental Care Plan does not cover it either. Orthodontics — including Invisalign and braces — is excluded from the CDCP at every income level, alongside implants and cosmetic treatment. This is worth stating plainly because it is a common and expensive assumption.
That leaves three realistic routes:
- Extended dental insurance. Many employer plans carry a separate lifetime orthodontic maximum, distinct from your annual dental maximum. It is frequently restricted to dependants under a certain age, so check whether adult orthodontics is included before assuming coverage.
- Payment plans. Aligner treatment runs over many months, and staged payment across that period is standard rather than exceptional.
- The Medical Expense Tax Credit. Orthodontic treatment recommended for function rather than appearance alone can be an eligible medical expense. See our note on how the credit works — the mechanism is identical for orthodontics.
Ask your insurer for a pre-determination before treatment starts. We will submit the proposed plan and you get the coverage answer in writing rather than discovering it afterwards.
What actually changes the cost of Invisalign
We do not publish prices, because a number without a case attached to it is misleading — the same headline figure can cover wildly different amounts of treatment. What we can do is tell you exactly which levers move it, so you can read any quote, from us or anyone else, and understand what you are comparing.
Case complexity. This is the largest factor by a distance. Minor crowding on the front teeth is a fundamentally different undertaking from correcting a bite discrepancy. More movement means more aligners, more chair time, and more planning.
Treatment length and aligner count. Aligner treatment is priced substantially on the number of trays in the series, and that number follows directly from how far the teeth need to travel. This is why a six-month case and a two-year case are not variations on one price.
One arch or both. Treating the upper arch alone costs meaningfully less than treating both. Whether that is clinically appropriate depends on your bite, not your budget — but it is a real question worth asking.
Refinements. A short second series to fine-tune the result near the end is common and not a failure. Ask whether refinements are included in the quoted plan or billed separately; practices differ, and this is the single most common source of surprise.
Attachments and interproximal reduction. Small tooth-coloured attachments give the aligners something to grip, and creating slight space between crowded teeth is sometimes necessary. Both add appointment time.
Retainers afterwards. Retention is not optional — teeth drift back without it. Check whether the first set of retainers is included in the treatment fee or quoted separately, and what replacements involve.
Preparatory treatment. Aligners move teeth through bone, so active decay or untreated gum disease has to be resolved first. That work is separate from the orthodontic plan and comes before it.
When you compare quotes, compare what is included rather than the headline figure: number of aligners, refinements, retainers, and follow-up visits. Two plans with the same total can contain very different amounts of care. We provide a written, itemized treatment plan before anything begins.
After your treatment: the part most people forget about
Teeth try to drift back to where they used to be. That's why retention is just as important as the treatment itself. At the end of your case, we'll provide custom retainers and a long-term wear schedule that fits into your life. With a few simple habits, your new smile can stay where it is for decades.
Curious whether Invisalign is right for you?
Book a consultation and we'll take a look, talk through the trade-offs, and give you our honest opinion. If we don't think Invisalign is the best fit, we'll say so and recommend what would be. You can also see how this fits alongside our general dentistry and new patient experience.
