The short answer
Invisalign uses removable clear aligners and suits most mild to moderate crowding, spacing and relapse cases, typically taking 6 to 18 months with 20 to 22 hours of daily wear. Traditional braces remain more predictable for severe rotations, significant bite corrections and large tooth movements.
Most adults who ask us about straightening their teeth are not looking for a teenage orthodontic experience. They want the result without the metal, and in the majority of cases clear aligners deliver exactly that. But it is worth understanding where each approach is genuinely stronger.
What Invisalign does well
- Nearly invisible in conversation and in photographs.
- Removable for eating, so there are no food restrictions.
- Brushing and flossing stay completely normal, which protects gum health during treatment.
- Fewer emergency visits — no brackets to pop off and no wires to poke.
- Digital planning lets you preview the projected result before you commit.
- Often fewer chair visits, with progress checks roughly every six to ten weeks.
Where traditional braces still win
- Severely rotated teeth, particularly premolars and canines.
- Large vertical movements — intruding or extruding a tooth substantially.
- Complex bite corrections and cases involving extractions.
- Patients who know they will not wear a removable appliance consistently.
The discipline factor
This is the single biggest predictor of success with aligners. They only move teeth while they are in your mouth, and the plan assumes 20 to 22 hours per day. Patients who take them out for long lunches, meetings and evenings out fall behind schedule and end up needing refinement trays. Braces work whether or not you feel like cooperating that week — for some people that is a genuine advantage.
Cost and timing
For comparable cases, Invisalign and braces land in a similar range, and most dental plans that include orthodontic benefits treat them the same way. Simple cases — minor crowding, closing a small space, correcting relapse after childhood braces — can finish in six to nine months. Comprehensive cases usually run twelve to eighteen. We give you a case-specific estimate after imaging rather than a headline number that turns out not to apply to you.
Retainers are not optional
Teeth remember where they used to be. Whichever method you choose, nightly retainer wear is what keeps the result. The most common reason adults come to us for a second round of alignment is a retainer that was abandoned years ago.
Straightening is also a health treatment
Crowded and overlapped teeth trap plaque in places floss cannot reach well, which raises the risk of decay and gum disease. An uneven bite concentrates force on a few teeth and shows up years later as worn edges, cracks and sensitivity. Alignment is often framed as cosmetic, and it does transform a smile — but the functional payoff is real.

Frequently asked questions
- Does Invisalign work as well as braces?
- For mild to moderate crowding, spacing and relapse cases, aligners produce results comparable to braces. For severe rotations, large vertical movements and complex bite corrections, fixed braces remain more predictable.
- How many hours a day do I need to wear my aligners?
- 20 to 22 hours per day. Aligners should be out only for eating, drinking anything other than water, and brushing.
- Am I too old for Invisalign?
- No. Teeth can be moved at any age as long as the gums and supporting bone are healthy. A meaningful share of aligner patients are in their forties, fifties and beyond.
