How many hours a day do I need to wear clear aligners?

Most treatment plans call for 20 to 22 hours a day — essentially all the time except when you're eating, drinking anything other than water, or cleaning your teeth. Falling short of that slows your progress and can throw the whole sequence of trays off track.

Do clear aligners hurt?

You'll usually feel mild pressure or tightness for a day or two each time you move to a new tray. That sensation is the aligner doing its job. It's generally milder than the soreness that comes with tightening traditional braces and settles quickly.

How long does clear aligner treatment take?

It depends on how much your teeth need to move. Minor crowding or spacing may resolve in a few months, while more involved cases can run to around a year and a half. Your dentist can give you a realistic estimate after assessing your teeth.

Will I need a retainer after clear aligners?

Yes. Teeth have a natural tendency to drift back toward their old positions, so a retainer — usually worn at night — is essential to hold your result. Skipping it is the most common reason people see their straightened teeth relapse.
