Read the answers to our FAQs below.

What are Invisalign clear aligners?

Invisalign is a series of clear orthodontic aligners that straighten your teeth without traditional metal braces.

Based on a customized treatment plan, a series of custom aligners will be created to fit your teeth during each stage of your treatment.

How does Invisalign work?

Invisalign clear aligners are designed to move your teeth by small increments during your treatment. Each aligner is worn for about two weeks and then replaced with the next one in the series.

This process will continue until your teeth are in their new positions. The length of your treatment will be determined by your dentist based on your unique needs.

How long does Invisalign take?

Only your dentist can determine the duration of your individual Invisalign treatment.

That's because factors like the misalignment of your teeth and jaw, the shape of your bite, and the amount of movement required to correct the issues will all affect the process.

What are Invisalign aligners made of?

Invisalign clear aligners are made with USP Class VI medical-grade, high molecular weight, polyurethane resins, and are BPA free.

How often do I have to visit the dentist?

Invisalign clear aligners do not require adjustments or tightening like traditional braces do, so you will only need to visit the dentist for brief appointments every four to six weeks during your treatment. 

At these appointments, your dentist will review your progress and general oral health and answer any questions you may have.

What are the primary features of Invisalign?

Invisalign aligners are:

  • Discreet and barely noticeable
  • Smooth and comfortable
  • Removable for eating, drinking, brushing and flossing

How much does Invisalign cost?

The cost of  Invisalign treatment depends on your individual case.

For example, the more severe your misalignment issues, the more aligners you will need and the more treatment will cost.

Generally, the cost of Invisalign treatment is comparable to that of traditional metal braces.

How will Invisalign fit my lifestyle?

Most patients find that Invisalign fits very comfortably into their day-to-day lives.

You can remove the aligners for eating, drinking, brush and flossing, so there are no dietary or lifestyle restrictions.

And because of the low profile appearance, many people won't even notice you're wearing them, making the impacts on your social life minor. 

Are there any food or drink restrictions?

No, because you can remove Invisalign clear aligners to eat and drink, you can continue to enjoy all the things you love.

How many sets of aligners will I need?

Your dentist can give you an accurate estimate of how many aligners you need and how long your treatment will take based on your specific case. 

Can adults use Invisalign?

Yes, any adult who has healthy teeth and gums is a potential candidate for Invisalign.

Can teenagers use Invisalign?

Yes, teens can certainly be candidates for Invisalign. In fact, Invisalign has a line of aligners tailored to the needs of teenagers that offer a number of features including compliance indicators, stageable eruption tabs and six sets of replacement aligners.

How often do I have to change my aligners?

Generally, patients switch to the next set of aligners about every two weeks. Your dentist can tell you exactly how often you should switch out your aligners based on your individual treatment plan.

How do I clean my aligners?

  • Rinse your aligners each time you remove them.
  • Soak your aligners using denture cleaner, Retainer Brite, and/or the official Invisalign cleaning crystals.
  • Brush and floss your teeth before you put your aligners back in. 
  • Gently brush your aligners with a clear, anti-bacterial soft soap, and then rinse them off.

Can I play sports with Invisalign?

You can remove your clear aligners while you play sports so you don't have to worry about them getting damaged.  

You'll also want to invest in a sports mouth guard to protect your teeth during sports.

Can I play my musical instrument with Invisalign?

Yes, you can remove your aligners to play your instrument, and put them back in when you're done.

How do I store my aligners?

Invisalign aligners will come with a storage case, and this is where you should keep them whenever you remove them to keep them safe.
