We’ll answer the most frequently asked questions about tooth whitening below!

Is teeth whitening permanent?

Teeth whitening isn’t permanent. The whitening effect can last anywhere from 6 months to 3 years, varying significantly from person to person.

To make your teeth stay whiter longer, note these tips:

  • Avoid foods and drinks that easily stain your teeth, such as coffee, red wine, and tea
  • Don’t smoke
  • Brush your teeth twice a day
  • Floss daily
  • Visit your dentist for routine checkups and cleanings

How long does teeth whitening take?

This varies depending on the type of tooth whitening treatment.

If you’re using whitening strips, you may need to attach the strips to your teeth for 1 to 2 hours per day for up to two weeks.

With trays and gels, it’ll depend on the strength of the product. You may need to treat your teeth once a day for anywhere from 1 to 4 hours.

While the at-home methods may seem convenient, they require more time and energy.

A professional in-office teeth whitening session ranges from 30 to 90 minutes, depending on the severity of the stains.
