Is professional teeth whitening safe? What to expect
How in-studio and take-home whitening work, how white you can go and how to avoid sensitivity.
Professional whitening is one of the safest cosmetic treatments in dentistry when it is planned and supervised by a dentist. Here is what happens and how to get the best result.
In-studio or take-home?
In-studio whitening brightens your teeth several shades in about an hour. Custom take-home trays work more gradually over two weeks and are great for topping up later. Many patients combine the two.
Avoiding sensitivity
- Have a check-up and clean first.
- Use a sensitivity toothpaste for two weeks before.
- Skip coffee, tea and red wine for 48 hours after.
- Never use whitening gel stronger than your dentist recommends.
