How Does Teeth Whitening Work?
Most professional teeth whitening is performed in the dentist’s office. The process begins when your dentist applies a whitening agent on your teeth, which is left in place for about twenty minutes. Then this whitening agent is removed and re-applied. A tooth whitening session usually lasts about an hour, producing dramatic results and lightening your teeth from five to ten shades.
Your dentist may recommend a take-home kit for at-home tooth whitening if more in-depth whitening is needed for resistant staining. If this is the case you will be supplied with special, custom-made trays to wear. The trays are usually worn for 15 minutes at a time twice a day. This process provides a more prolonged exposure to the whitening agent, increasing the odds of removing stubborn or severe staining.
Is Tooth Whitening Safe?
A tooth whitening that is performed by your Manhattan Beach Cosmetic Dentist is very safe. Prior to in-office whitening, your dentist will place a protective gel on your gums and lips. This gel protects sensitive tissues from direct contact with the whitener. In the unlikely event that the whitening product does make some contact with your lips or gums, you may experience some irritation, but it is not severe and will wear off quickly.
