I understand that the teeth whitening gel that dentists use are made of peroxide. I was thinking about saving some time going back and forth to the dentist by just whitening with the peroxide I have at home. How long would I have to keep it on? Do you have any recommendations for how to go about it?

Dear Laurie,

Teeth Bleaching trays in their case
Teeth Whitening Trays

 

While it is true that dentists use a peroxide to whiten teeth, it is not the peroxide you are purchasing over the counter. Using over-the-counter peroxide That is a liquid 3% solution, which is very weak. What your dentist uses is a gel that is at least 33% peroxide. It’s significantly stronger.

If you were to  try to do this yourself, you would need to keep the peroxide on your teeth for a minimum of fifteen minutes at a time for it to penetrate the teeth. Because it would be liquid that would mean that you would have to keep swishing it around in your mouth for that length of time. Not only would that be uncomfortable for you and impractical, but there is a negative medical side effect, too.

This is because peroxide is great at killing bacteria. The only problem with that is it does not distinguish between good an bad bacteria. As a result, you will end up with an oral yeast infection on the soft tissue in your mouth.

The safest thing for you to do is to have professional teeth whitening done. Not only is the whitening more effective because it is stronger and in gel form, but your dentist will provide you with a custom fitted tray that you will wear over your teeth. This will keep the gel on your teeth while protecting your mouth and gums. You won’t have to go back and forth, You can wear the trays at home and your dentist will provide you with the gel to take with you.
