It’s a protocol that is done by trained and experienced dentist or technician. A reasonably high concentration peroxide gel is used in this process. The process is done carefully and in a controlled environment. First, gums are protected with a paint on rubber dam and then the high concentration peroxide is used on the teeth. The peroxide is kept on the teeth for 15 to 20 minutes to one hour at most. If the patient has stubborn staining problem, in that case, repeat use of the process may be necessary.

Hydrogen peroxide and carbamide peroxide
Hydrogen peroxide is used in teeth whitening mostly in in-office whitening. It is very powerful and fast acting and so it is used when the duration is very short. The concentration may vary from 9% to 40% depending on the use.
On the other hand, carbamide peroxide is used in at home teeth whitening kits. It is slow acting. Carbamide peroxide breaks down to hydrogen peroxide and it has about one third of the strength of hydrogen dioxide. These are generally used in kits which are used at home so that you do not need special training to use them and they are also safe for use by anyone.

Once you get your teeth whitened, it is very important to maintain the results. If you want to extend the longevity, there are a few things that you need to do. At home follow up or maintenance of the whitening may be necessary at a short interval. In some cases, the maintenance may be necessary only once a year.
