Tooth Whitening

According to the ADA (American Dental Association)there are some basic questions most people ask:

What should you ask your dentist?

You may want to start by speaking with your dentist. He or she can tell you whether whitening procedures would be effective for you. Tooth whiteners may not correct all types of discoloration. For example, yellow hued teeth will probably bleach well, brownish-colored teeth may bleach less well, and grayish-hued teeth may not bleach well at all. Likewise, bleaching may not enhance your smile if you have had bonding or tooth-colored fillings placed in your front teeth. The whitener will not affect the color of these materials, and they will stand out in your newly whitened smile. In these cases, you may want to investigate other options, like porcelain veneers or dental bonding.

What is in-office bleaching?

If you are a candidate for bleaching, your dentist may suggest a procedure that can be done in his or her office. This procedure is called chair side bleaching and may require more than one office visit. Each visit may take from 30 minutes to one hour.

During bleaching, the dentist will apply either a protective gel to your gums or a rubber shield to protect the oral soft tissues. A bleaching agent is then applied to the teeth, and a special light may be used to enhance the action of the agent. Lasers have been used during tooth whitening procedures to enhance the action of the whitening agent.

What are at-home tooth whitening procedures and products?

There are several types of products available for use at home, which can either be dispensed by your dentist or purchased over-the-counter.

Bleaching solutions. These products contain peroxide(s), which actually bleach the tooth enamel.

Peroxide-containing whiteners typically come in a gel and are placed in a mouth guard. Usage regimens vary. Some products are used for about twice a day for 2 weeks, and others are intended for overnight use for 1-2 weeks. If you obtain the bleaching solution from your dentist, he or she can make a custom-fitted mouth guard for you that will fit your teeth precisely.
