Important Facts About Teeth Bleaching

By Marla Mills


There are a number of reasons that contribute to tooth discoloration or staining over the years. Examples include levels of oral hygiene, the intake of certain medications and eating habits. Stained teeth can be bleached to improve their appearance. The teeth bleaching procedure involves the utilization of oxidizing agents like carbamide peroxide to bleach them.

Whitening can also be done by using a special gel that is placed in a flexible custom tray worn around the teeth for a particular period of time. After this tray is removed, you should use a second whitening agent and a special light which activates the chemical reaction. Whitening agents react with tooth enamel and this reaction oxidizes the stain deposits.

When the tooth whitening procedure is performed repeatedly, the bleach gets into the dentine layer. When complete, this process removes all the signs of discoloration and the outcome is a dazzling white smile. Dentists perform this procedure in two ways. One of them involves applying a layer of oxidizing agents to the teeth and flushing this layer away after a short period.

Dentists usually use a thirty five percent hydrogen peroxide equivalent to perform whitening procedures. This tooth whitening method is fast and effective even though there are some risks involved. The whitening agent can cause damage to the soft tissues of the mouth. However, this risk is minimal because the dentist supervises the process.

The other bleaching method that a dentist can use involves placing the whitening agent in a strip that is then attached to the teeth. This strip is not removed right away. It has to stay in place for some hours or days depending on what a dentist recommends. Even if it takes a while to work, it is safe because the risk of soft tissue damage is significantly reduced.

Some stains such as those caused by prolonged use of antibiotics like tetracycline do not respond to whitening quickly. In this case, a person is required to undergo repeated tooth bleaching procedures so that the bleach can penetrate the dentine layer to bring out the desired effects. Newer tooth whitening procedures now involve using light to speed up the whitening effect of bleach.

The results of bleaching procedures vary from one person to another even though they are effective in getting rid of discoloration and stains. After undergoing the procedure, most people find that their teeth have become fairly sensitive. Dentists advise their patients to refrain from drinking hot or cold beverages for a certain period of time. At times, dentists provide their patients with fluoride treatment after the procedure to lessen sensitivity.

Your dental insurance policy may not cover for expenses associated with teeth bleaching. If you feel that it is too costly to use the services of a dentist for this procedure, you can purchase a tooth whitening kit from your local drug store. Tooth whitening kits are effective but you may not see the results immediately. You should therefore be patient as you use them.
