Teeth vary in colour just like hair and skin do. Even if they are healthy, they may be yellow or darker in colour than white teeth. Older people also tend to have yellowish or darker teeth. Teeth might also become darker if their roots have been damaged or the nerve has died.

The colour of the teeth can be lightened with Hydrogen Peroxide which can be used on either the outside or the inside of the teeth. This process is called bleaching. Tooth bleaching is completely safe as the dentists take special care to see that the bleach does not touch the gums and burn them.

Zoom! Bleaching:

Dentavista clinics use the Zoom! Bleaching method. The Zoom! chairside whitening system is a scientifically advanced, tooth whitening procedure. It is safe, effective and very fast. In just 45 minutes, your teeth will become dramatically whiter. The procedure begins with a short preparation to cover your lips and gums, leaving only your teeth exposed. The Zoom! whitening Gel is then applied with a specially designed light. The Zoom! light and gel work together to gently penetrate your teeth, breaking up stains and discoloration. With proper care, your smile will sparkle for years.

The Zoom! light activated whitening gelís active ingredient is Hydrogen Peroxide. As the Hydrogen Peroxide is broken down, oxygen enters the enamel and dentin, bleaching coloured substances, while the structure of the tooth is unchanged. The Zoom! light aids in activating the hydrogen peroxide and helps it penetrate the surface of the tooth. A study has shown that use of the Zoom! lamp increases the effectiveness of the Zoom! gel by 26% or more, giving an average improvement of eight shades.

During the procedure, patients may comfortably watch television or listen to music. Certain individuals with anxiety may have difficulty undergoing the entire procedure.

The composite procedure takes less than an hour!! The procedure begins with a preparation period followed by 45 minutes of bleaching. In most cases, a cleaning would be done prior to the actual Zoom! whitening session. Generally, there are no side effects of this procedure.

Zoom! bleaching improves the appearance of your teeth without removing any of the natural tooth surface. Zoom! Bleaching is a better option than a crown or veneer if you want to lighten the colour of healthy teeth.
