What is Teeth Whitening?

Tooth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surface. It cannot make a complete colour change, but it may lighten the existing shade.

Methods of Teeth Whitening . Professional bleaching is the most usual method of tooth whitening. Your dentist will be able to tell you if you are suitable for the treatment, and will supervise it if you are. First the dentist will put a rubber shield or a gel on your gums to protect them. They will then apply the whitening product to your teeth, using a specially made tray which fits into your mouth like a gum-shield.

Home kits are cheaper. Because tooth whitening is a complicated procedure we advise that you always talk to your dentist before starting the treatment. You could buy a Teeth Whitening Bleaching LED Light Accelerator from a Dental Equipment store and do it yourself at home.

Why choose Teeth Whitening?

Most of us start out with sparkling white teeth, thanks to their porcelain-like enamel surface. Composed of microscopic crystalline rods, tooth enamel is designed to protect the teeth from the effects of chewing, gnashing, trauma and acid attacks caused by sugar. But over the years enamel is worn down, becoming more transparent and permitting the yellow color of dentin - the tooth's core material - to show through.

During routine chewing, dentin remains intact while millions of micro-cracks occur in the enamel. It is these cracks, as well as the spaces between the crystalline enamel rods, that gradually fill up with stains and debris. As a result, the teeth eventually develop a dull, lackluster appearance.

Teeth whitening removes the stains and debris, leaving the enamel cracks open and exposed. Some of the cracks are quickly re-mineralized by saliva, while others are filled up again with organic debris.

Actually teeth whitening has side effects. Some people may find that their teeth become sensitive to cold during or after the treatment. Others may have discomfort in the gums, a sore throat or white patches on the gum line. These symptoms are usually temporary and should disappear within a few days of the treatment finishing.
