The teeth that lose their natural and aesthetic color by various reasons can be whitened with various methods. This is done with a variety of chemicals that do not damage the teeth. These applications, also known as bleaching, are applied to one or several times.
Teeth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the teeth surface. It cannot make a complete colour change, but it may lighten the existing shade.
What does tooth whitening involve?
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.
The ‘active ingredient' in the product is usually hydrogen peroxide or carbamide peroxide. As the active ingredient is broken down, oxygen gets into the enamel on the teeth and the tooth colour is made lighter.
