Tooth whitening is one of the easiest ways to give you a whiter and brighter smile. The whitening process can be carried out using a special bleaching gel or by using a special halogen lamp.
Tooth whitening can be a highly effective way of lightening the natural color of your teeth without removing any of the tooth surfaces. It cannot make a complete color change, but it will lighten the existing darkness.
Tooth whitening only works on natural teeth. It will not work on any types of "false" teeth such as dentures, crowns or veneers.
What do Teeth Whitening Involve?
Professional bleaching is one of the most common forms of tooth whitening. Your dentist will apply the whitening product to your teeth, using specifically made tray which fits into your mouth like a gum-shield.
The active component in the tooth whitening product is usually carbamide peroxide or hydrogen peroxide. As the active ingredient is split asunder, oxygen comes into the enamel on the teeth and the color of the tooth is made lighter.
The moment your dentist has started this treatment you will need to continue it at home.
How Long Does Teeth Whitening Take?
The whole treatment can generally be done in term of three to four weeks. This means frequently applying the whitening product at home over two to four weeks, for 30 minutes to one hour at a time.
Though, there are some new products which can be applied for up to eight hours at a time. This means a acceptable result can be achieved in as little as one week.
What are the Side Effects?
Some people may discover that their teeth become sensitive to cold during or after the treatment. Others inform discomfort in the gums, a sore throat or white patches on the gum line. These symptoms are usually provisional and should withdraw within a few days of the treatment finishing.
