Teeth Whitening


Tooth whitening lightens teeth and helps to remove stains and discoloration. Whitening is among the most popular cosmetic dental procedures because it can significantly improve how your teeth look. Most dentists perform tooth whitening.

Whitening is not a one-time procedure. It will need to be repeated from time to time if you want to maintain the brighter colour.

Professional bleaching is the most usual method of tooth whitening.  First, the dental team will put a rubber shield or 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 mouth guard.

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.

The whole treatment can usually be done within three to four weeks. First, you will need two or three visits to the dentist. Your dental team will need to make a mouthguard and will take impressions for this at the first appointment. Once your dental team has started the treatment, you will need to continue the treatment at home. That means regularly applying the whitening product over two to four weeks, for 30 minutes to one hour at a time.

There is now laser whitening or ‘power whitening.’ During this procedure, a rubber dam is put over your teeth to protect the gums, and a bleaching product is painted onto your teeth. Then a light or laser is shone on the teeth to activate the chemical. The light speeds up the reaction of the whitening product, and the colour change can be achieved more quickly. Laser whitening is said to make teeth up to five or six shades lighter.
