Teeth tend to change colour over time and they usually yellow with age. These changes can be reversed with a tooth whitening or bleaching procedure.
The chemical which is applied to the teeth is carbamide peroxide. This reacts with the acid on the teeth to change and become hydrogen peroxide, a powerful bleaching agent.
The procedure itself is painless,This is a quicker way of achieving tooth whitening, Depending on the technique chosen, your dentist may use a special shield to protect your gums., and this works after it is exposed to a special light source which helps to speed up the bleaching process. Individual teeth can be targeted using this method, or the whole mouth can be treated. This procedure can take from 30to 45 minutes . depending on the number of teeth requiring treatment.
