The Basics of Tooth Whitening
Tooth whitening is also popularly known as tooth bleaching. The process helps to whiten your teeth by eliminating discolouration and stains. Teeth stains can be due to long-term ingestion of drinks such as coffee, tea and red wine. Tobacco also contributes to teeth discolouration. Many people prefer this method of cosmetic dental treatment because of how quickly it improves their smile. Most dentists offer this treatment. According to extensive studies, most of the teeth whitening procedures that take place under the direct supervision of a dentist are usually safe.
