Teeth whitening is one of the most popular cosmetic dental treatments. It is suitable for people who have had their teeth thoroughly checked by a dentists first.
The different methods include in-practice bleaching, which is applied by a professional dentist; at-home bleaching, which is used at home by the patient; whitening strips, which are used by the patient and whitening toothpaste.
Bleaching is not recommended if there is tooth decay or infected gums, it is most effective on yellow discoloured teeth and least effective when the original tooth colour is greyish. It doesn’t work where teeth have been filled or bonded.
