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 dentist 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.
Most Common Things That Can Stain Teeth
- Wine and fizzy drinks consumed in excess
- Other foods and oral tobacco products with strong colours
- Chlorhexidine, which is a chemical bactericidal and bacteriostatic, used as antiseptic in mouthwashes and toothpastes for the treatment of gingivitis and halitosis. Chlorhexidine doesn’t stain the teeth but it destroys the bacteria in the plaque which allows other staining agents to discolour the accumulation if the plaque isn’t removed.
