FAQs
What is teeth whitening?
Teeth whitening is a cosmetic dental procedure that aims to lighten the colour of the teeth and remove stains and discolouration. It can be performed in-office by a dentist or at home using over-the-counter or dentist-prescribed whitening products.
How does teeth whitening work?
Teeth whitening works by using bleaching agents such as hydrogen peroxide or carbamide peroxide to break down stains and discolouration molecules on the surface and within the tooth enamel, resulting in a brighter, whiter smile.
What types of teeth whitening are available?
There are two main types of teeth whitening: in-office whitening, which is performed by a dentist using professional-grade bleaching agents and specialised equipment, and at-home whitening, which involves using whitening kits, strips, or trays provided by a dentist or purchased over-the-counter.
Is teeth whitening safe?
When performed under the supervision of a dentist and according to manufacturer instructions, teeth whitening is generally considered safe and effective. However, some individuals may experience temporary tooth sensitivity or gum irritation during or after treatment.
How long does teeth whitening last?
The longevity of teeth whitening results varies depending on factors such as oral hygiene habits, dietary habits, and lifestyle factors such as smoking or consuming staining substances. On average, teeth whitening results can last from several months to up to three years.
Can teeth whitening damage my teeth?
When performed correctly, teeth whitening should not damage the teeth or enamel. However, overuse of whitening products or misuse of whitening treatments can lead to tooth sensitivity, gum irritation, or enamel erosion. It’s essential to follow recommended guidelines and consult with a dentist before whitening your teeth.
Who is a good candidate for teeth whitening?
Good candidates for teeth whitening are individuals with healthy teeth and gums, minimal dental restorations (such as fillings or crowns) on visible teeth, and stains or discoloration that are primarily extrinsic (on the surface of the teeth).
Can teeth whitening remove all types of stains?
Teeth whitening is most effective at removing surface stains caused by food, beverages, tobacco, and aging. However, certain types of intrinsic stains (within the tooth) may not respond well to whitening treatment and may require alternative cosmetic dental procedures such as veneers or bonding.
