In-clinic or take-home whitening, where the enamel and existing restorations allow it.
Teeth whitening uses a peroxide-based gel to lighten the natural colour of tooth enamel. It can be done in the clinic in a single session, at home with custom trays over a couple of weeks, or with a combination of both.
Whitening only works on natural teeth. Crowns, veneers and fillings keep their colour, so they may need replacing if you want them to match newly whitened teeth.
These are general points only. Your dentist confirms what is suitable after an examination, which usually includes X-rays or a 3D scan, and may recommend a different or more conservative option.
The dentist checks for decay, gum problems and existing restorations, and records your starting shade.
Your gums and lips are protected so the gel only touches the teeth.
The gel is applied in timed cycles in clinic, or you are given custom trays and gel for home use.
The new shade is checked and you receive advice on keeping the result.
Teeth can be more sensitive and more prone to staining. Avoid very hot or cold food and strongly coloured food and drinks.
Any sensitivity usually settles. A sensitivity toothpaste can help.
The colour gradually fades, especially with coffee, tea, red wine or smoking. Occasional top-ups can maintain it.
Timelines vary between people. Always follow the aftercare instructions from your treating clinic.
Professional whitening used as directed is generally considered safe for enamel. Overuse or unregulated products can cause problems.
Results commonly last from several months to a few years, depending on diet, smoking and oral hygiene.
Often yes, if you plan to keep some natural teeth visible. New restorations are then matched to your whitened shade.
