Whitening uses a dental bleaching product. It does not change the colour of existing crowns, veneers or fillings, which can affect the appearance of the final result.
Start with healthy teeth and gums
Decay, gum problems and existing sensitivity should be assessed first. Tell your dentist about medicines, previous reactions and any current health considerations before discussing whitening.
What are the options?
A dentist may discuss a supervised home system or treatment at the dental practice. The method, instructions and review arrangements should fit your oral condition. This page does not prescribe a particular product or protocol.
Risks and limitations
Tooth sensitivity and irritation of the gums can occur. The amount of colour change varies, is not permanent and cannot be promised in advance. Existing restorations may no longer match the surrounding natural teeth.
Alternatives and aftercare
Professional cleaning may address some surface staining. Sometimes accepting the existing shade is the appropriate choice. Ask about avoiding irritation, caring for your teeth and when to contact the practice if symptoms persist.
