Can i whiten my teeth

Many adults can whiten natural teeth after an examination, but fillings, crowns, decay, gum disease, and some stains need separate planning.

Whitening gels use peroxide to oxidise some tooth pigments; they do not lighten fillings, crowns, veneers, or the exposed root surface. Eligibility depends on healthy gums, intact teeth, the cause of discolouration, and the treatment goal.

A dentist may clean the teeth, treat decay or gum inflammation, record the starting shade, and prescribe custom trays or provide an in-office protocol. Follow the gel concentration, contact time, and wear schedule exactly.

Seek an examination before whitening if you have pain, cavities, cracked teeth, gum recession, or strong sensitivity. Stop and contact the provider if burning or severe sensitivity develops.

Ask what will and will not change colour, whether existing restorations will need replacement for shade matching, and which supervised method suits you.
