Does getting your teeth whitened damage them

Teeth whitening usually affects stain molecules rather than removing tooth structure, but peroxide can cause temporary sensitivity or gum irritation.

Teeth whitening is a chemical treatment for discolouration, not a polish that makes every dental material lighter.

Have a dental examination first, then follow the prescribed gel concentration, tray fit, and wear time.

Arrange an examination if pain persists, a tooth becomes painful to bite, or a gum patch develops.

Ask whether your enamel, dentin, fillings, and gum margins are suitable for whitening.
