One of the questions patients ask most often is whether whitening will damage their teeth, and whether the colour will actually stay. Both are fair worries, so here is a plain answer.
The safety question
Professional whitening carried out or supervised by a dentist is considered safe for suitable patients. The important word is suitable: we check first that the staining will respond and that your teeth and gums are healthy enough. Some short-term sensitivity is common and settles on its own.
Will the colour change back?
Whitening lifts staining and lightens the natural shade. It is not permanent, and habits like coffee, tea and tobacco bring staining back over time. We check the shade with you before and after so your expectations are realistic, and we give advice to hold the result longer.
Why a dentist should check first
Over-the-counter kits vary a lot in strength and fit. A dentist checks that whitening is right for you first, which is the part a shelf cannot do. Book a check if you are considering it.
