Professionally whitened teeth

Professional tooth whitening is performed after an examination using a peroxide gel and controlled exposure, with the gums protected from direct contact.

The appointment may include cleaning, recording the starting shade, isolating the gums, applying peroxide gel for a timed interval, and discussing sensitivity. Existing restorations may need a separate colour-matching plan because whitening does not recolour them.

A dentist first distinguishes surface stain from internal discoloration and checks enamel, dentine, decay, cracks and restorations. The whitening agent changes natural tooth colour, but not the shade of crowns, fillings or veneers.

The clinical process may include cleaning, shade recording, gum isolation, gel application and timed activation or a custom tray. The dentist then explains sensitivity care and whether existing restorations could look mismatched. Arrange a consultation before treatment if you have cavities, gum recession, cracked teeth, pulp symptoms or marked sensitivity. Contact the practice if pain, gum irritation or an uneven result persists.

Ask which discoloration is being treated, what material will be used, how the gums will be protected, whether restorations need replacement for colour matching, and what aftercare is required.
