What professional cleaning does
Cleaning removes deposits that home brushing cannot always remove and supports the assessment and management of gum health. It may improve the appearance of surface staining, but it does not chemically lighten the natural tooth colour.
What whitening does
Whitening uses a bleaching process to lighten suitable natural teeth. It does not lighten crowns, veneers or tooth-coloured fillings in the same way, so existing restorations and the desired shade need to be considered.
Why a dental check comes first
Sensitivity, decay, cracks, gum inflammation, exposed roots and some kinds of discolouration may require attention before whitening. A dentist can help determine whether whitening is appropriate and explain possible temporary sensitivity or gum irritation.
- Discuss existing sensitivity.
- Identify crowns, veneers and visible fillings.
- Check teeth and gums before whitening.
- Ask what degree of change is realistic.
Avoid one-size-fits-all shade promises
Natural tooth colours and types of staining differ. A responsible discussion focuses on a healthy, realistic improvement rather than guaranteeing a particular shade or a permanent result.
