Teeth whitening is a harmless procedure and causes no permanent damage to the enamel.

Typically, you can expect whitening to last up to two years, however, it will depend on the individual. For the best results, it is advised to avoid coffee, red wine and smoking as these all cause staining of the teeth.

Teeth whitening has been researched for over 20 years and there are no adverse reactions to it.

Most people can have teeth whitening, provided they are not pregnant or allergic to the whitening gel. If you have all dental crowns, bridges or veneers, then unfortunately teeth whitening will not be suitable for you as porcelain cannot be whitened.

If sensitivity from tooth whitening is to occur, it will only be during the early stages of treatment. Sensitivity will disappear within 1-3 days of stopping treatment. Tissue irritation most commonly results from an ill-fitting mouthpiece tray rather than the tooth bleaching agent. There will be no long-lasting effects on tooth sensitivity post whitening treatment.
