Is tooth whitening safe?

Most studies confirm that tooth whitening is safe and effective. Whitening gels that contain carbamide peroxide and hydrogen peroxide have not been shown to cause any damage to the enamel of the tooth. People who use higher concentrations of whitening agents are however advised to use a remineralizing toothpaste during and after whitening.

Tooth sensitivity is a common side-effect of tooth whitening. If tooth sensitivity or gum irritation occur, it is best to start using the whitening product less frequently - say, every other day instead of every day - and reduce the amount of time spent whitening. It is also advised to use a desensitising gel treatment and/or a toothpaste formulated for sensitive teeth. Tooth sensitivity in the majority of cases will cease after 1-4 days or upon termination of the whitening treatment.

When should you not whiten your teeth?

All tooth whitening gel will NOT whiten (nor damage) artificial teeth - crowns, veneers, fillings etc. If you whiten your teeth and you have any of the above in visible areas (such as in the front teeth), the surrounding teeth may become whiter and make the restorations show up more and you may wish to have them replaced.

Tooth whitening should not be used if you suffer from advanced gum disease (gingivitis) or have recently had oral surgery.

Tooth whitening should not be used if you are pregnant or lactating as a precaution. This is because no studies have been carried out to verify it's safety.
