Your dentist will complete a thorough dental examination of the enamel-staining pattern of your teeth before starting the treatment.

After having covered your gums to protect them from the chemicals, your dentist will apply tooth whitening gel to your teeth.

The scanning laser beam penetrates deep into the stains and detaches the particles from the tooth, even the most stubborn ones ( deep and dark discolorations )
The subsequent selected chemical reaction dissolves the stains without affecting the enamel of the tooth. Laser tooth whitening is a painless procedure and side-effects are almost non-existent ( some patients might experience a temporary sensitivity but this is extremely rare).
