Due to the way of working, water is removed from the teeth, a fact which, in the
case of over-frequent and excessively long exposure, leads to sensitivity.
If the therapy is discontinued, the hypersensitivity disappears again.
Dental decay, leaky (defective) fillings or crowns and exposed dental necks also cause hypersensitivity.
The colour of fillings and dentures already present possibly no
longer matches that of the brightened teeth.
Surplus gel irritates the mucous membranes, as it escapes from the trays and can no longer act on your teeth.
- sensitive teeth
- irritation of mucous membrane
- no brightening of fillings and dentures |
