TO BE PREGNANT
Teeth whitening during pregnancy is strongly discouraged. Not all adverse effects on the child are known.
It is known that the peroxide used in the whitening treatment accelerates and amplifies the harmful and carcinogenic effects of cigarettes. It is therefore prohibited to smoke during the treatment period.
EATING HIGHLY COLORED FOODS
During the treatment, colored foods can stain your teeth permanently. The best advise is to wear expensive white clothe during the 12 days of treatment. Anything you eat that can ruin your beautiful white shirt, will stain your teeth permantly.
