The process takes about 12-14 days. A- To our knowledge nothing detrimental has been documented and microscopic research shows no changes to the tooth surface. With over a decade of accumulated data to support its position, the American Dental Association (ADA) has come to the conclusion that teeth whitening products with hydrogen peroxide and carbamide peroxide are safe.
A - Results vary.
When wearing the trays at home, Carbamide Peroxide is slowly broken down to Hydrogen Peroxide which whitens the teeth.
The 16% gel whitens more slowly but causes less tooth sensitivity.
The 22% gel whitens quickly but can cause temporary sensitivity to temperatures. Both the l6% and 22% gels need to be worn for about 10-14 days to achieve maximum whiteness.
When whitening your teeth at the dentist office, chairside with a gel activated light system, the teeth will whiten In about an hour.
