Dr. Lee to Mary: "Give us a big smile and show us those pearly whites. Wow! I think you are going to be pleased with the results. The whitening procedure lightened your teeth by six shades."

Hypersensitivity of the teeth and gingivae are common side effects of teeth bleaching. Using a dentifrice for sensitive teeth relieves the symptoms, which subside in three to five days. Continuing a regular program of proper oral hygiene will help to maintain the result.
