In order to treat deep stains, teeth whitening agents penetrate the surface of your enamel and expose the dentin layer. The dentin layer houses living tissue and nerves inside of your teeth. Upon exposure to these bleaching agents, it’s not uncommon to experience some mild discomfort and sensitivity.
Fortunately, this sensitivity tends to go away on its own within three days. ZOOM2! teeth whitening reduces post-whitening discomfort, but some minor sensitivity is normal. If you want to manage post-whitening sensitivity, Dr. Agamov recommends following these tips:
Use tooth mousse
Coat your teeth in vitamin E oil
Use toothpaste designed for sensitive teeth and a soft-bristled toothbrush
Avoid ingesting hot and cold foods and drinks for three days after your whitening procedure
Take an over the counter pain reliever
