Teeth whitening is an aesthetic dental procedure that lightens the shades of teeth by application of hydrogen peroxide or carbamide peroxide. In general, teeth whitening can be achieved in dental office or at home.
The in-office whitening gel has higher concentration of peroxides and provides a faster, more prominent whitening effect compared to the one used in home-whitening kit.
Teeth whitening works well in patients who have extrinsic stains, in other words, teeth stains with coffee, tea, tobacco, etc. However, if you have tetracycline stains, you should consider dental porcelain veneers instead of teeth whitening. Mild sensitivity after teeth whitening is common but manageable. The effects of whitening can last from one to three years depending on the patient’s diet and oral hygiene
