Yellow tooth discoloration is the most common sign of damaged enamel. This begs the question “Does teeth whitening damage tooth enamel? The answer is no, teeth whitening doesn't damage tooth enamel. While there is no definitive evidence that teeth whitening damages enamel, it is recommended to be careful when undergoing this process. Many over-the-counter and homemade teeth whitening products contain significant amounts of peroxide, which can irritate soft tissues in the mouth if used improperly.
Always read the instructions carefully and follow them carefully when using a teeth whitening product. Abrasive teeth whitening products are generally safe, Dr. Tam said, but rubbing your teeth with particles that are too hard or brushing with abrasive material for longer or more often than recommended can wear out your enamel. Sufficient professional knowledge and advice from your dentist is needed before undergoing any cosmetic dental procedure.
