Yes, teeth whitening is generally safe when performed by a dental professional. In-office whitening treatments use safe, FDA-approved bleaching agents that will not harm your teeth when used correctly. However, overuse or improper application of whitening products at home can lead to tooth sensitivity or gum irritation. Always consult with your dentist to ensure you’re using the correct products for your needs.

The longevity of teeth whitening results depends on factors like the type of whitening treatment used, your oral habits, and your diet. Typically, in-office whitening can last anywhere from 6 months to 2 years, but it can vary based on how well you maintain your results. To extend the effects, avoid foods and drinks that stain, such as coffee, red wine, and berries.
