The cost of teeth whitening at the dentist can vary depending on several factors, including the location of the dental practice, the type of treatment used, and the extent of staining or discoloration on your teeth. On average, a professional teeth whitening treatment can range from $300 to $1,500.

In-office teeth whitening treatments are typically more expensive than at-home treatments because they use stronger bleaching agents and specialized techniques to achieve faster and more dramatic results. The price of in-office treatments can also vary depending on the technology used by the dental practice and the level of expertise of the dental professional performing the treatment.

It's important to note that some dental insurance plans may provide coverage for teeth whitening if it is deemed medically necessary, such as in cases where discoloration is caused by a medical condition or prescription medication. However, cosmetic teeth whitening treatments are generally considered elective and are not covered by insurance.

If you are considering professional teeth whitening, it's recommended to consult with your dentist to discuss your options and get an estimate of the cost based on your specific needs and circumstances. Your dental provider can also provide guidance on financing options or payment plans to help make treatment more affordable.
