What is the best tooth whitening product for thin sensitive teeth from grinding?

Whitening: Teeth that are thin from a bruxism or "grinding" habit are often too sensitive to whiten. There is no one product that is preferred or recommended for such teeth. I would definitely recommend a lower strength bleach (possibly an over-the-counter system) to attempt bleaching. I would definitely discuss your grinding habit with your dentist. This is a condition that needs to be addressed.

Luma White: The in-office professional whitening product, luma white is the system that causes the least amount of sensitivity. It uses an led light which generates no heat ) and takes 32 minutes (8 minutes four times) to complete.

See dentist: Before whitening your teeth, they should be checked by your dentist. Your teeth might need to be restored to preserve the remaining tooth structure and it also may eliminate your sensitivity.

Teeth whitening: You can use over the counter tooth paste or crest 3D whitening strips or pens. However, they are not so effective and/or stable. A professional teeth whitening followed by home whitening system with custom trays for the long term effect. You will be very happy with the results.
