“Some toothpaste have abrasive particles, which can remove superficial stains but can damage tooth structure over time. One brand that I recommend is Colgate Optic White because it ranks well on the Toothpaste Abrasive Index and whitens with hydrogen peroxide.”

Also if they contain peroxide for the bleaching action that it has for whitening, it will eventually cause more erosion of the outer layer and hence sensitivity and weakening of tooth structure. Prolonged use can lead to sensitivity which is evident in your case.

Colgate Optic White comes in 7-9% Hydrogen Peroxide, meaning this gel is 2-3x stronger than the leading over-the-counter brands! With Colgate Optic White, you get a faster whitening experience than anything in the stores and at a fraction of the price you would pay at the dentist!

Don't eat or drink for 30 minutes after using a fluoride mouthwash.

Most products recommend that you swish for at least 30 seconds. To get optimal benefits from fluoride mouthwashes, try to avoid drinking, eating or smoking for at least 30 minutes, or you may wash away the fluoride.
