Retail stores are filled with teeth whitening
There are two ways to whiten. One is to remove surface stains. Pigments from dark colored foods, beverages, and tobacco become embedded in microscopic pores in tooth enamel. Abrasive toothpaste scrapes some of these pigments away. However, the gritty compound may scratch enamel, worsening the problem in the long term.
The other technique is oxidation. A peroxide based teeth-bleaching agent is applied. A chemical reaction occurs as it comes into contact with air. This creates tiny bubbles that work their way into pores in enamel. As the bubbles burst, they lift stains away and lighten the color of tooth structures.
Is teeth whitening safe? It can be, with the oversight of a dental team. Retail products do not have the same strength as the prescription whitening agent supplied by a dentist. Thus, the temptation is to over-use store products – leaving them on too long or whitening more frequently than recommended. Combined with an ineffective delivery system (messy strips or trays that don’t fit your mouth properly) that can injure soft tissues and cause mouth sensitivity.

Some deep intrinsic discoloration, such as tetracycline staining, will not respond to these more natural teeth whitening options. The dentist may recommend cosmetic bonding, porcelain veneers, or crowns to hide discoloration.
