Simply put, there are two types of teeth stains, extrinsic and intrinsic. Extrinsic stains are those that are on the surface of the tooth, while intrinsic stains are found on the inside of the tooth and show through the enamel as discoloration. While whitening toothpastes and special chewing gums are effective at removing extrinsic stains, the darker more stubborn stains are on the inside. The PEARLY WHITES specially formulated gel has the most effective ingredients to remove intrinsic stains. When the PEARLY WHITES gel is applied to the tooth, it breaks down into water and radical hydroxyl ions. These ions move through the dental tubules and into the tooth where they can attach themselves to stain particles and break down the stains. Once the stains are removed, teeth appear whiter and brighter.
