Teeth whitening tooth paste works by bleaching the natural tooth enamel beyond its surface with peroxide based formulations and/or the chemical sodium bicarbonate, that works to remove enamel stains.
Glycerin is also often found in most of the best teeth whitening formulas yet it is not considered dangerous, but is believed to be the chemical behind temporary tooth sensitivity.
The most talked about over the counter teeth whitening procedure and agent systems are: Painted on tooth whiteners, those teeth whitening strips, tray teeth whitening and whitening toothpaste.
