Tooth color is primarily determined by the reflectance of the dentin, modified by the absorption, scattering, and thickness of the enamel Staining can be intrinsic, extrinsic, or both. Charcoal is made from coal, wood, or other substances. It becomes activated charcoal when high temperatures are combined with a gas or activating agent to expand its surface area. This turns it into a powerhouse of porous material that sucks in impurities from the environment around it. Adsorption is different than absorption. Basically, it means that the porous surface of activated charcoal attracts (mostly unwanted) material a bit like a magnet and holds it in its pores. This leaves the area around it clean. Activated charcoal is being touted as a potent natural treatment used to trap toxins and chemicals. American Dental Association warns that activated charcoal is too abrasive and will wear away your tooth enamel. Once the enamel is gone, it's gone forever. The layer beneath, known as the dentin, becomes more visible. Dentin has a natural yellow tinge, meaning that you're likely to be left with teeth that look more yellow or stained than they did to begin with. So the accurate dose on with activated charcoal toothpaste.
