Activated charcoal is an age-old material with various uses. However, it gained recognition at the end of the 20th century and has only grown in popularity since then for teeth whitening.In 1834, an American physician used activated charcoal to save the life of a patient who accidentally ingested mercury chloride. Since then, many safe and effective uses of the substance have been discovered, including using it to brush your teeth.But I
’m not talking about the charcoal that’s commonly used on the barbeque—although they are both made from the same base materials.[u]yongruida activated carbon[/u] Activated charcoal is a finely milled black powder made from coconut shells, bone char, olive pits, coal, sawdust, or other materials. The charcoal is processed with high heat, which
“activates” it. This changes its internal structure, making it more porous than regular charcoal.It’s also processed in this way to rid it of any additional substances that are harmful to humans. It has a chemical composition that makes it a useful substance in a variety of situations. In the past decade teeth whitening has become a global industry. From dental office bleaching treatments to DIY home remedies, the perfect white smile is well sought after.Can activated charcoal safely whiten teeth? There
’s no formal evidence that activated charcoal whitens teeth. However, activated charcoal has been FDA approved for many health uses. The American Dental Association has not currently approved any activated charcoal products for dentistry.
Though, observations suggest that using activated charcoal on your teeth is effective in absorbing plaque and other compounds that stain teeth. Meaning, the chemical properties of activated charcoal is a natural teeth whitener. It doesn
’t neutralize the toxins—it binds to them, resulting in whiter teeth. I want to warn against using charcoal toothpaste that is too abrasive.Since teeth do not regrow or replenish, using a substance that could potentially wear down the enamel may be detrimental. So it
’s important to find a good charcoal toothpaste that isn’t too abrasive.The whitening ability of charcoal exists in its porosity, while the trouble resides in its abrasiveness. Relative Dentin Abrasivity (RDA) is a guide to measure abrasiveness for all FDA approved dental products and the FDA recommends a score of 200 or below.Activated charcoal powder scores about a 70 to 90 on the RDA scale while most whitening toothpastes score between 100 to 200 RDA.Always check the abrasiveness of activated charcoal toothpaste.
