The American Dental Association has not found any evidence that charcoal toothpaste is safe or effective, and it may actually harm the teeth and gums. Charcoal toothpaste is advertised as a whitening agent that can remove particles from the teeth, but this is a misleading claim.

One paper published in 2019 found that charcoal toothpaste can whiten teeth within 4 weeks of use, but it wasn’t as effective as other whitening toothpastes. Research has found that activated charcoal can be abrasive on teeth and tooth-colored restorations, leading to loss of tooth structure.

There has been a fair amount of anecdotal evidence suggesting that activated charcoal could whiten teeth, but no studies have shown this to be accurate. In fact, many dental experts warn that the substance can be harmful to your teeth.

The Benefits of Charcoal Toothpaste The charcoal helps to whiten the teeth. It is antiviral and antifungal. It can help to ‘absorb’ some of the bacteria that cause bad breath. It removes surface stains without damaging the teeth enamel.

The main danger with using charcoal to whiten your teeth is that it’s a very abrasive substance. The grittiness it provides does remove surface stains and plaque from your teeth, but it’s so harsh that it also wears away the top layer of the tooth, called the enamel.

Medical Definition of dentifrice : a powder, paste, or liquid for cleaning the teeth

Dentifrice is also the French word for toothpaste. Toothpaste is a dentifrice used in conjunction with a toothbrush to help maintain oral hygiene.

Pliny the Elder reported the use of pounded pumice as a dentifrice. Arguably the best-known mention of tooth care among the Romans is found in a letter by Apuleius, who complains that using tooth powder is nothing to be ashamed of, especially compared to the “utterly repulsive things they do in Spain .”
