Toothpastes containing activated carbon, particularly seen on social networks and on the shelves of many markets, can cause big question marks in the minds of citizens. Experts warn against toothpastes containing black charcoal, which have become popular, although there is speculation as to whether or not they are beneficial. It is stated that the scientific evidence on teeth whitening could not be obtained in the tests carried out on toothpastes containing charcoal and that negative situations may arise.
“NO SCIENTIFIC EVIDENCE ON TEETH WHITENING”
Stating that teeth whitening has a special place for people, the Dean of the Faculty of Dentistry at ESOGÜ, Prof. Dr. Batu Can Yaman, on activated carbon toothpastes, said, “Activated carbon products have now become one of the biggest trends in the world of health and cosmetics. Activated charcoal, the type used in cosmetics and toothpaste; It is a fine-grained powder made from wood, coconut shell, and other natural substances that oxidize under extreme heat. There are few studies evaluating the effectiveness of toothpastes containing activated charcoal. Many pastes containing activated charcoal or activated carbon are sold on websites and in the market under the pretext that they are whiteners. The activated charcoal in toothpaste can help remove surface stains from your teeth. Charcoal is mildly abrasive and can also absorb surface stains to some degree. However, there is no evidence that it has any effect on stains under tooth enamel or that it has a natural whitening effect. Teeth whitening requires work on surface stains as well as internal stains under the enamel. “Although activated charcoal has proven benefits, there is not enough scientific evidence to show that teeth whitening is one of them.”
“HOW THIS AFFECTS IS NOT YET KNOWN”
Claiming that the effect of toothpastes containing activated carbon, which has no proven benefit, on the materials used in the treatment, is not precisely known. Dr. Yaman used the following statements:
“Charcoal toothpaste is too abrasive for everyday use. Using a very abrasive material on your teeth can erode your enamel. It can make your teeth more yellow by exposing dentin, a calcified yellow tissue. It can also make your teeth more sensitive. Also, most charcoal toothpastes do not contain fluoride. Fluoride helps keep tooth enamel strong, which protects your teeth from cavities and decay. Thus, some evidence is emerging that links charcoal-containing toothpaste to increased tooth decay. Although it stains some teeth, charcoal particles can accumulate in the cracks and crevices of old teeth. It is not yet known how charcoal affects the materials used in the manufacture of composite bridges, crowns and fillings. Charcoal particles can accumulate, leaving a black or gray line between them. But when used occasionally after professional cleaning, it can help prevent stains. Although toothpastes containing activated charcoal have received a lot of attention and pressure, they are no more effective than other toothpastes and home whitening products on the market. It may help remove surface stains, but the long-term use of this product is still unknown due to limited studies.
