Can a combination of bentonite clay, calcium carbonate, crushed cloves and kaolin clay help heal cavities? No, that's not true: No reliable scientific studies show bentonite clay can cure cavities, according to the American Dental Association. They do not recommend the clay for any dental hygiene practice.
The claim appeared in a video (archived here) on TikTok on July 3, 2023. The video opened with the statement:
In my last video, I told you how to heal small cavities using a combination of bentonite clay, calcium carbonate, crushed cloves and kaolin clay.
Bentonite, which has been mined in Wyoming for over 125 years, has a variety of uses, including cat litter, cosmetics and as a drilling mud for oil and natural gas wells. It can contain high levels of heavy metals.
In 2016, the Food and Drug Administration warned consumers not to use two products containing the clay -- Bentonite Me Baby and Best Bentonite Clay -- because of the potential for lead poisoning.
As opposed to a quick fix, the ADA recommends that people brush their teeth twice a day with a fluoride toothpaste, clean between their teeth once a day and regularly visit their dentist as a way to help prevent tooth decay.
Lead Stories has debunked claims about oral health before. For example, we wrote that oil pulling is not a proven remedy for root canal infections and cavities. Also, we reported that there is no evidence using the herb comfrey as a mouthwash can help heal teeth and gums.
