According to a study by Tulane University doctoral candidate Arman Sadeghpour, an extract of cocoa powder was more effective than fluoride in fighting cavities. The extract, a white crystalline powder whose chemical makeup is similar to caffeine’s, helps harden tooth enamel, making patients less susceptible to tooth decay. The extract has been proven effective in the animal model. Sadeghpour said that it will probably be another 2 to 4 years before the product is approved for human use and available for sale.
