Could the sweetness of licorice root help you and your kids fight cavities and gum disease? Yes, according to researchers, who recently isolated several compounds from the herbal extract that have potent antibacterial activity against germs that cause these dental problems.

Licorice is a sweet answer to gum disease

Gum diseases (periodontal diseases) are oral infections that include gingivitis (the milder form) which, left untreated, can develop into periodontitis, which can result in tooth loss. The danger doesn’t end at the mouth, however.

Research has uncovered a connection between heart disease and the main bacteria responsible for periodontal disease. Gum disease is also a complication of diabetes.

Therefore, the estimated 80% of adults in the United States who have gum disease may have more at risk than their teeth and gums. Most of these individuals are not aware they have gum disease, according to the American Dental Hygienists Association, because the condition is painless in its early stages.

Licorice root and gum disease

In a recent study appearing in the American Chemical Society’s Journal of Natural Products, researchers reported they had identified two components in licorice that significantly inhibit the growth of the main bacteria responsible for gum disease and cavities. Both licoricidin and licorisoflavan A were effective against Streptococcus mutans and S. sobrinus, which cause cavities; and Porphyromonas gingivalis and Prevotella intermedia, which have key roles in gum disease.


According to the research team, both of these licorice root extract components could play a role in preventing and treating tooth decay and periodontal disease.
