Garlic is believed to ward off vampires – at least in folklore. But even Dracula would love garlic’s oral health benefits.

Allicin, the same sulfur compound that makes breath smell bad after someone eats garlic, helps kill harmful bacteria that cause plaque buildup and gum disease. Dr. Luz Mendoza, program manager of public health sciences at Texas A&M University College of Dentistry in Dallas, said allicin, released when garlic is chopped, crushed or chewed, inactivates essential metabolic enzymes in bacteria and interferes with its ability to form biofilm that leads to oral diseases.

“You probably won’t invite many kisses immediately after eating garlic because of the smell, but your smile will show off the lasting effects,” she said. “Brush your teeth 30 minutes or so after eating.”

The dental benefits don’t end there. Garlic and allicin have anti-inflammatory properties that help reduce gum irritation and swelling. The antibacterial compounds are effective against oral pathogens linked to tooth decay and periodontal disease.

“While garlic shows promise in supporting oral health, nothing replaces regular dental care,” Mendoza said. “Twice-a-year dental checkups and professional cleanings remain essential. If you experience lingering tooth pain or gum problems, schedule an appointment with your dentist for proper diagnosis and treatment.”

Adding fresh garlic to meals supports both overall health and oral health, Mendoza said. Remember to brush afterward.
