Condition

Dental Health

Dental health is the condition of your teeth, gums, and the community of microbes in your mouth, and it is linked to more than cavities, including heart disease and diabetes. Among supplements, magnolia bark extract, studied in a sugar-free chewing gum, has trial findings: measures of dental health improved in a randomized trial. The evidence is limited, though, since that result comes from a single trial of 120 people.
