Recognized as safe by the US Food and Drug Administration, glycerin is a nontoxic ingredient that helps keep products such as toothpaste from drying out. However, some people may have allergies to glycerin. Consult your dentist if you experience an allergic reaction after brushing your teeth with a glycerin toothpaste. You can also try brushing with a non-glycerin toothpaste alternative.
