OverviewChildren typically begin to erupt a tooth between the 6th and 8th month of life. Signs of teething are: drooling, irritability, gum swelling and sensitivity, sleeping problems, refusing food, the urge to bite on hard objects and possibly a low grade fever. The discomfort that results from teething is due to the pressure exerted on the tissue in the mouth, called the periodontal membrane, as the teeth erupt.
