Dosage
The typical dose of cephalexin for an adult with a tooth infection is a total of 1-4 grams per day taken in divided doses. Typically, the prescription is written as 250 mg every six hours, or 500 mg every 12 hours. A doctor may prescribe higher doses of cephalexin for tooth and bone infections if the infection is more severe.
