All licensed dentists in the U.S. are allowed to write prescriptions for fluoride, antibiotics and noncontrolled substances used to treat dental-related conditions. To prescribe controlled substances such as Vicodin, Norco and Demerol, dentists must register with the U.S. Drug Enforcement Administration. Dentists can only prescribe medicine to treat dental problems.
Dentists commonly prescribe corticosteroids to alleviate pain caused by tooth and gum problems. Dental anesthetics are prescribed to relieve irritation and pain caused by toothaches, sores in the mouth, dentures or braces. During in-office dental procedures, dentists utilize intravenous sedation, general anesthesia, local anesthesia and nitrous oxide to control pain and reduce anxiety.
