Medications

Your dentist may prescribe chlorhexidine gluconate (Peridex, Periogard), a prescription mouthwash, to reduce the bacteria that cause tooth decay. He or she may also recommend or prescribe other types of fluoride treatment, such as fluoride mouthwash, toothpaste, or supplements.

Over-the-counter medicine can also relieve pain and swelling in your face and jaw caused by tooth decay. These include acetaminophen, such as Tylenol or Panadol; ibuprofen, such as Advil or Motrin; and aspirin. Do not give aspirin to anyone younger than 20 because of the risk of Reye's syndrome.
