From the Research

A dental abscess should be treated with antibiotics for 3-5 days, as this duration has been shown to be as effective as longer courses in some cases, according to the most recent and highest quality study available 1. The treatment of a dental abscess typically involves a combination of antibiotics and dental intervention to remove the source of infection.

  • The most common antibiotics prescribed are amoxicillin (500mg three times daily), penicillin VK (500mg four times daily), or clindamycin (300mg four times daily) for those with penicillin allergies.
  • However, antibiotics alone are not sufficient treatment, and definitive treatment requires dental intervention, either through root canal therapy, tooth extraction, or incision and drainage of the abscess.
  • Pain management with over-the-counter medications like ibuprofen (400-600mg every 6 hours) or acetaminophen (500-1000mg every 6 hours) can help with discomfort.
  • Warm salt water rinses (1/2 teaspoon salt in 8 ounces warm water) several times daily can also provide relief. It's essential to note that the ideal duration of antibiotic treatment may vary depending on the individual case and the severity of the infection, and the decision to prescribe antibiotics should be based on a thorough evaluation of the patient's condition, as highlighted in studies such as 2, 3, 4, and 5.
  • These studies emphasize the importance of proper diagnosis, treatment, and management of dental abscesses to prevent complications and improve patient outcomes.
  • Additionally, the choice of antibiotic should be guided by considerations of safety and efficacy, with amoxicillin being a commonly recommended option due to its favorable safety profile, as noted in 5.
