From the FDA Drug Label

In Adults, 750 to 1750 mg/day in divided doses every 8 to 12 hours

  • The recommended dose of amoxicillin for an adult male with a dental abscess is not explicitly stated in the drug label.
  • However, based on the general dosing information for adults, a dose of 750 to 1750 mg/day in divided doses every 8 to 12 hours can be considered.
  • It is essential to note that the drug label does not provide specific dosing recommendations for dental abscesses, and the decision to use amoxicillin for this condition should be made by a healthcare professional 1.

From the Research

For a dental abscess in an adult male, the most recent and highest quality evidence suggests that antibiotics may not be necessary in most cases, and the primary treatment should be definitive dental treatment, such as incision and drainage, as highlighted in the study by 2. When considering antibiotic treatment, the typical amoxicillin dosage is 500 mg taken orally three times daily (every 8 hours) for 5-7 days, as seen in various studies, including 3 and 4. However, it's essential to note that the use of antibiotics should be reserved for cases with systemic involvement or a high risk of progression to systemic involvement, as recommended by 2 and 5. In cases where antibiotics are necessary, amoxicillin works by inhibiting bacterial cell wall synthesis, effectively killing the bacteria causing the infection. While taking antibiotics, patients should also seek definitive dental treatment as antibiotics alone won't completely resolve the underlying dental issue. If the patient has a penicillin allergy, alternative antibiotics like clindamycin (300-450 mg four times daily) should be used instead, as mentioned in 6. Pain management with over-the-counter analgesics such as ibuprofen or acetaminophen is also recommended. Patients should stay well-hydrated and contact their healthcare provider if symptoms worsen or don't improve within 2-3 days of starting antibiotics. Some key points to consider when treating a dental abscess include:

  • Definitive dental treatment, such as incision and drainage, is the primary treatment
  • Antibiotics may not be necessary in most cases
  • Amoxicillin is a common antibiotic used to treat dental abscesses
  • Alternative antibiotics, such as clindamycin, can be used in cases of penicillin allergy
  • Pain management and hydration are essential components of treatment.
