From the Guidelines

Azithromycin should not be used as a first-line treatment for tooth infections, and its use is generally not recommended due to the availability of more effective antibiotics and the importance of addressing the underlying dental issue. According to the European Society of Endodontology 1, surgical drainage is key in treating acute apical abscesses, and adjunctive antibiotics are only recommended in specific patient groups, with phenoxymethylpenicillin as the first choice. The American Dental Association 1 also recommends against the use of antibiotics for irreversible pulpitis. For tooth infections, amoxicillin (500 mg three times daily for 7 days) or amoxicillin with clavulanic acid, or clindamycin (300 mg four times daily for 7 days) for penicillin-allergic patients are more commonly prescribed 1. Some key points to consider when treating tooth infections include:

  • Prompt treatment is essential to prevent the spread of infection
  • The underlying dental issue must be addressed through dental procedures
  • Antibiotics should only be used in conjunction with surgical treatment, and only when necessary
  • The choice of antibiotic should be based on the specific patient's needs and medical history. It's worth noting that azithromycin works by inhibiting bacterial protein synthesis, but its spectrum of activity doesn't cover all oral bacteria as effectively as other antibiotics 1.

From the Research

Azithromycin for Tooth Infection

  • Azithromycin is not typically mentioned as a first-line treatment for tooth infections in the provided studies 2, 3, 4.
  • However, one study compared the local antimicrobial and anti-inflammatory effects of azithromycin and amoxicillin before surgical placement of dental implants, and found that azithromycin was available at the surgical site for a longer period of time and exhibited lower levels of proinflammatory cytokines and chemokines 5.
  • The study suggests that azithromycin may be effective in reducing postoperative inflammation, but its use for tooth infections is not well-established 5.
  • Other antibiotics such as penicillin V, amoxicillin, and clindamycin are more commonly recommended for the treatment of odontogenic infections 2, 3, 4.
  • The choice of antibiotic should be based on the severity of the infection, the patient's medical history, and the susceptibility of the causative pathogens to the antibiotic 3, 4.
