Amoxicillin for Dental Abscess
A dental abscess is an accumulation of pus that forms inside the teeth (periapical abscess) or gums (periodontal abscess). A tooth infection usually results from dental caries, when bacteria infect the center of the tooth (the pulp).
There are two types of dental abscess:
The goal of treatment is to drain the pus and eliminate the infection. The dentist may drain the abscess by an opening made through the tooth or as part of a root canal treatment or tooth extraction (if the abscessed tooth can't be saved).
The dentist may prescribe antibiotic for a few days before a dental procedure. However, an antibiotic will not clear the pus or eliminate the infection until the pus is drained. Antibiotic may be used after draining the pus to help clear any remaining infection and prevent complications.
Amoxicillin is a suitable antibiotic for treating both tooth and gum abscesses 1.
Amoxicillin dosage: 500 mg three times a day for 5 days.
You must see a dentist if you have a dental abscess. Amoxicillin alone, without surgical drainage, may not be effective because of poor penetration into the abscess cavity.
Another antibiotic that is also recommended for tooth infection is co-amoxiclav (amoxicillin with clavulinic acid)2.
Co-Amoxiclav dosage: can be used in doses ranging from 375 mg to 625 mg every 8 hours.
Amoxicillin plus metronidazole
Another option is amoxicillin plus metronidazole. The dose which can be used is 375 mg amoxicillin in combination with 250 mg metronidazole every 8 hours for 7 days3. This combination is particularly effective against Porphyromonas gingivalis, a major cause of periodontitis.
