The short answer
There is no single best antibiotic for every tooth infection; a dentist decides whether an antibiotic is needed and selects it with drainage or dental treatment when indicated.
What causes most local dental infections?
Most dental infections are local problems caused by bacteria entering the pulp or periodontal tissues. Antibiotics do not remove dead pulp, decay, a blocked abscess, or calculus, so definitive care may require drainage, root canal treatment, extraction, or periodontal treatment.
What should you avoid doing with leftover antibiotics?
Do not use leftover antibiotics or share a prescription. Arrange dental assessment, follow prescribed directions exactly if an antibiotic is indicated, and tell the clinician about allergies, pregnancy, kidney or liver disease, and current medicines.
When can a dental infection become an emergency?
Seek emergency care for facial or neck swelling, fever with worsening illness, difficulty swallowing or breathing, confusion, or inability to open the mouth. Urgent dental care is needed for severe tooth pain, pus, or swelling even when an antibiotic may be prescribed.
What should you ask about antibiotics and dental treatment?
Ask whether drainage or a dental procedure is the main treatment and why an antibiotic is or is not indicated. Ask about allergy precautions, interactions, side effects, the review plan, and what symptoms mean the infection is spreading.
