The short answer
A gum or tooth infection usually needs dental treatment to remove the source, while an antibiotic may be considered when infection is spreading or causing systemic illness rather than as a substitute for drainage or tooth treatment.

What is the direct answer?
What does this question mean?
Bacteria can enter a cavity, a crack, the pulp, a gum pocket, or tissue around a partly erupted tooth. The resulting abscess contains inflammatory fluid, and antibiotics alone may not eliminate infected tissue or a blocked drainage pathway.
What can you do next?
Arrange prompt dental assessment for pain, swelling, a bad taste, pus, or a loose tooth. Treatment may include cleaning a gum pocket, draining an abscess, filling decay, root canal treatment, extraction, and an antibiotic when the clinical findings warrant it.
When should you seek dental care?
Urgent care is needed for facial or neck swelling, fever, rapidly worsening symptoms, difficulty opening the mouth, swallowing, or breathing. Do not use leftover antibiotics or stop a prescribed course without contacting the prescriber.
What should you ask the dentist?
Where is the infection, does it need drainage or tooth treatment, and what findings make an antibiotic appropriate in my case?
