Localized swelling can come from different dental or periodontal problems. Because infection is one possibility, persistent or worsening swelling should be evaluated.
What to pay attention to
- Look for progression — Increasing swelling or spreading facial swelling deserves prompt attention.
- Note systemic symptoms — Fever or feeling unwell is important to report.
- Do not rely on leftover antibiotics — Appropriate treatment depends on the dental diagnosis.
