Treatment for Gum Infections

Surgical intervention—not antibiotics—is the first-line treatment for gum infections, including drainage, root canal therapy for salvageable teeth, or extraction for non-restorable teeth. 1, 2

Primary Treatment Approach

The cornerstone of managing gum infections is mechanical removal of the infection source:

  • Perform immediate surgical drainage for accessible abscesses through incision and drainage 1, 2
  • Root canal therapy should be performed for teeth that are salvageable and periodontally sound 1, 2
  • Extract non-restorable teeth when extensive caries, severe crown destruction, or structural compromise prevents adequate restoration 1
  • Scaling and root planing is essential for periodontal infections to remove bacterial biofilm and calculus 2, 3

Critical pitfall to avoid: Prescribing antibiotics without surgical intervention is ineffective and contributes to antibiotic resistance—antibiotics do not eliminate the source of infection 1, 2

When Antibiotics Are Indicated

Antibiotics should be added to surgical management only in specific circumstances:

Systemic Involvement

  • Prescribe antibiotics when fever, malaise, or lymphadenopathy is present 1, 2
  • First-choice antibiotic: Amoxicillin 500mg three times daily for 5 days for acute dentoalveolar abscesses with systemic symptoms 2
  • Alternative for penicillin allergy: Clindamycin 2, 4

Other Indications for Antibiotics

  • Medically compromised patients (immunosuppressed, metabolic disorders) 1
  • Infections extending into facial spaces or cervicofacial tissues require antibiotic treatment 1, 2
  • Diffuse swelling that cannot be drained effectively 1
  • Failure to respond to surgical treatment alone within 2-3 days 4

Second-Line Antibiotic Regimens

If no improvement occurs within 2-3 days of first-line therapy:

  • Amoxicillin-clavulanate (Augmentin) 4
  • Cefuroxime 4
  • Penicillin plus metronidazole 4

Treatment Algorithm for Periodontal Disease

Gingivitis (Reversible Gum Inflammation)

  • Professionally administered plaque control significantly improves gingival inflammation 5
  • Brush teeth twice daily for at least 2 minutes with fluoridated toothpaste 6, 5
  • Use interdental brushes once daily for interproximal plaque removal (flossing only where interdental brushes won't fit) 5
  • Rechargeable power toothbrushes provide additional reductions in gingival inflammation 5
  • Chlorhexidine gluconate 0.12% oral rinse can be used as adjunctive chemical plaque control between dental visits 7, 5

Periodontitis (Irreversible Bone Loss)

  • Initial non-surgical therapy: scaling and root planing with home care review 3
  • Periodontal re-evaluation to identify residual sites with active disease 3
  • Regenerative or resective surgical therapy for sites that don't respond to initial treatment 3
  • Systemic antibiotics are only infrequently indicated and must always accompany mechanical debridement 4
  • Periodontal maintenance therapy at regular intervals is crucial for long-term success 3

Necrotizing Ulcerative Gingivitis

  • Metronidazole or amoxicillin-clavulanate are appropriate choices 4
  • Surgical debridement remains essential 4

Special Considerations

  • Dental evaluation should occur after cardiac stabilization but early enough that invasive procedures can be completed during IV antibiotic therapy for patients with infective endocarditis 6
  • Full series of intraoral radiographs is required to identify caries, periodontal bone loss, and tooth fractures not evident on physical examination 6, 1
  • Denture-related infections may require thorough disinfection of the denture (soak for 10 minutes in chlorhexidine 0.2%) 6
  • Poor oral hygiene and periodontal diseases—not dental procedures—are responsible for the vast majority of oral infections 6

Preventive Measures

  • Dental visits every 6 months for patients with ongoing oral manifestations 6
  • Daily inspection of oral mucosa 6
  • Soft toothbrush after meals and before sleep (replace monthly) 6
  • Alcohol-free mouthwash at least four times daily after brushing 6
  • Avoid smoking, alcohol, and irritating foods (tomatoes, citrus, hot/spicy foods) 6
