Management of Dental Infections and Cellulitis

Introduction to Treatment

The American College of Physicians and the Infectious Diseases Society of America recommend amoxicillin-clavulanic acid (Augmentin) as first-line therapy for acute dentoalveolar abscesses with associated cellulitis, typically administered for 5 days 3
For dental infections with associated cellulitis, amoxicillin-clavulanic acid (Augmentin) is the first-line treatment, with doxycycline as an appropriate alternative for penicillin-allergic patients or as part of combination therapy when MRSA coverage is needed 1, 2

Surgical drainage remains the primary intervention for dental abscesses, with antibiotics serving as adjunctive therapy 3
For infections extending into facial tissues, more aggressive treatment is necessary, similar to management of necrotizing fasciitis 3
Adjunctive antibiotics are particularly indicated for dental infections in medically compromised patients, patients with systemic involvement, and patients with progressive infections or diffuse swelling 3

For non-purulent cellulitis, amoxicillin-clavulanic acid provides excellent coverage against the typical polymicrobial flora 1, 2
Doxycycline is an appropriate alternative in penicillin-allergic patients 2
For purulent cellulitis or when MRSA is suspected, options include doxycycline alone or combination therapy with doxycycline plus amoxicillin 2

A 5-day course of antimicrobial therapy is as effective as a 10-day course if clinical improvement occurs by day 5 2
Duration should be guided by clinical response, with most cases resolving within 5-10 days 2, 4
Clinical improvement should be evident within 48-72 hours of initiating appropriate therapy 2
If no improvement or worsening occurs, reevaluate for need for surgical intervention, resistant organisms, or deeper space infection requiring imaging and possible specialist referral 1, 2, 3

Amoxicillin-clavulanic acid: 500 mg three times daily for 5-7 days 3
Doxycycline: 100 mg twice daily (after loading dose of 200 mg on day 1) for 5-7 days 2, 4
Doxycycline should be avoided in pregnant women and children under 8 years due to risk of dental staining 2
Consider local resistance patterns when selecting empiric therapy 4
