Stay informed with the latest evidence, systematic reviews, clinical guidelines, and real-world studies on antibiotic resistance, prophylaxis, and rational prescribing in dental practice. Explore expert insights to support safe, effective, and guideline-driven patient care.
Antibiotic resistance (ABR) is a significant global health concern with direct implications for dental practice. Although dentistry accounts for a smaller share of total antibiotic prescriptions, inappropriate prescribing, unnecessary prophylaxis, self-medication, and lack of standardized guidelines contribute substantially to resistance. This leads to reduced treatment efficacy and broader public health risks through the spread of resistant microorganisms. Addressing ABR requires antimicrobial stewardship programs, evidence-based prescribing, improved diagnostics, professional and public education, and context-specific regulatory measures particularly in India to ensure the sustained effectiveness of antibiotics.
Read MoreAntibiotics play an essential role in managing bacterial infections in dental practice; however, their excessive and inappropriate use contributes to the development of antibiotic resistance, a major global public health concern. Resistance diminishes therapeutic efficacy and complicates infection management. Therefore, antibiotic prescribing in dentistry should be strictly guided by evidence-based recommendations, such as those issued by the American Dental Association, to ensure rational and judicious use.
Read MoreProphylactic antimicrobials are widely used before invasive dental procedures, yet their clinical benefit remains uncertain and must be balanced against antimicrobial resistance and microbiome disruption. A PRISMA-guided systematic review identified 10 randomized controlled trials evaluating systemic antibiotics and/or antiseptic prophylaxis versus placebo or no prophylaxis. Random-effects meta-analysis (~1,950 participants) demonstrated no significant reduction in early infectious or bacteremia-related outcomes, including in dental-surgery subgroups, with substantial heterogeneity. Although isolated trials reported reductions in bacteremia surrogates, routine prophylaxis did not consistently improve clinical outcomes or postoperative morbidity. Overall, current evidence does not support routine antimicrobial prophylaxis, emphasizing the need for risk-based prescribing and strengthened antimicrobial stewardship.
Read MoreCephalexin may be prescribed for dental infections in patients with penicillin allergy only if there is no history of severe immediate hypersensitivity reactions (e.g., anaphylaxis, angioedema, or urticaria), as cross-reactivity reported in up to 10% of cases can occur due to structural similarities in β-lactam side chains.
Read MoreCo-amoxiclav (amoxicillin–clavulanic acid) is recommended as first-line therapy for oral abscesses, while amoxicillin alone may be considered in mild cases following adequate surgical drainage. In contrast, sultamicillin is not endorsed by major dental or infectious disease guidelines and lacks robust clinical evidence supporting its use in oral abscess management.
Read MoreCephalexin may be effective in selected cases of oral or periodontal abscesses due to its activity against common odontogenic pathogens. However, it is not considered first-line therapy and does not substitute for definitive dental management, such as incision and drainage or root canal treatment. Its use should be guided by a dentist or physician, as inappropriate prescribing may contribute to antimicrobial resistance and may be ineffective against resistant oral flora.
Read MoreThis interrupted time-series analysis of dental extraction visits (2012–2024) assessed the impact of national guidelines recommending amoxicillin over third-generation cephalosporins for surgical site infection prophylaxis in patients aged ≥75 years. Following the 2014 and 2016 guideline implementations, third-generation cephalosporin use declined significantly, particularly in hospitals with both infection control departments and ward pharmacists, and later in dental clinics. The shift toward amoxicillin was more pronounced in out-of-hospital prescriptions. Surgical site infection rates remained stable, while overall antibiotic costs decreased. These findings demonstrate that guideline-driven antimicrobial stewardship, supported by multidisciplinary collaboration, can reduce broad-spectrum antibiotic use and healthcare costs without compromising patient safety.
Read MoreThis multicenter, retrospective real-world study evaluated the effectiveness and safety of co-amoxiclav in 4,436 adults with dental infections. The mean patient age was 40.23 ± 12.20 years, with undifferentiated dental infections being most common (52%). The predominant regimen was co-amoxiclav 625 mg twice daily for 5–7 days (40.98%), and 95.55% of patients achieved complete symptom resolution within 7 ± 2 days. Significant reductions were observed in C-reactive protein levels, white blood cell counts, and pain scores (p < 0.0001), while treatment-related adverse events were rare (0.16%). These findings support the strong clinical efficacy and favorable safety profile of co-amoxiclav in routine dental infection management.
Read MoreThis cross-sectional survey of 240 dental practitioners in West Bengal (51.2% response rate) evaluated beliefs and prescribing practices related to antibiotic use in dental procedures. Amoxicillin–clavulanic acid was the preferred antibiotic in nonallergic patients (77.6%), while clindamycin was commonly prescribed for allergic individuals (38%). Most practitioners prescribed antibiotics for at least 5 days, with facial swelling being the most frequent indication (34.44%). Although 97.9% demonstrated awareness of antimicrobial resistance, a tendency toward overprescription was identified, potentially contributing to the growing burden of antimicrobial resistance.
Read MoreAntibiotic stewardship is essential to combat antimicrobial resistance, particularly in dentistry and periodontics, where antibiotics are frequently used as adjuncts to mechanical and surgical therapy. Inappropriate selection, overuse, and empirical prescribing contribute to resistance, adverse effects, and disruption of the oral microbiome. Stewardship programs promote evidence-based prescribing through clear clinical indications, surveillance, education, and interdisciplinary collaboration. In periodontal practice, this includes minimizing unnecessary systemic antibiotics, prioritizing local drug delivery when suitable, and considering host-modulation strategies. Strengthening stewardship ensures effective patient care while supporting broader public health efforts to limit antimicrobial resistance.
