Combating Antibiotic Resistance in Dentistry: Strategies for Prudent Prescribing and Alternative Therapies for Oral Infections

The escalating threat of antibiotic resistance is a significant concern across all fields of medicine, and dentistry is no exception. The widespread use of antibiotics for treating dental infections contributes to this global problem, potentially rendering these once-lifesaving drugs ineffective. Combating antibiotic resistance in dentistry requires a concerted effort focused on prudent prescribing practices and the exploration of viable alternative therapies for oral infections.

The Scope of Antibiotic Use in Dentistry:

Antibiotics are frequently prescribed in dentistry for a variety of conditions, including acute infections like abscesses and cellulitis, prophylactic measures before certain dental procedures in susceptible patients, and sometimes for non-infectious conditions like pulpal pain. While antibiotics are essential in specific situations, their overuse or inappropriate prescribing contributes to the selection and spread of antibiotic-resistant bacteria within the oral microbiome and beyond.

Strategies for Prudent Antibiotic Prescribing:

• Accurate Diagnosis: Antibiotics should only be prescribed for confirmed bacterial infections, not for viral infections or non-infectious inflammatory conditions. A thorough clinical examination and, when necessary, diagnostic imaging are crucial for accurate diagnosis.
• Targeted Therapy: When antibiotics are indicated, selecting the narrowest-spectrum antibiotic that is likely to be effective against the suspected pathogens is preferred. Culture and sensitivity testing can guide this selection in persistent or severe infections.
• Appropriate Dosage and Duration: Prescribing the correct dosage and duration of antibiotics, based on established guidelines and the severity of the infection, is essential to eradicate the bacteria while minimizing the risk of resistance development. Shorter courses are often sufficient for localized infections.
• Delayed Prescribing: In some cases of mild, localized infections in otherwise healthy individuals, a "wait-and-see" approach with close monitoring and delayed antibiotic prescribing may be appropriate, allowing the body's immune system to resolve the infection.
• Patient Education: Educating patients about the importance of completing the full course of antibiotics as prescribed, even if symptoms improve, and the risks of antibiotic overuse is crucial.
• Adherence to Guidelines: Dentists should stay informed about and adhere to evidence-based antibiotic prescribing guidelines developed by professional organizations and public health agencies.

Exploring Alternative Therapies for Oral Infections:

Reducing reliance on antibiotics requires exploring and implementing effective alternative therapies for managing oral infections:

• Mechanical Debridement: For many localized dental infections, such as periodontal abscesses or pericoronitis, mechanical removal of the infected material (pus, debris, bacteria) through incision and drainage or debridement is often the primary treatment and may be sufficient without antibiotics in some cases.
• Antiseptic Mouthrinses and Topical Agents: Chlorhexidine mouthrinse and other antiseptic agents can help reduce the bacterial load in the oral cavity and may be useful as adjunctive therapy for certain infections. Topical antibiotics or antifungals may be appropriate for localized infections.
• Photodynamic Therapy (PDT): PDT involves the use of a photosensitizing agent and a specific wavelength of light to kill bacteria in localized infections, such as periodontal disease and peri-implantitis.
• Ozone Therapy: Ozone gas or ozonated water has antimicrobial properties and is being explored as a potential adjunctive therapy for various oral infections.
• Probiotics: While more research is needed, oral probiotics may help restore a healthy balance of the oral microbiome and potentially prevent or manage certain infections.
• Natural Antimicrobial Agents: Some natural substances, such as certain essential oils and plant extracts, have demonstrated antimicrobial activity in vitro and are being investigated for their potential role in oral infection management.

A Collaborative Effort:

Combating antibiotic resistance in dentistry requires a collaborative effort involving dentists, patients, researchers, and public health authorities. By embracing prudent prescribing practices, exploring and validating alternative therapies, and educating patients about the responsible use of antibiotics, the dental profession can play a crucial role in preserving the effectiveness of these vital medications for future generations.
