✅ Introduction
Antibiotics are essential in the management of odontogenic infections; however, their overuse and misuse have accelerated bacterial resistance. Studies indicate that up to 30–50% of antibiotics prescribed in dental practice are unnecessary (Palmer et al., 2021). This inappropriate use promotes the emergence of resistant bacterial strains, reducing therapeutic success and increasing public health risks.
The responsible prescription of antibiotics is not only a therapeutic act but also an ethical duty for dental professionals.

In comparison, the metabolism of a drug in a child is different from that of an adult, so the administration of an antibiotic should be taking into account the diagnosis, age and weight of the pediatric patient.

✅ Definition of Antibiotic Resistance
Antibiotic resistance refers to the ability of microorganisms to survive or grow despite exposure to an antibiotic that would normally inhibit or kill them. Resistance may be intrinsic or acquired through mutation or gene transfer. In dentistry, resistant pathogens such as Streptococcus viridans, Prevotella intermedia, and Staphylococcus aureus have been identified, complicating infection control and leading to treatment failure.

✅ Causes of Antibiotic Resistance in Dentistry

1. Overprescription of antibiotics for non-bacterial conditions (e.g., pulpitis or localized abscesses without systemic signs).
2. Incorrect dosage or duration, allowing bacteria to adapt and survive.
3. Use of broad-spectrum antibiotics when narrow-spectrum agents are sufficient.
4. Patient noncompliance, such as premature discontinuation of therapy.
5. Self-medication or leftover antibiotic use without professional supervision.

✅ How to Prevent Antibiotic Resistance
To reduce the emergence of resistance, dentists must apply antimicrobial stewardship principles, which include:

▪️ Prescribing only when clinically indicated (presence of systemic signs like fever, lymphadenopathy, cellulitis).
▪️ Selecting the narrowest effective antibiotic, targeting the most likely pathogens.
▪️ Limiting duration to the shortest effective course (usually 3–5 days).
▪️ Avoiding routine prophylactic use, except in immunocompromised or high-risk patients (e.g., infective endocarditis prevention).
▪️ Educating patients about adherence and the dangers of self-medication.

Dentists should also remain updated through clinical guidelines from professional associations such as the American Dental Association (ADA) and the World Health Organization (WHO).

📌 Recommended Article :

PDF 🔽 Guideline on use of antibiotic therapy for pediatric dental patients ... The use of antibiotic prophylaxis for dental patients at risk for infection is addressed in a separate best practices document. Information regarding commonly prescribed antibiotics can be found in Useful Medications for Oral Conditions.

✅ How to Choose the Right Antibiotic in Dentistry
The antibiotic choice depends on the type and severity of infection, patient’s medical history, and bacterial profile. Key principles include:

1. First-line antibiotics for most dental infections: Amoxicillin or Penicillin V.
2. Clindamycin for patients allergic to penicillin.
3. Metronidazole for anaerobic infections or combined therapy.
4. Azithromycin for patients with gastrointestinal intolerance to penicillin.

Combination therapy (e.g., Amoxicillin + Clavulanic acid) is recommended for severe infections or cases of β-lactamase–producing bacteria.

📊 Comparative Table: Common Antibiotics and Their Dental Indications

Antibiotic	Indicated Infections	Limitations
Amoxicillin	Odontogenic infections, periapical abscess, cellulitis.	Ineffective against β-lactamase–producing bacteria.
Amoxicillin-Clavulanic Acid	Severe or recurrent infections, mixed aerobic/anaerobic flora.	Possible gastrointestinal upset; higher cost.
Clindamycin	Penicillin-allergic patients, bone infections, anaerobic infections.	Risk of pseudomembranous colitis (C. difficile).
Metronidazole	Necrotizing gingivitis, periodontitis, and anaerobic infections.	Only active against anaerobes; avoid alcohol consumption.
Azithromycin	Alternative for penicillin-allergic patients; soft tissue infections.	May cause QT prolongation; bacterial resistance increasing.

💬 Discussion
Recent data emphasize that antibiotic resistance in dental practice mirrors the global trend seen in medicine. Overreliance on broad-spectrum agents, particularly amoxicillin-clavulanate and azithromycin, contributes to resistance development.
The implementation of antibiotic stewardship programs within dental settings can drastically reduce inappropriate prescriptions. Studies by Cope et al. (2019) and Thompson et al. (2023) demonstrated that educational interventions reduce unnecessary antibiotic use by up to 60% among general dental practitioners.

✍️ Conclusion
Antibiotic resistance in dentistry is preventable through responsible prescribing and adherence to evidence-based protocols. Choosing the correct antibiotic requires evaluating clinical signs, pathogen profile, and patient-specific factors. The goal is to treat infection effectively while minimizing the emergence of resistant strains.

PDF 🔽 Dental pain in pediatric dentistry - Assessment tools ... Dental pain interferes with the patient's quality of life, and is usually caused by caries, but can also be caused by trauma. The control of dental pain in pediatric dentistry is considered a challenge for the operator.

✅ Definition of Acute Infections
Acute dental infections are characterized by sudden onset, rapid progression, and short duration, typically involving bacterial invasion of dental or periodontal tissues. They are usually caused by polymicrobial flora dominated by Streptococcus spp., Prevotella, and Fusobacterium species. Clinically, they manifest as pain, swelling, erythema, and occasionally systemic symptoms such as fever or lymphadenopathy.

✅ Mechanisms of Action of Antibiotics in Dentistry
Antibiotics used in pediatric dental practice act via specific mechanisms targeting bacterial survival and replication:

▪️ β-lactams (e.g., amoxicillin, penicillin V): Inhibit bacterial cell wall synthesis, leading to lysis.
▪️ Macrolides (e.g., azithromycin, erythromycin): Inhibit protein synthesis by binding to the 50S ribosomal subunit.
▪️ Clindamycin: Blocks peptide bond formation at the 50S ribosomal site; effective against anaerobes.
▪️ Metronidazole: Disrupts bacterial DNA synthesis in anaerobic organisms.

Understanding these mechanisms is key to selecting the appropriate antibiotic based on infection type and microbial profile.

✅ Common Acute Infections in Pediatric Dentistry

1. Acute Apical Abscess: Localized pus accumulation due to pulp necrosis and bacterial invasion of periapical tissues.
2. Cellulitis: Diffuse bacterial infection extending through soft tissues; requires immediate antibiotic therapy.
3. Pericoronitis: Inflammation of soft tissue around erupting teeth, especially mandibular molars.
4. Periodontal Abscess: Rapid destruction of periodontal ligament and alveolar bone caused by anaerobic bacteria.
5. Postoperative Infections: Following dental extraction or trauma, often involving mixed aerobic-anaerobic flora.

Prompt identification and antibiotic therapy prevent complications such as facial swelling, osteomyelitis, and systemic spread.

✅ Updated Protocols for Antibiotic Therapy
Current guidelines from the American Academy of Pediatric Dentistry (AAPD, 2024) and British National Formulary for Children (BNFc) recommend:

▪️ Use antibiotics only when infection has systemic involvement or spread beyond local tissue.
▪️ Avoid prophylactic or empirical antibiotic use without clinical indication.
▪️ Prefer narrow-spectrum antibiotics such as amoxicillin for first-line therapy.
▪️ Consider allergy alternatives like clindamycin or azithromycin.
▪️ Adjust dosing by weight and infection severity.

✅ Indications: Which children need antibiotic prophylaxis?
AP is reasonable in pediatric patients with high-risk cardiac conditions undergoing invasive dental procedures:

° Prosthetic cardiac valves or prosthetic material for valve repair.
° Previous history of IE.
° Certain congenital heart diseases: unrepaired cyanotic CHD, CHD repaired with prosthetic material (first 6 months), or repaired CHD with residual defects.
° Cardiac transplant with valvulopathy.

AP is not recommended for other congenital heart conditions, for non-invasive dental procedures, or routinely for prosthetic joints.

📌 Recommended Article :

PDF 🔽 Antimicrobial therapies for odontogenic infections in children and adolescents ... We share a literature review that establishes guidelines for antimicrobial therapy in infections of odontogenic origin and clinical recommendations.

✅ Dental procedures requiring AP

° Yes: procedures involving gingival manipulation, periapical region, or oral mucosa perforation.
° No: anesthesia in non-infected tissue, dental radiographs, orthodontic appliance placement/adjustment, shedding of primary teeth, trauma to lips/mucosa.

✅ Pediatric antibiotic regimens (single dose, 30–60 min before procedure)

Scenario	Antibiotic (Route)	Pediatric Dose	Max Dose	Timing	PK/PD Notes
First-line regimen	Amoxicillin (PO)	50 mg/kg	2 g	30–60 min before	β-lactam; time-dependent (T>MIC). Renal elimination.
Unable to take PO	Ampicillin (IM/IV)	50 mg/kg	—	30–60 min before	β-lactam; T>MIC. Renal elimination.
Unable to take PO	Cefazolin or Ceftriaxone (IM/IV)	50 mg/kg	—	30–60 min before	Cephalosporins; T>MIC. Avoid in penicillin anaphylaxis.
Penicillin/ampicillin allergy (non-anaphylaxis)	Cephalexin (PO)	50 mg/kg	—	30–60 min before	Safe only if no history of anaphylaxis/angioedema.
Penicillin/ampicillin allergy	Azithromycin or Clarithromycin (PO)	15 mg/kg	Azithro: 500 mg	30–60 min before	Macrolides; AUC/MIC. Clarithro: CYP3A4 interactions.
Penicillin allergy (alternative)	Doxycycline (PO)	<45 kg: 2.2 mg/kg; ≥45 kg: 100 mg	—	30–60 min before	Tetracycline; short use usually safe in children.

PDF 🔽 Pharmacological treatment of oral infections in pediatric dentistry - Recommendations and dose calculation ... In comparison, the metabolism of a drug in a child is different from that of an adult, so the administration of an antibiotic should be taking into account the diagnosis, age and weight of the pediatric patient.

✅ Pharmacodynamics and pharmacokinetics

° β-lactams (amoxicillin, ampicillin, cephalosporins): bactericidal, time-dependent (T>MIC). Short half-life, renal elimination.
° Macrolides (azithromycin, clarithromycin): concentration-time dependent (AUC/MIC); azithromycin has a long half-life, clarithromycin is metabolized via CYP3A4.
° Doxycycline: broad distribution, concentration-dependent; short-course use does not cause permanent tooth staining.

✅ Practical considerations and stewardship

° Avoid clindamycin due to C. difficile risk.
° Avoid cephalosporins if prior anaphylaxis to penicillin.
° Do not prescribe AP for routine dental care or orthodontics.
° Delay elective procedures if the patient is already on antibiotics.
° Promote antibiotic stewardship: limit use, educate parents, and prioritize oral hygiene.

Choosing between amoxicillin and clindamycin in pediatric dentistry requires a clear understanding of their mechanisms of action, clinical indications, weight-based dosing formulas, and safety profiles.

💬 Discussion
Evidence shows that AP prevents very few cases of IE, while maintaining good oral hygiene and controlling plaque reduce bacteremia more effectively. Current guidelines restrict AP to high-risk children undergoing invasive dental procedures. This approach reduces unnecessary antibiotic exposure and the risk of adverse effects.

✍️ Conclusion
Antibiotic prophylaxis in pediatric dentistry is not routine. It is indicated only for children with high cardiac risk undergoing invasive dental procedures. Amoxicillin 50 mg/kg (max 2 g) remains the first-line drug. Alternatives include oral cephalosporins, macrolides, or doxycycline (selected cases), with clindamycin excluded. Integration of antibiotic stewardship principles and collaboration with pediatricians and cardiologists is essential.

Antibiotic Selection in Pediatric Dental Infections: Updated Clinical Criteria for U.S. Dentists

Pediatric dental infections are common in clinical practice and can progress rapidly due to anatomical and immunological factors specific to children. When systemic signs or soft tissue involvement are present, selecting the right antibiotic becomes critical.

📌 Recommended Article :

PDF🔽 Dental pain in pediatric dentistry - Assessment tools ... Clinical and radiographic evaluation is essential to determine the origin of the pain, which may be of dental origin or of the adjacent structures. Currently there are instruments that help us assess dental pain in children.

However, antibiotic prescription in pediatric patients requires careful consideration of the likely pathogens, the child’s age and weight, medical history, drug allergies, and antibiotic pharmacokinetics.

This article outlines the evidence-based criteria for selecting safe and effective antibiotics for pediatric odontogenic infections, in accordance with U.S. clinical guidelines.

✅ When Are Antibiotics Indicated in Pediatric Dentistry?
According to the American Academy of Pediatric Dentistry (AAPD, 2022) and current literature, systemic antibiotics in children should be adjunctive, not primary, to dental treatment (e.g., extraction, pulpectomy, or drainage). Antibiotics are indicated in the following situations:

° Infections with systemic involvement (fever, lymphadenopathy, malaise).
° Spread to soft tissues or fascial spaces (e.g., cellulitis).
° Delayed access to dental treatment.
° Medically compromised or immunosuppressed children.

For localized infections without systemic signs, antibiotics are not recommended (Robertson et al., 2020).

📌 Recommended Article :

PDF🔽 Pharmacological treatment of oral infections in pediatric dentistry - Recommendations and dose calculation ... In comparison, the metabolism of a drug in a child is different from that of an adult, so the administration of an antibiotic should be taking into account the diagnosis, age and weight of the pediatric patient.

✅ Key Criteria for Antibiotic Selection

1. Bacterial Spectrum and Common Pathogens
Most odontogenic infections in children are caused by facultative and anaerobic Gram-positive bacteria, including Streptococcus viridans, Prevotella, and Fusobacterium species. Therefore, antibiotics must provide coverage for both aerobic and anaerobic oral flora.
° First-line therapy: Amoxicillin or Amoxicillin-clavulanate.
° Penicillin allergy: Clindamycin or Azithromycin (with caution).

2. Age and Weight-Based Dosing
Pediatric dosing is weight-dependent and must be calculated accurately to ensure therapeutic efficacy and safety. Liquid oral formulations are preferred in most outpatient scenarios.

3. Safety Profile and Contraindications
Certain antibiotics such as tetracyclines are contraindicated in children under 8 years due to the risk of permanent tooth discoloration. Fluoroquinolones are generally avoided in pediatric patients due to concerns about cartilage and tendon development.

4. Route of Administration and Adherence
The oral route is the first choice for mild to moderate infections. Short treatment durations (5–7 days), pleasant-tasting liquid preparations, and fewer daily doses improve adherence in children. For severe infections with fever or poor oral intake, intravenous antibiotics may be required in a hospital setting.

PDF🔽 Antimicrobial therapies for odontogenic infections in children and adolescents ... We share a literature review that establishes guidelines for antimicrobial therapy in infections of odontogenic origin and clinical recommendations.

💬 Discussion
While antibiotics are essential in managing pediatric dental infections with systemic signs, inappropriate use contributes to antimicrobial resistance, a major global and national health concern. In pediatric dentistry, prescribers must balance effectiveness with safety, keeping in mind the developmental sensitivity of the patient and the limited options available.
The cornerstone of management remains the removal of the infection source through local treatment. When antibiotics are necessary, they must be selected using evidence-based guidelines, adjusted for age and body weight, and monitored for adverse effects. Parental education on dosage compliance is also essential.

✅ What Is Antibiotic Prophylaxis in Pediatric Dentistry?
This involves the preventive administration of antibiotics before invasive dental procedures in children who are at high risk for systemic infections. The aim is to minimize transient bacteremia that could colonize vulnerable tissues, such as the heart valves, particularly in immunocompromised or medically complex pediatric patients.

✅ Mechanism of Action
Antibiotics used for prophylaxis work by eliminating or reducing oral bacteria that can enter the bloodstream during dental procedures. The antibiotic is given 30–60 minutes before treatment to achieve optimal blood levels.

° Amoxicillin inhibits bacterial cell wall synthesis (bactericidal).
° Clindamycin inhibits bacterial protein synthesis (bacteriostatic or bactericidal depending on concentration).
° Macrolides (azithromycin, clarithromycin) also inhibit protein synthesis and are used in penicillin-allergic patients.

° Prosthetic heart valves or materials
° History of infective endocarditis
° Certain congenital heart defects (unrepaired, recently repaired with residual defects, or cyanotic CHD)
° Cardiac transplant recipients with valve disease

2. Immunocompromised Patients
Including those with:
° Cancer undergoing chemotherapy
° Neutropenia
° Organ transplants
° Long-term corticosteroid therapy
° IV bisphosphonate therapy

3. High-Risk Dental Procedures
Prophylaxis is recommended only for invasive procedures such as:
° Tooth extractions
° Periodontal surgery
° Deep scaling and root planing
° Any procedure causing mucosal or gingival bleeding

PDF 🔽 Antibiotics and its use in pediatric dentistry: A review ... Antibiotics are among the most frequently prescribed medication for the treatment as well as prevention of bacterial infection in modern medicine

✅ Recommended Antibiotics and Pediatric Dosing

💬 Discussion
Current research and AHA/AAPD guidelines stress that antibiotic prophylaxis should only be used when clinically indicated. Studies have shown that eliminating routine prophylaxis in low-risk patients did not increase the incidence of infective endocarditis. Misuse or overuse contributes to antibiotic resistance, Clostridioides difficile infection, and other complications.
Dentists must evaluate each child’s medical history and assess whether the risk justifies prophylactic use. Furthermore, educating caregivers on the responsible use of antibiotics is essential to support safe dental practices.

💡 Conclusion
Antibiotic prophylaxis in pediatric dentistry is a valuable tool for preventing severe infections but should be limited to patients with specific high-risk conditions. Updated guidelines from the AHA and AAPD emphasize evidence-based decision-making and individual risk assessment. Dental professionals must stay informed and adhere to standardized protocols to ensure the best outcomes for pediatric patients.

💬 Discussion
Despite clear guidelines, studies reveal frequent antibiotic overprescription in pediatric dentistry. A cross-sectional study by Al-Jundi et al. (2022) indicated that many dentists prescribe antibiotics for non-indicated conditions such as reversible pulpitis, primarily due to parental expectations or time constraints. This inappropriate practice fosters resistance and increases adverse drug reactions, including gastrointestinal issues, allergic reactions, and alterations in the child’s developing microbiome.
Moreover, the COVID-19 pandemic initially led to increased remote consultations and a spike in empirical antibiotic prescriptions, further underscoring the need for robust antimicrobial stewardship programs in dental settings.
Educational interventions, integration of prescribing guidelines into electronic health systems, and continuing professional development can help reduce inappropriate prescribing practices. Collaborative efforts between pediatricians, pharmacists, and pediatric dentists are also essential.

Antibiotic therapy in dentistry is essential for preventing and treating infections resulting from dental procedures.

📌 Recommended Article :

PDF 🔽 Antibiotics and its use in pediatric dentistry: A review ... Antibiotics are commonly used in dentistry for prophylactic as well as for therapeutic purposes. Very often antibiotics are used in unwarranted situations, which may give rise to resistant bacterial strains

Correct selection of antibiotic dosage and regimen not only ensures therapeutic efficacy but also minimizes the risk of developing bacterial resistance and adverse effects.

✅ A. Determining Factors in Antibiotic Selection

1. Identification of the Etiological Agent
Odontogenic infections are often polymicrobial, predominantly involving anaerobic and gram-positive aerobic bacteria. Precise identification of the causative agent allows for the selection of an antibiotic with an appropriate spectrum. However, due to the difficulty in isolating and culturing these microorganisms in daily practice, empirical selection based on local epidemiology and the nature of the infection is common.

2. Antibiotic Spectrum
The chosen antibiotic should be effective against the most common pathogens in odontogenic infections. For example, amoxicillin is effective against a wide range of gram-positive bacteria and some gram-negative ones, while clindamycin is preferred in patients allergic to penicillins due to its activity against anaerobes and gram-positive aerobes.

3. Pharmacokinetics and Pharmacodynamics
Understanding the absorption, distribution, metabolism, and excretion of the antibiotic is crucial for determining the dosage and frequency of administration. For instance, amoxicillin has good oral bioavailability and a half-life that allows for administration every 8 hours. Clindamycin, on the other hand, requires administration every 6 to 8 hours due to its shorter half-life.

4. Patient's Condition
The patient's systemic conditions, such as renal or hepatic insufficiency, can affect drug elimination, requiring dosage adjustments. Additionally, in immunocompromised patients, more aggressive or prolonged treatment may be necessary.

5. Possible Interactions and Adverse Effects
It is essential to consider drug interactions, especially in polymedicated patients. For example, erythromycin can interact with other drugs metabolized by the cytochrome P450 system, increasing the risk of toxicity. Moreover, some antibiotics can cause gastrointestinal adverse effects or allergic reactions that must be monitored.

° Adult dosage: 500 mg orally every 8 hours.
° Pediatric dosage: 20–40 mg/kg/day divided into three doses.
° Considerations: In severe infections, the dose may be increased to 1 g every 8 hours. Dosage adjustment is recommended in patients with renal insufficiency.

2. Amoxicillin/Clavulanic Acid
° Indications: Resistant infections or when beta-lactamase-producing bacteria are suspected.
° Adult dosage: 875 mg/125 mg orally every 12 hours.
° Pediatric dosage: 25–45 mg/kg/day divided into two doses.
° Considerations: The combination with clavulanic acid broadens amoxicillin's spectrum but may increase the incidence of gastrointestinal effects.

3. Clindamycin
° Indications: Patients allergic to penicillins; infections by anaerobes.
° Adult dosage: 300 mg orally every 6–8 hours.
° Pediatric dosage: 8–20 mg/kg/day divided into three or four doses.
° Considerations: Monitor for gastrointestinal side effects and the risk of pseudomembranous colitis.

4. Azithromycin
° Indications: Patients allergic to penicillins; infections by susceptible bacteria.
° Adult dosage: 500 mg once daily for three days.
° Pediatric dosage: 10 mg/kg once daily for three days.
° Considerations: Has a prolonged half-life, allowing for simplified dosing regimens.
