Pain Reliever of Choice for Toothache in Pediatrics
For pediatric toothache, ibuprofen is the preferred first-line analgesic due to its superior efficacy and longer duration of action compared to acetaminophen, with dosing of 5-10 mg/kg every 6-8 hours. 1, 2
Primary Recommendation: Ibuprofen as First-Line
Ibuprofen (5-10 mg/kg every 6-8 hours) provides more effective pain relief than acetaminophen for dental pain in children, with the added benefit of anti-inflammatory properties that address the underlying inflammatory component of toothache 1, 2
Ibuprofen demonstrates superior antipyretic efficacy at 2,4, and 6 hours post-treatment compared to acetaminophen, which translates to better overall symptom control when fever accompanies dental pain 2
The longer dosing interval (every 6-8 hours versus every 4 hours for acetaminophen) improves compliance and provides more consistent analgesia throughout the day 1
Alternative Option: Acetaminophen
Acetaminophen (10-15 mg/kg every 4 hours) is an acceptable alternative when NSAIDs are contraindicated or unavailable, though it provides comparable but not superior analgesia to ibuprofen 3, 2
Acetaminophen has the advantage of no effects on renal or gastrointestinal function, making it safer in children with specific comorbidities 4
Single doses should be in the range of 10-15 mg/kg at 4-hour intervals to maintain therapeutic levels 5
Combination Therapy for Severe Pain
For moderate to severe toothache, combining ibuprofen with acetaminophen provides enhanced analgesia through complementary mechanisms of action 3
The combination reduces the need for opioid rescue medications in postoperative dental procedures 3
Administer both medications on a scheduled basis rather than as-needed to maintain consistent serum levels and optimize pain control 3
Topical Adjunct for Children ≥2 Years
Benzocaine topical gel can be used as an adjunct for temporary relief in children 2 years and older, applied to the affected area up to 4 times daily 6
Children under 12 years should be supervised during application, and those under 2 years require consultation with a dentist or physician before use 6
Critical Safety Considerations
Both ibuprofen and acetaminophen have comparable safety profiles when used at appropriate doses, with no significant difference in minor or major adverse events 2
However, acetaminophen overdose is reached earlier, is more severe, and is more difficult to manage compared to ibuprofen overdose 1
Avoid exceeding maximum daily doses: ibuprofen 40 mg/kg/day (maximum 1200 mg/day) and acetaminophen 75 mg/kg/day (maximum 4000 mg/day) 5, 1
Common Pitfalls to Avoid
Do not underdose based on age-based schedules that fail to account for weight - always calculate doses using mg/kg to ensure therapeutic levels 5
Do not assume alternating ibuprofen and acetaminophen is always necessary for simple toothache - monotherapy with ibuprofen is often sufficient 1, 2
Do not delay dental evaluation - analgesics provide symptomatic relief but do not address the underlying dental pathology requiring definitive treatment 3
