What are the recommended treatments for toothache pain relief?

Management of Toothache Pain Relief

For toothache pain relief, NSAIDs such as ibuprofen are the first-line treatment option, with acetaminophen as an alternative when NSAIDs are contraindicated. 1, 2

First-Line Treatments

Oral Analgesics

• NSAIDs are the preferred first-line treatment for toothache pain due to their anti-inflammatory and analgesic effects 1, 3
  • Ibuprofen: 400-600 mg every 6 hours (maximum 2400 mg daily) 1, 4
  • Naproxen: 375-500 mg twice daily 2
  • Meloxicam: 7.5-15 mg once daily 5
• NSAIDs should be used at the lowest effective dose for the shortest possible time to minimize adverse effects 2
• For mild to moderate pain, acetaminophen (paracetamol) 500-1000 mg every 4-6 hours (maximum 4000 mg daily) can be used when NSAIDs are contraindicated 6, 1

Administration Strategy

• Fixed interval dosing (rather than as-needed) provides better pain control for acute toothache pain 1, 3
• Early treatment at appropriate starting doses is more effective as pain is easier to prevent than treat 1

Second-Line and Combination Treatments

For Moderate to Severe Pain

• Combination therapy with NSAIDs plus acetaminophen provides superior pain relief compared to either medication alone 1, 3
• For severe pain, fixed combinations of NSAIDs with weak opioids may be necessary 1
  • However, NSAIDs + opioid combinations should be used with caution due to potential adverse effects 2

Topical Treatments

• Topical anesthetics can provide temporary relief for accessible toothache pain 7, 2
  • Benzocaine topical preparations for temporary relief of toothache pain 7
  • Lidocaine 2% viscous solution can be applied directly to painful areas 2
  • Topical capsaicin has limited evidence for effectiveness in dental pain 2

Non-Pharmacological Approaches

Local Measures

• Local heat or cold applications can provide temporary relief 2
• Avoiding hot, cold, or sweet foods and beverages that trigger pain 2

Definitive Treatment

• Surgical intervention is the definitive treatment for impacted wisdom teeth causing pain 1
• For dental abscesses, surgical drainage is the key intervention 1

Special Considerations

Risk Assessment

• Evaluate gastrointestinal, renal, and cardiovascular risk factors before prescribing NSAIDs 2, 5
• Consider proton pump inhibitor co-therapy for patients at high risk of GI complications when using NSAIDs 2, 5
• Patients with renal impairment should use NSAIDs with caution and at reduced doses 1

Diagnostic Considerations

• Consider non-odontogenic causes if pain persists despite appropriate dental treatment 8
• Signs of non-odontogenic toothache include inadequate local dental cause, constant unremitting pain, or failure to respond to reasonable dental therapy 8

Treatment Algorithm

1. Mild Pain: Start with ibuprofen 400-600 mg every 6 hours OR acetaminophen 500-1000 mg every 4-6 hours if NSAIDs are contraindicated 1, 3
2. Moderate Pain: Combine NSAIDs with acetaminophen at regular intervals 1, 3
3. Severe Pain: Consider adding a weak opioid or using fixed NSAID-opioid combinations for short-term use only 1, 2
4. Adjunctive Therapy: Add topical anesthetics like benzocaine or lidocaine for temporary relief 7, 2
5. Definitive Treatment: Seek appropriate dental care for the underlying cause 1, 8

Remember that antibiotics are not useful for pain relief in irreversible pulpitis and should only be prescribed when there is evidence of systemic infection 9, 1.
