Analgesics for dental pain: NSAIDs first, opioids last
- Drugs
For most dental pain, ibuprofen with paracetamol works better than opioids. Pain relief buys time; the dentist removes the cause.
What it is
Dental pain is mainly inflammatory, so non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are the most effective single analgesics. Combining an NSAID with paracetamol gives better relief than either alone and than opioid combinations, with fewer adverse effects, according to systematic reviews used by dental associations. Opioids are reserved for severe pain when the combination is contraindicated or insufficient, for the shortest time. Analgesia controls pain while definitive treatment (removing the pulp, draining an abscess, extracting the tooth) is arranged.
What to know
- First line: an NSAID (ibuprofen or naproxen), with paracetamol added if needed.
- NSAID cautions: peptic ulcer or bleeding, kidney disease, heart failure, anticoagulants, late pregnancy, NSAID-sensitive asthma.
- Paracetamol: safe in pregnancy; check total daily intake and liver disease.
- Codeine: variable effect by CYP2D6 genotype; contraindicated in children under twelve and avoided in breastfeeding.
- Opioids for dental pain should be short courses, with advice on safe storage and disposal.
Risks and precautions
- Many people take several products containing paracetamol without knowing; count all sources.
- Placing an aspirin tablet against the gum causes a chemical burn of the mucosa.
- Repeated requests for opioids for dental pain without dental treatment deserve review of the underlying problem and of misuse.
Next step / Initial management
- Offer ibuprofen plus paracetamol if no contraindication; paracetamol alone in pregnancy or when NSAIDs are unsafe.
- Refer to the dentist for definitive treatment; analgesics are a bridge, not the cure.
- Severe pain not controlled with the combination: reassess for spreading infection or another diagnosis before adding an opioid.
Test yourself
Think of the answer, then tap the question to see it.
What analgesic combination works best for most acute dental pain?
An NSAID such as ibuprofen combined with paracetamol.
Why is codeine unreliable and risky?
Its conversion to morphine by CYP2D6 varies; ultrarapid metabolisers can be overdosed and poor metabolisers get little effect.
What happens if an aspirin tablet is held against the gum?
It causes a chemical burn (white, painful necrotic mucosa).
