Pain relief after tooth extraction: what the trials found
Compare ibuprofen, acetaminophen, naproxen, and opioid regimens after tooth extraction, with measured pain outcomes, evidence limits, and source links. Every figure below is taken from the cited source — nothing is estimated or interpolated.
Clinically reviewed by Chithra Durgam, DDS on .
+1.68 / 4
greater pain relief at six hours versus placebo for ibuprofen plus acetaminophen after surgical extraction (95% CI 1.06–2.31); this is a mean difference, not a patient pain score [2023]
−0.70 / 10
lower pain score on the first day and night for ibuprofen plus acetaminophen versus hydrocodone plus acetaminophen after impacted third-molar surgery (95% CI −0.94 to −0.45) [2025]
2.9% vs 6.1%
needed rescue analgesia in the nonopioid and opioid groups, respectively, in the same third-molar trial [2025]
56 trials
and 9,095 participants contributed to the six-hour pain-relief network analysis; the enrolled procedures were surgical extractions, mostly third molars [2023]
Analgesics after extraction: outcomes and guidance
Each row names the population, comparison, time point, and source behind its finding. Trial doses identify studied regimens; they are not a patient-specific prescription.
| Regimen or decision | Population and measure | What the evidence found | Interpretation | Source |
|---|---|---|---|---|
| Ibuprofen plus acetaminophen | Surgical extraction; six-hour pain relief versus placebo, scored from 0 to 4 | For the studied single-dose combinations of ibuprofen 200–400 mg and acetaminophen 500–1,000 mg, the mean difference was +1.68 points (95% CI 1.06–2.31; moderate certainty). This is a pooled indirect comparison against placebo, not proof that every combination dose outperforms every alternative dose.Full clinical answer | First-line option | 202320242026 |
| Ibuprofen alone | Surgical extraction; six-hour pain relief versus placebo, scored from 0 to 4 | The fast-acting or acid 400 mg regimen had a mean difference of +1.31 points (95% CI 1.17–1.45; moderate certainty). The ADA includes an NSAID alone among initial options when suitable for the patient.Full clinical answer | First-line option | 20232024 |
| Naproxen sodium alone | Surgical extraction; six-hour pain relief versus placebo, scored from 0 to 4 | The studied 400–440 mg regimen had a mean difference of +1.44 points (95% CI 1.07–1.80). The ADA also includes naproxen among initial NSAID options; the estimate is not a direct comparison with ibuprofen.Full clinical answer | First-line option | 20232024 |
| Acetaminophen alone | When an NSAID is contraindicated or inadvisable | The ADA guideline suggests acetaminophen alone after extraction when an NSAID cannot be used. This is a conditional, low-certainty recommendation, not a claim that acetaminophen matches NSAID pain relief in the six-hour network analysis.Full clinical answer | Alternative | 2024 |
| Ibuprofen plus acetaminophen versus hydrocodone plus acetaminophen | 1,815 adults after impacted mandibular third-molar surgery; 0–10 pain scale over several days | In a direct randomized trial, the nonopioid group reported 0.70 points less pain on the first day and night (95% CI −0.94 to −0.45), and 0.28 points less on the second day and night (95% CI −0.52 to −0.04). Rescue analgesia was used by 2.9% versus 6.1%, respectively. These results apply to the two tested regimens and this procedure, not to all nonopioid and opioid combinations.Full clinical answer | Nonopioid favored | 2025 |
| Other opioid regimens | Surgical extraction; six-hour pain relief versus placebo | In the network analysis, oxycodone 5 mg, codeine 60 mg, and tramadol 37.5 mg with acetaminophen 325 mg were not shown to improve pain relief over placebo. Acetaminophen 650 mg with oxycodone 10 mg did show benefit (+1.19 on the 0–4 scale; 95% CI 0.85–1.54). An absent demonstrated benefit for a tested regimen is not evidence that all opioids are ineffective.Full clinical answer | Regimen-specific | 2023 |
| Rescue opioid decision | After first-line treatment is inadequate or an NSAID cannot be used | The ADA reserves opioids for selected cases when first-line pain control is insufficient or NSAIDs are contraindicated, and advises against routine just-in-case prescribing. This is a clinical decision after reviewing medical history, other medicines, and risks; the comparison table does not supply an automatic escalation rule.Full clinical answer | Selected cases | 20242024 |
How to use this table
- First establish whether the patient can safely take an NSAID. Gastrointestinal bleeding, kidney and cardiovascular risks, other medicines, and relevant medical history can change the choice; acetaminophen also carries liver and duplicate-product risks.
- The network analysis measured short-term relief after surgical extraction, predominantly impacted third molars. Do not apply its effect sizes as if they were established for a simple extraction, long-term dosing, or children under 12.
- The 2025 trial directly compared two specific regimens after impacted mandibular third-molar surgery; it measured pain across days and should not be merged numerically with the network review's six-hour placebo comparisons.
- The ADA guideline covers adolescents aged 12 or older, adults, and older adults after simple or surgical extraction. Its broader recommendation is informed by the evidence, but the adult trial estimates here are not pediatric effect estimates.
- A patient with unexpectedly severe, persistent, or worsening post-extraction pain needs clinical reassessment; an analgesic comparison does not identify the cause.
How this brief was built
The six-hour figures come from a network meta-analysis of randomized trials after surgical extraction and are mean differences versus placebo on a 0–4 pain-relief scale; they are not direct differences between regimens or multi-day outcomes. The separate 2025 head-to-head trial followed adults after impacted mandibular third-molar surgery and measured pain on a 0–10 scale over subsequent days. ADA recommendations are identified as guidance, not trial results. The populations, scales, and time points stay separate so the table does not imply a pooled comparison that was never performed.
