For tooth pain, ibuprofen is generally considered more effective on its own than paracetamol, because most toothache is driven by inflammation around the tooth or gum, and ibuprofen works directly on that inflammation while paracetamol does not. That said, the right choice depends on your individual health, and this article is general information only, not personalised medical advice.
Key Takeaways
- Ibuprofen is an anti-inflammatory, which usually makes it more effective alone for typical dental pain caused by inflammation
- Paracetamol works differently and is a sensible alternative or add-on for people who cannot safely take ibuprofen
- Many dentists suggest taking both together, staggered according to product labelling, since they work via different mechanisms
- Certain groups, including people with stomach, kidney, or heart conditions, and those who are pregnant, should check with a doctor or pharmacist before taking ibuprofen
- Paracetamol is generally considered the first choice pain reliever during pregnancy, but this should always be confirmed with your doctor or pharmacist
- Pain relief only manages symptoms, it does not treat the underlying cause, so a dental check is still needed for ongoing tooth pain
As a general rule, if you are healthy and able to take both medications safely, ibuprofen is usually the more effective single option for dental pain because it targets inflammation directly, while paracetamol is the safer first choice if you cannot take NSAIDs or are pregnant. Always follow the dosing on the product label and check with a pharmacist if you are unsure.
Why tooth pain responds differently to each medication
Most toothache, whether from decay, an abscess, a cracked tooth, or gum inflammation, involves swelling and inflammation of the tissue around the tooth. Ibuprofen belongs to a class of medications called non-steroidal anti-inflammatory drugs, or NSAIDs, which reduce the chemical signals that cause inflammation and pain. Because dental pain is so often inflammatory in nature, ibuprofen tends to provide more targeted relief for it than paracetamol alone.
Paracetamol works through a different mechanism in the brain and body to reduce the perception of pain and lower fever, but it does not have the same anti-inflammatory action. It can still be effective for tooth pain, particularly milder discomfort, and it remains a valuable option for people who cannot take NSAIDs.
Ibuprofen vs paracetamol: general comparison
| Factor | Ibuprofen | Paracetamol |
|---|---|---|
| Type of medication | Anti-inflammatory (NSAID) | Analgesic and fever reducer |
| How it helps toothache | Reduces inflammation that is usually the source of dental pain | Reduces the perception of pain, no direct anti-inflammatory effect |
| Typically suited to | Adults without stomach, kidney, heart, or NSAID-related conditions | People who cannot take NSAIDs, including many pregnant women (check with your doctor) |
| Common cautions | Stomach irritation, kidney impact, interactions with some medications and health conditions | Liver impact at high doses, care needed with other paracetamol-containing products |
| Used together | Often recommended by dentists, staggered per label directions | Often recommended by dentists, staggered per label directions |
This table is general information about how each medication works, not prescribing advice. Always follow the dosing instructions on the product packaging and speak with a pharmacist or doctor about what is appropriate for you.
Why some dentists suggest taking both together
Because ibuprofen and paracetamol work through different pathways in the body, taking both, staggered according to the instructions on each product's label, is a combination some dentists suggest for short-term relief of moderate dental pain in adults who can safely take both. This is general clinical guidance rather than a directive for every situation, and it should be checked against the specific product labels you have at home and your own health history. It is not a substitute for treating the underlying dental problem.
Who should be cautious with ibuprofen
Ibuprofen and other NSAIDs are not suitable for everyone. You should check with a doctor or pharmacist before taking ibuprofen if you:
- Have a history of stomach ulcers, reflux, or gastrointestinal bleeding
- Have kidney disease or reduced kidney function
- Have heart disease, high blood pressure, or a history of stroke
- Are pregnant, particularly in the third trimester
- Take blood thinners, certain blood pressure medications, or other regular prescription medicines
- Have asthma that has previously been triggered by NSAIDs
For children, always use the paediatric formulation and dosing guidance provided on the label or by your pharmacist, since adult products and doses are not appropriate for kids.
When paracetamol is the safer first choice
Paracetamol is generally considered the go-to option for people who fall into any of the categories above, and it is typically the first choice for pain relief during pregnancy, although you should always confirm this with your doctor or obstetrician rather than assuming it applies to your situation. It is also gentler on the stomach for people with a history of reflux or ulcers.
Pain relief is not a substitute for treatment
However effective either medication is at managing discomfort, neither treats the underlying cause of tooth pain. Persistent, worsening, or severe pain, especially with swelling, fever, or pain that keeps you up at night, needs a dental assessment. Our guide on why toothache feels worse at night looks at one of the most common patterns patients describe, and our article on gum abscess versus tooth abscess explains two of the more serious causes of dental pain that need prompt attention rather than ongoing pain relief. If you are not sure whether your pain counts as an emergency, our guide on what to do when you need an emergency dentist can help you work out the next step, and if the pain started after losing a filling, our companion piece on what to do if you've lost a filling is worth a read too.
Frequently asked questions
Can I take ibuprofen and paracetamol together for a toothache?
Many dentists suggest this combination for short-term relief in healthy adults, staggering the two medications according to the dosing instructions on each product's label. Check with a pharmacist if you are unsure or take other regular medications.
Which is stronger for toothache, ibuprofen or paracetamol?
Ibuprofen is generally considered more effective on its own for dental pain because most toothache involves inflammation, which ibuprofen targets directly. Paracetamol can still help, particularly for milder pain or when ibuprofen is not suitable.
Is paracetamol safer than ibuprofen?
Both are safe when used as directed, but they carry different risks. Ibuprofen can affect the stomach, kidneys, and certain heart conditions, while paracetamol carries a risk to the liver at doses higher than recommended. Neither should be taken beyond the labelled dose.
What can I take for tooth pain if I'm pregnant?
Paracetamol is generally considered the first choice for pain relief during pregnancy, but you should always confirm this with your doctor or obstetrician rather than self-medicating, and let your dentist know you are pregnant so they can guide you appropriately.
Why does my toothache come back when the medication wears off?
Pain relief only manages the symptom temporarily. If pain returns as soon as medication wears off, that is a sign the underlying issue, such as decay, infection, or a crack, needs to be assessed and treated by a dentist.
How long is it safe to take pain relief for a toothache before seeing a dentist?
Pain relief should be seen as a short-term bridge, not an ongoing solution. If you are relying on medication for more than a day or two, or your pain is getting worse, it is time to book a dental appointment.
