Here is a practical guide to medicines for toothache, based on clinical emergency medicine sources:
Medicines for Toothache
1. NSAIDs (First Choice)
Ibuprofen is the most recommended medicine for dental pain. It works by reducing both pain and inflammation around the tooth/gum.
- Standard adult dose: 400-600 mg every 6-8 hours with food
- Works best for pain caused by swelling, pulpitis, or gum inflammation
- Naproxen sodium is another NSAID option
2. Paracetamol (Acetaminophen)
A good alternative if you cannot take NSAIDs (e.g., stomach issues, kidney problems).
- Adult dose: 500-1000 mg every 4-6 hours (max 4000 mg/day)
- Caution: Do not exceed the recommended dose - chronic overuse for toothache is a known cause of acetaminophen overdose and liver damage
Tip: Some evidence supports combining ibuprofen + paracetamol (at separate times) for stronger relief than either alone.
3. Topical/Local Anaesthetics
- Viscous Lidocaine gel - apply directly onto the affected tooth or place on a small cotton ball in the cavity. Provides temporary numbness.
- Benzocaine oral gel (e.g., Orajel) - available over the counter; apply to gum or tooth for short-term relief.
4. Clove Oil (Eugenol) - Home Remedy
- A popular and reasonably effective short-term remedy
- Saturate a piece of cotton in clove oil and place it directly in the cavity or along the gum
- Provides a few hours of relief
- Do not use more than a few times - repeated use can irritate tissue and cause nerve damage
5. Antibiotics (Only for Infection)
If there is a dental abscess or obvious infection (swelling, fever, pus), antibiotics are needed:
- Penicillin or Amoxicillin (first choice)
- Amoxicillin-clavulanate for broader coverage
- Clindamycin or Metronidazole for penicillin-allergic patients
- Erythromycin is another alternative
Antibiotics give no benefit for a simple toothache, cavity, or pulpitis without infection - they only treat infection, not pain.
6. Opioids (Last Resort / Prescription Only)
Used only for severe pain not controlled by the above options. Prescription required. Examples include codeine or tramadol. These are short-term options only and carry risks of dependence.
Other Measures
- Cold compress on the cheek - reduces swelling and numbs the area
- Saltwater rinse - helps with mild gum pain and can reduce bacteria
- Tissue adhesive (Super Glue / 2-octylcyanoacrylate) - applying to a cracked tooth can temporarily seal exposed dentin and reduce sensitivity to air/temperature (anecdotal, lasts <24 hours)
When to See a Dentist Urgently
- Pain lasting more than 2-3 days
- Swelling of the face or jaw
- Fever
- Difficulty swallowing or breathing
- Pus or bad taste in the mouth
All the above medicines are temporary measures. The underlying dental problem (decay, abscess, cracked tooth) needs proper dental treatment to resolve.

diclofenac for toothache dental pain effectiveness dose
Yes, diclofenac works well for toothache. Here is a full breakdown:
Diclofenac for Toothache
Diclofenac is an NSAID - it reduces pain by blocking prostaglandin production (COX-1 and COX-2 inhibition), cutting both pain and inflammation at the source of dental pain.
Forms Matter - Potassium vs Sodium
This is an important distinction backed by a Cochrane systematic review:
| Form | Effectiveness | Notes |
|---|---|---|
| Diclofenac potassium | Good pain relief | Faster absorption, preferred for acute pain |
| Diclofenac sodium | Limited efficacy | Slower release, not ideal for acute dental pain |
For toothache, diclofenac potassium (e.g., Cataflam, Voltfast) is the better choice over diclofenac sodium (Voltaren) because it absorbs faster.
Dosing for Toothache (Adults)
- Standard dose: 50 mg three times daily (total 150 mg/day)
- Maximum daily dose: 150 mg/day for acute pain
- Take with food or milk to protect the stomach
- Studies show good relief at 25 mg, 50 mg, and 100 mg single doses
A 2017 study comparing paracetamol, ibuprofen, and diclofenac found that diclofenac potassium 50 mg provides good relief for moderate postoperative dental pain.
How Diclofenac Compares to Other NSAIDs
- vs. Ibuprofen: Roughly similar effectiveness; ibuprofen is often preferred as a first choice because it is cheaper and has a longer safety track record
- vs. Naproxen: Diclofenac acts faster but naproxen lasts longer
- Both ibuprofen and diclofenac outperform paracetamol for dental pain with an inflammatory component
Precautions / Who Should Avoid It
- Stomach ulcers or GI problems - diclofenac (like all NSAIDs) can irritate the stomach; always take with food
- Kidney disease - use with caution or avoid
- Heart disease / high blood pressure - NSAIDs carry cardiovascular risk, especially with longer use
- Asthma - can trigger bronchospasm in aspirin-sensitive individuals
- Pregnancy - avoid in the third trimester
- Do not combine with ibuprofen or other NSAIDs - no added benefit, higher side-effect risk
- Blood thinners (warfarin, aspirin) - increases bleeding risk
Bottom Line
Diclofenac potassium 50 mg is a solid, effective choice for toothache. If it is available to you, it works as well as ibuprofen. However, see a dentist - the medicine only masks the pain; it does not fix the underlying dental problem.
