Toothache paracetamol safety
Paracetamol may reduce toothache temporarily, but it does not treat decay, infection, a crack, or gum disease causing the pain.
The short answer
Paracetamol can temporarily reduce toothache for some adults when taken exactly as directed on its label, but it does not treat the dental cause.

How does paracetamol affect toothache pain?
Paracetamol can reduce the pain signal from a toothache for a limited time when used according to the product directions. It cannot remove decay, drain an abscess, seal a crack, or treat inflamed gum tissue. The correct choice depends on age, other medicines, liver disease, alcohol use, pregnancy, and the product strength, so a pharmacist or clinician should check those factors when uncertain.
What causes toothache that paracetamol may not treat?
Toothache may come from inflamed pulp inside a tooth, decay, a crack, exposed dentine, gum inflammation, or an infection around the root. Pain that lingers after hot or cold stimuli or starts spontaneously can indicate pulp inflammation. Pain relief can mask symptoms while the underlying disease progresses, so improvement after a dose does not prove the tooth has healed.
When does toothache need prompt dental care?
Read the active ingredient and maximum daily amount on the exact package, and do not combine products that contain paracetamol. Do not place tablets against the gum. Use a soft brush, avoid very hot or cold foods, and seek a dental examination. A dentist may examine the tooth, test its nerve response, check the bite, and take an X-ray before treating the cause with a filling, root canal treatment, drainage, or extraction.
What should you check before taking paracetamol?
Arrange prompt care for toothache that lasts, returns after medicine wears off, or comes with swelling, fever, pus, a bad taste, or difficulty biting. Emergency assessment is needed for breathing or swallowing difficulty, rapidly spreading swelling, or inability to open the mouth. Children, people with liver problems, and anyone taking several medicines should obtain individual dosing advice before using paracetamol.
