Tooth decay pain killer
Pain medicine may reduce toothache temporarily, but a cavity needs dental treatment to remove decay and protect the tooth.
The short answer
Pain medicine can temporarily reduce discomfort from tooth decay, but it cannot remove the cavity or treat infection, so the tooth needs dental assessment.
How can decay progress from enamel towards the pulp?
Decay begins when acids from plaque dissolve minerals in enamel and can progress into dentine and the pulp. Pain may be brief with cold or sweet foods, or persistent when inflammation reaches the pulp.
How can you use pain relief safely for tooth decay pain?
Use an over-the-counter pain reliever only as directed on its label and check with a pharmacist if you have medical conditions, take other medicines, or are pregnant. Rinse gently with warm water, keep the area clean, avoid very hot or cold triggers, and do not place aspirin or caustic products on the gum.
When does toothache need prompt dental assessment?
Arrange prompt dental care for toothache, a visible hole, food trapping, or pain that returns when medicine wears off. Facial swelling, fever, pus, difficulty opening the mouth, or difficulty swallowing or breathing requires urgent care.
Which treatment can repair or remove a deeply decayed tooth?
Ask how deep the lesion is and whether a filling, pulp treatment, or extraction is indicated. Ask how the tooth will be isolated, restored, and protected from further decay.
Frequently asked questions
Can a painkiller cure a cavity?
No. It may reduce pain for a time, while the cavity still requires removal of decay and a suitable restoration or other treatment.
Why does a decayed tooth hurt at night?
Pulp inflammation can produce spontaneous or throbbing pain, and lying down may make the sensation more noticeable.
