What is the best pain killer for a tooth ache?

Root Canal / Extract: Most sever toothaches are a sign that the pulp is infected or necrotic (dying and liquifying) & pressure is building up that is pressing inside on nerve, bone or the underside of the gum. Root canal therapy can often save the tooth, but a post/core & crown will be needed. Decay can give minor toothaches & dentists treat with a filling. Otc pain pills may work, but see a dentist asap/.

Advil (ibuprofen): An over the counter anti inflammatory and analgesic such as advil (ibuprofen) is the best thing for dental pain. You can also alternate between advil and tylenol (acetaminophen) every 3 or so hours to attack the dental pain two ways. However, you must see a dentist to find the source of the tooth ache as soon as possible. Long term use of pain killers is not advised.

Ibuprofen: With this said, I do recommend your seeing a dentist if the pain does not go away within a few days. There may be a problem which requires addressing to prevent a more serious problem. Ibuprofen will not kill nor treat an infection. Please see a dentist.
