Dental question about taxonomy:symptom:tooth-pain
Tooth pain usually reflects irritation of the pulp, dentine, gum, or tissues around the root and needs cause-specific assessment.
The short answer
Tooth pain is a symptom rather than a diagnosis, and its treatment depends on whether the source is decay, pulp inflammation, a crack, exposed dentine, gum disease, or trauma. The dentist uses the pain pattern, examination, vitality tests, bite tests, and imaging when needed to locate the cause.
How do the pulp and root tissues sense pain?
The dental pulp contains nerves and blood vessels inside the tooth, while the periodontal ligament surrounds the root and senses pressure. Cold or sweet sensitivity may involve dentine, biting pain may involve a crack or ligament, and spontaneous throbbing can indicate inflamed pulp.
What can you do until the cause is diagnosed?
Keep the area clean, chew on the opposite side, and use pain medicine only as directed on its label. Do not put heat, alcohol, or a crushed tablet on the gum, and do not use leftover antibiotics without a clinician’s assessment.
When should persistent tooth pain be assessed?
Seek dental care when pain persists, recurs, affects sleep, or changes the way you bite. Swelling, fever, pus, facial asymmetry, difficulty swallowing, or breathing difficulty requires urgent assessment.
What should you ask about saving the tooth?
Ask which tooth is responsible, whether the pulp is inflamed or infected, and whether the tooth can be restored. Ask how a filling, root canal procedure, extraction, gum treatment, or bite adjustment would address the particular cause.
Frequently asked questions
Why does a tooth hurt when I bite?
Biting pain can result from a crack, inflamed ligament around the root, a high restoration, or infection, so testing is needed to distinguish them.
Can a painful tooth heal without treatment?
Some temporary irritation settles, but pain from decay, a crack, or pulp disease can persist or progress and should be assessed.
