Dental question about taxonomy:symptom:tooth-pain
Tooth pain can come from decay, pulp inflammation, a crack, exposed dentine, gum disease, or pressure around an erupting tooth.
The short answer
Tooth pain can come from decay, pulp inflammation, a crack, exposed dentine, gum disease, or pressure around an erupting tooth. The character of the pain and clinical tests help locate the source, but pain intensity alone does not identify the cause.

How do the inner tooth tissues relate to pain?
Enamel and dentine protect the pulp, which contains nerves and blood vessels inside the tooth. Heat, cold, sweets, biting, or spontaneous throbbing can reflect different changes in dentine, pulp, the root tissues, or nearby gums.
What can you do before your dental examination?
Keep brushing gently, clean around the tooth, and avoid the trigger while arranging an examination. Use only a suitable labelled pain medicine and never place aspirin or caustic substances directly on the gum.
When should recurring tooth pain receive care?
Seek prompt care for pain that persists, worsens, recurs, or affects sleep or eating. Facial swelling, fever, pus, or difficulty swallowing or breathing requires urgent attention.
What treatments might be suitable for this tooth?
Ask which tooth and tissue are responsible, what tests were positive, and whether the tooth needs a filling, protective treatment, root canal treatment, or removal. Ask what changes mean that you should return sooner.
Frequently asked questions
Does tooth pain always mean a cavity?
No. Cracks, pulp inflammation, gum disease, exposed dentine, and other problems can also cause pain.
Why does a tooth hurt when I bite?
Biting pain can occur with a crack, inflamed root tissues, a loose filling, or another problem that needs testing.
