I have tooth pain but no cavity or swelling of gums. what could it be?

Fracture: Your tooth may be fractures, you may have gum disease, or you may be grinding. See a local dentist for an exam to find out for sure.

Occlusion: Malocclusion will cause the tooth to be traumatized in the periodontal ligament and give rise to hypersensitivity and pain. See your dentist for occlusal adjustment to direct the force to a correct location on the tooth. Malocclusion may give rise to localized gingival recession, exposing the root causing hypersensitivity. Soft toothbrush for cleaning will prevent gum recession due to brushing.

Lots of possibilitie: Tooth pain can be caused by many sources. Prior dental work may have irritated the nerve, which can sometimes take years to become painful. Also, tooth clenching or griding can have a harmful effect. Occasionally, sinus-originating pain can be associated with a toothache as well. It would also be prudent to rule out pain from the gums , nearby muscles, or an adjacent tooth. Just a few options.

Tooth pain: Can be caused by a host of problems. What produces the pain is extremely helpful in determining the cause. For example- pain on pressure (bite problem, inflamed nerve, root fracture); pain to sweets (microleakage around filling); sensitivity to cold (exposed dentin, cementum); pain to heat relieved by cold (necrotic nerve); other possibilities as well. Consult with one or more dentists 4 answer.

Evaluation: Have you seen a dentist. If so, get a second opinion. If still negative. See a TMJ-orofacial pain expert. May be atypical odontalgia.
