Throbbing pain in the tooth

Pain of this nature indicates the development of pulpitis or apical periodontitis.

Pulpitis is an inflammation of the internal tissues of the tooth, located inside the dental canal and containing the nerve, as well as blood vessels and connective tissues. With pulpitis, the pain may not be constant, but may occur in attacks, more often at night.

Apical periodontitis is an inflammatory process that occurs in the tissues around the top of the tooth root. Accompanied by constant throbbing pain in the tooth, often radiating to the cheek or ear.

Throbbing pain, caused by the above reasons, often develops in a tooth affected by caries: untreated or under a filling (if the nerve has not been removed), but it can also occur in an apparently healthy tooth. To eliminate it, the removal of the nerve and subsequent filling of the dental canals is required.

Pulsating pain in the tooth after root canal filling

Removal of the nerve and filling of the dental canals is a surgical intervention. In this case, the damaged apex of the nerve, located inside the pulp, is removed. However, such a surgical intervention, of course, injures the tissues, therefore, after depulpation of the tooth and filling the canals, in the period from 2 to 4 days, there may be a pulling and aching pain, which gradually decreases.

If the pain has not gone away during the specified period, this indicates either that the nerve was not completely removed, or the presence of an inflammatory process that has spread beyond the top of the tooth. In this case, repeated dental intervention is required.

Pulsating pain in a tooth under a filling

Pulsating pain in a tooth without a nerve

Throbbing pain observed in a tooth with a removed nerve, under a filling or crown, occurs in case of periodontitis (cyst or granuloma of the tooth). This is an inflammation of the tissue located around the top of the tooth, with which it is fixed in the jaw bone. In this case, the pain intensifies when biting or pressing on the tooth, as the inflamed tissue is compressed. The pain can be quite strong, sharp, accompanied by swelling and often leads to the development of a flux. Periodontitis often requires extraction of the affected tooth.
