Pain of this nature indicates the development of pulpitis or apical periodontitis.
Pulpitis is an inflammation of the internal tissues of the tooth that are inside the dental canal and containing the nerve, as well as vessels and connective tissues. In pulpitis, pain may not be permanent, but may develop as seizures, more often at night.
Upper periodontitis is an inflammatory process that occurs in the tissues around the tip of the root of the tooth. It is accompanied by a constant throbbing pain in the tooth, often giving up on the cheek or ear.
Pulsating pain caused by the above reasons, often develops in the affected tooth decay: not treated or under the seal (if the nerve has not been removed), but it can also appear in an externally healthy tooth. To remove it, you need to remove the nerve and then seal the dental canals.
Pulsating pain in the tooth after filling the canals
Nerve removal and sealing of dental canals is a surgical intervention. This removes the damaged nerve tip, which is inside the pulp. However, such a surgical intervention, of course, traumatizes the tissue, so after the depilation of the tooth and canal filling, in the period from 2 to 4 days, there may be a drawing and aching pain, which gradually decreases.
If the pain has not passed during this period, this indicates either that the nerve was not completely removed, or the presence of an inflammatory process that spread beyond the apex of the tooth. In this case, repeated dental surgery is required.
Pulsating pain in the tooth without a nerve
Pulsating pain, observing in the tooth with the removed nerve, under the seal or crown, occurs in the case of periodontitis (cyst or granuloma of the tooth). It is an inflammation of the tissue located around the tip of the tooth, with which it is fixed in the bone tissue of the jaw. In this case, the pain increases with biting or pressing on the tooth, as the inflamed tissue is squeezed. The pain can be strong enough, sharp, accompanied by swelling and often leads to the development of flux. Periodontitis often requires removal of the affected tooth.
