Caries, or tooth decay, is a prevalent problem that occurs in wisdom teeth. If such issues are left untreated, it can lead to inflammation of the pulp also called as pulpitis.

Pulpitis causes throbbing pain in the tooth. If left untreated, it can reach the tooth pulp and cause root infection leading to apical periodontitis.
