I have a decayed tooth root that hasn't been extracted, and recently I developed pulpitis. I would like to know whether an unextracted decayed tooth root can cause pulpitis.

A decayed tooth root that is not extracted may cause pulpitis. In most cases, the gums around the decayed root have largely necrotized, but this does not mean pulpitis cannot occur. If a decayed tooth root remains unextracted for a prolonged period, bacteria may invade the apex area, causing apical periodontitis and further irritating the tooth nerve, thus leading to pulpitis. Additionally, a decayed tooth root may frequently rub and irritate the oral mucosa, causing symptoms such as oral ulcers. Therefore, to avoid these adverse consequences, patients with decayed tooth roots should promptly visit the dentistry department of a qualified hospital for tooth extraction and maintain good oral hygiene habits, such as brushing teeth regularly and avoiding high-sugar foods. These measures can help prevent the occurrence of oral diseases like pulpitis.
