Rotten teeth that are not extracted for a long period of time generally do not cause cancer, but rotten teeth may cause trauma to neighboring tissues, repeated inflammation of periodontal tissues, and long-term stimulation may lead to cancerous changes in soft tissues.
Rotten teeth (clinically known as stumpy crowns and stumpy roots) are mainly caused by dental caries, dental trauma and other hard tissue defects that are not treated in time, and their main symptoms include large defects in hard tissues of the teeth, pain, and loosening and other symptoms.
Crown and root remnants generally do not cause cancer, but due to their sharp edges, they can cause trauma and inflammation of the surrounding soft tissues, and prolonged chronic stimulation may cause cancer in soft tissues such as tongue or buccal mucosa. Therefore, it is recommended to consult a doctor for symptomatic treatment in time to avoid delay or even aggravation of the condition when stumpy root or stumpy crown is found.
