how do i know if i need a root canal

To know if a root canal is needed, watch for these common signs: severe, persistent toothache especially when chewing; prolonged sensitivity to hot and cold; discoloration of a tooth turning grayish-black; pimple-like sores (abscesses) on the gums; and swollen, tender gums. These symptoms often indicate infection or damage deep in the tooth pulp that may require root canal treatment to save the tooth and relieve pain. If these signs appear, it is important to visit a dentist promptly for diagnosis and treatment.
