Can a root canal tooth still get a cavity?
Yes, only without the nerve, you would not feel it because the nerve acts as an internal warning system. Root canal teeth are not more susceptible to decay than your other teeth, and proper brushing and flossing will help prevent decay. Your family dentist checks your teeth for decay during your six-month checkup. He/she also examines your teeth for broken or loose restorations, cracks, any signs of gum disease (periodontitis), problems with your bite, and performs a cancer screen.
