Do I have to get a crown after a root canal?

Answered January 30, 2012 12:20. AT VERY LEAST NEED TO PLACE A POST/ AND CORE SO IS MORE SOLID. DEPENDING ON HOW MUCH DECAY THERE WAS, CROWN IS MEANT TO KEEP TOOTH TOGETHER-KEEP FROM FRACTURING. TRY NOT TO CHEW ON IT AS ANY HARD FOREIGN OBJECTS IN FOOD-BONE CHIPS, PITS,,,,ETC. CAN CAUSE TOOTH TO FRACTURE.
