I read that when one gets a root canal tooth pulled that it's best not to get a bridge (the plastic can harbor and breed harmful bacteria). What are you supposed to put in the space where the tooth was pulled? Just leave it with nothing? Some sort of seal? Wouldn't that cause other teeth to shift? I have 3 root canal teeth (all large molar teeth) and want to get them pulled....one at a time......but what can I ask my dentist to put it the empty spaces?? Anyone?
