Hi, I was suffering with cavity so got my tooth extracted today but the some part of it is still remaining inside but the dentist said it won't be any problem it will heal after some time. But I'm afraid that if I It'll be of any problem because i've experienced abscess in this tooth once so afraid of still having remains of cavity. And that dentist told me that this root part is quite strongly attached to so she drilled the part that is visible for her .so please anyone tell if this will cause any problem.
