Good day everyone, I chipped my tooth and the filling caused sensitivity in the root, everything was fine until today when I ate food and it didn't reach this tooth. The feeling was not pleasant, of course. Now "it might sound silly, but I'm terrified to go to the dentist, suddenly it will pull out or remove the root, I've been afraid of dentists since childhood?. I would like to know if it is possible to extract teeth or remove the root on my timeline.
