I had root canals on my 2 front teeth. The tooth beside them has a small crater in the top. When getting my permanent crowns, he drilled some in the cratered tooth. Now I have a big crater on the side too. I mentioned it after and they said it's just blood. I brushed my teeth later there is definitely a hole. I want to take care off my crowns but brushing is hard with the that tooth. I used all my insurance with the crowns and can't afford a filling until January. What should I do?
