I have a broken tooth, it happened in my childhood. So my father took me to a small dentist 5 years back and he kept some kind of tooth cap and cemented that to my broken tooth. For that he even grinded my tooth which is very uncomfortable. But in the end it is over at that time. But after few days that new tooth cap is started becoming brown and I don't know why. It started looking very odd. And after few days that tooth cap completely came out and the cement was gone. From that time I'm afraid to go through that process. So I didn't went to any dentist. But now I want to correct my broken front tooth. Can you please suggest a best way?
