Will my dentist think I don't take care of my teeth?

Okay, first off, I am twenty years old. During my childhood, I had lousy dental care, and in middle school my dentist was a quack. He gave me a root canal and never filled it so part of my tooth broke off and it's hollow! Not only that, I have 2 visible cavities and my wisdom teeth are coming in! I'll admit that in elementary school I didn't take care of my teeth the best that I should, but once I got to middle school, I tried really well, and started brushing 2 or my times a day once I turned fourteen. I don't eat a lot of sugar, I'm vegetarian, and only drink water (I NEVER drink soda). I think I just have week anamel(?) or something. I'm going to the dentist soon, and I'm worried that he/she will scold me and accuse me of not taking care of my teeth when I do. I guess it's my fear of dentists that's getting to me, and I haven't been since I was about thirteen... Any ways to overcome this fear?

I was actually in that same situation. I was afraid to go to the dentist, I only went when I had a severe toothache. By the time I finally ended up going to the dentist I was so embarrassed. I think after awhile that's what kept me from going. I ended getting two root canals and 3 teeth removed AND braces. It really wasn't as bad as I thought it would be, the dentist actually told me "You're getting it taken care of now, so don't worry." That's the part that matters.... Good Luck!!!
