I have a crown on my tooth... I had to get a root canal when I was 17 and it wasn't nearly as bad as I thought it was gonna be. Mine just looks like a regular tooth, it's all white now and they match it to the color of your tooth. I've had 2 cavities in my life and 1 turned into the root canal.
I wanna say mine was also around $800, and probably 50-60% of insurance covered it but my dental insurance sucks.
