so i am 20 yrs old. and i admitt i have taken pretty crappy care of my teeth. although they are nice and straight, i do have a ton of cavities. I just got dental ins through my mother, but im not sure how it works. All I want it to have nice looking teeth that i can take better care of. is it possible to go from a s**t ton of cavities( i have a pretty big one, right between my two front teeth), to pretty decent looking teeth? I would hate if i messed up my teeth for good.
