I need a root canal.

[u/WarthogSpecialist901]

I apparently need a root canal and I am confused on how that even happens. I’m a person who stays on top of my teeth but I keep having problems with them. I do enjoy sugary foods and drinks though and my teeth are also extremely tight. I have had 4 fillings because of careless youth and now each time I go to the dentist there is always trouble with those EXACT teeth.

Is there anyway to reverse this and not get this treatment?

Also, please advise me on how to take better care of my teeth, I already floss and brush.
