My Teeth, Just Can't Not Laugh

So today I had a dentist appointment and was met with a serious surprise. For those that don't know I have checkups every 3 or 6 months and the dentist kinda got scared. I mean, I'm not the best brusher, especially since I don't brush a lot, so when they saw my teeth and were surprised that means something because they see them every couple of months. I have 10 cavities, and about 3 worry spots. I have all those because of my diet, not because I don't brush enough. In fact when I didn't brush a lot I barely ever got cavities, and now that I've started to brush I got cavities it doesn't make sense. Well it's because I drink a lot, and I mean a giant amount, of Vitamin Water. I don't drink soda that often, well at least used to, and barely ever have candy even on Halloween. But the reason Vitamin Water destroyed my teeth is because it's more acidic than other drinks, doing more damage to a set of teeth. So now I have to go for 3 or 4 appointments to fix my cavities resulting in costing about 1000 dollars. I also need to use a super tooth paste to strengthen my teeth, which have been highly demineralized by the water and my braces.
