Why do I keep getting so many cavities?!
Question: Why do I keep getting so many cavities?
Answers:
Do you experience a lot of heartburn/indigestion/sour stomach? Do you wake up with a sour/bitter taste in your mouth? You may be experiencing acid reflux. If you are, go see your doctor. There are medications that effectively prevent this, and could cut down on your cavity formation. Many of these medications are available over-the-counter, but you should still see your doctor, because someone as young as you doesn't often get reflux to this degree, so you might need further testing.
If that doesn't work, ask your dentist for a stronger prescription-strength fluoride treatment that you can use in place of your regular fluoride toothpaste.

The same thing happened to my sister but she had 5 cavities and later at each appointment there was so many. Once we switched dentists we found that she had only ONE cavity NOT five. And she didn't even change her routine like you did. Ever since she has had no cavities. It could be your dentist.
