Why don't I have cavities?
I drink pepsi a lot and have a lot of junk food (potato chips, candy, cookies, etc). But I also have a lot of fruits. I haven't gone to the dentist for several years. But I don't understand why I don't have any cavities. My mouth doesn't hurt at all, despite the unhealthy foods. Am I just lucky? Or does fruit prevent cavities? (I am also really athletic, so i'm not fat. (before you ask))
