That sucks. I've had two cavities when I was younger, and I don't remember any pain, except a really bad taste in my mouth. I don't know if your dentist does it, but he puts some type of film on my teeth that's supposed to prevent food from getting in the cracks. I forget what the procedure is called, or if it's widely used. But, you should definitely floss. I don't floss, but if you have shitty teeth like that, it would definitely help.
