Ugh. Why do I have so many cavities?

Well. My first question is: Are bad teeth hereditary? My mom has really really bad teeth. As well as my brother. So are my bad teeth hereditary? When I was 12 or so I had 8 cavities when I went to the dentist. Now I'm 16 and my most recent check up said I had 16 cavities. I brush my teeth every day. At least twice. I just don't get it. It's really pissing me off. Can people have more sensitive teeth than others?

JIMMY,


CAVITIES ARE FORMED BY CERTAIN TYPES OF BACTERIA AND CAVITIES CAN ALSO BE FROM INCOMPLETE BRUSHING.
Reply:I can soooo relate. I brush 3 times a day and floss twice a day.





My dentist said it can be hereditary. For me, I have alot of acid build up in my mouth. Acid erodes the enamel on your teeth. Some people have a higher then normal acid level in thier mouth.





I never drink pop, or tea, or anything in the way of excessive sweets. Actually I'm a fitness freak, and run 7kms three times a week/eat healthy.





As long as you are brushing %26amp; flossing properly your teeth should be healthy. So if your like me then you sadly you have the genetic curse.





My dentist did give me a orange coloured protective mouth rinse though. It helps form a barrier on your enamel and prevents acid erosion. I would ask your doc about a protective rinse.





**Once acid erodes the enamel on your teeth the dentin may be exposed. Dentin is easily attacked by bacteria and you are more likely to have cavities. **So to the guy below, things are not always black and white, try reading answers and understanding them.
