Hi there:
I will postulate that you have some level of acidosis. I would guess that your saliva if acidic. This can be verified by using some pH paper with your saliva. And how can one prevent cavities if the saliva is acidic? Maybe, brushing teeth or swishing with baking soda will help alkalize the mouth. But I would encourage you to investigate the possibility of acidosis.
For more information about acidosis and pH balance you can go to

there's many more sites that can be found, just google acid alkaline balance or acidosis pH balance.
Hope this helps and good luck.
