At first I thought it might be the sugar that is causing my teeth to be sensitive. Since they hurt when I chew gum or caramel, or even gummies. So I tried to change to sugar free gum and gummies to see if that helped but my teeth still hurt a little from chewing even sugar free. I go to the dentist and I do not have any cavities. In fact the dentist says my teeth are very healthy and that I do take good care of them. So what up with being sensitive to chewy things.
