I always wondered about this. My daughter also has chewed her meds. since we changed from liquid to pill form. She is 8 and the dentist would like to put a sealant on her deep crevices in her molars. She has the same teeth I had growing up and I was always getting cavities. We have deeeep crevices. So far, they have been pretty good. (knock on wood) Has your dentist every suspected it to be the pill? Also I wonder how much doesn’t get into their system and in their teeth crevices. As much water she drinks afterward I still don’t think it is enough to rinse those teeth.
