Dear Doctors: We have a family health situation going on, and it’s all about teeth. Our 15-year-old son has never been what would term as an enthusiastic tooth brusher, but we all recently had a checkup and he has apparently a dozen cavities! Some of them are small, but my husband is furious as we have no insurance coverage and this comes out of the family budget. He is threatening to take his cell phone away. My daughters had a couple of cavities each, but our son beat them by 6 times. I did find candy wrappers under his bed, but of course, he has ‘no idea’ where they came from. What can we do to prevent it from reoccurring?
