Tritan After the Dentist

So Tritan had caps put on his teeth yesterday. He has enamal hypoplasia, which means the enamel on his teeth didn't form right. I had that problem as a kid, and had caps put on, too. Plus, some of his cousins on Brian's side of the family have it too, so I guess that's two counts against him.
Because the enamel didn't form right, he is more prone to cavities and decay. When he was 4, he had 2 root canals! Since then, he's had multiple fillings, and now the white amalgam fillings he has caused part of his tooth to crack and sheer away. He just woke up one morning and felt the rough edges with his tongue. As can be expected with someone with so many "bad" trips to the dentist, he hates going and it causes him a lot of anxiety. He didn't even tell me about his chipped tooth until he had an "incident" at school. We were worried that school had taken a turn for the worst again (he had a hard year adjusting last year), when he finally fessed up that he was worried about his tooth and nervous about having to have more dental work done.
Because he is so anxious we opted to give him an extra dose of "relaxing medicine" with the gas before his teeth were capped. He got pretty tired but didn't do anything crazy (did you see David After the Dentist on You-Tube?). Afterwards, he said he was glad he opted for the extra medicine, cause it made everything seem like a dream.
Actually, I was told that all the kids had problems with their enamel 3 years ago, but because they got flouride treatments regularly, and I bought the ACT flouride rinse, they don't seem to have the same problems. I don't know if it is because of that or if they are just lucky, but I wish I had started taking Tritan to the dentist when he was younger.
