I just took my 6-year-old son for his dental check-up, and his dentist wants to put sealant on his four adult molars to prevent future decay. She says that all the nooks and crevices in the teeth are places where decay may happen, and the sealant would prevent cavities from forming. She says the sealant is a "resin." My son apparently has one tiny cavity "possibly forming" which may not become a real cavity if he flosses well, etc.
My son has a pretty darn healthy diet, he's a lacto-ovo vegetarian by choice, eats lots of vegetables, almost no white flour products, and almost nothing containing sugar (at least at home). But, of course, his diet is not perfect -- he occasionally goes to friends' houses and eats junky food, and I try not to be the Food Police -- I just encourage him to make good choices. We brush his teeth with flouride-free toothpaste twice a day, and floss at night.
My question is: should we do the sealant? Is there more danger from sealing the teeth with what I assume is basically plastic, or from "letting" him get some cavities (maybe).
Also, when we were at the dentist they gave him a "fluoride treatment." Should I refuse this next time? Would I be better off overall finding a holistic dentist?
