Oh great - I have yet another thing to worry about. Near the end of my time with the same dentist who is the subject of my "'Interesting' Experience w/ Former Dentist" thread, I had at least a couple of sealents (possibly more) put into my mouth. A subsequent dentist may have put in a sealant or two as well. I'm not sure if they are all still there though.
I've been having hormonal imbalance problems for years (symptoms of estrogen dominance and/or PCOS). The sealents may have contributed to the problem, but I doubt they are the main cause of my hormonal imbalance.
