Thanks for the information, Laura. I will definately get my daughter some Vitamin C.

As far as the sealants are concerned, I do not know what kind that were used. They were put in by our "old" dentist but they probably wouldn't tell us what kind they used even if we asked. They felt mercury was harmless (which is why we no longer go there).

One good thing is that the sealants are on her baby teeth not her permanent teeth. I believe they are on her 6-year-old molars.

Thanks!
