My four year old has poor tooth enemal at least that is  what I am being told by her dentist.  I trust her dentist though, I known her for a while she also my ten year old dentist too.  Right now my daughter teeth are okay but she get little cavities very easily.

My dentist said that I could put on dental sealants and that will help protect her teeth better and slow down her getting any cavities.  I told her I would think about it since I do not have dental insurance and have been just paying for our dental care at this point.

Can someone tell me what are dental sealants and is it really worth  paying for my daughter to have it done.   Any info would be good.
