In this video by Dr. Randall A. Diez, a dentist in Tampa, Fl, talks about dental sealants and the ramifications about them. There are a lot of different opinions on this and a lot of different varieties of logic on this. In children's dental work regarding baby teeth, only when Dr. Diez sees evidence of a lot of decay activity does he recommend the dental sealing procedures, but most times for baby teeth it is not needed. For permanent teeth it can be a much better idea as at about a month after the tooth has erupted from the gums than they know bacteria has not had a chance to invade a tooth in the tiny grooves and pores. In his office Dr. Randall Diez has special laser equipment for helping identify if dental sealants are needed. Care must be taken to ensure that very hard to identify decay is not sealed inside, which can continue unnoticed.
