Are dental sealants necessary? - dental hygienist cover letter

My son is 8 years old and above will receive dental sealants on the teeth back in the last two years. Not covered by my dental insurance and I do not think that is 100% necessary, because they milk teeth fall yet. It seems that every time my son to the dentist to bring to push me to my son. If your child has had and how old they were when they made? How are they necessary? I've never had a child or adult, neither my husband, I do not know what to do.
