Dental sealants have been in the news recently and there are questions not only being asked by reporters, but by parents concerning the health and welfare of their children. I am an active member of the American Dental Association and I trust the research that they perform on materials before those materials are sold to our practice and we use them on our patients. So, I did some research on the member site of the ADA and have a copy of the ADA journal article written for patients concerning dental sealants.
My practice has placed many sealants over the years and if they are placed properly, they will help prevent tooth decay. If moisture does contaminate the site, they will without doubt fail. Thatís why it is so important to have childrenís teeth checked regularly to insure that the sealants are still present and that they are not leaking.
I recall many years ago when some sealants were pink in color so that the dental staff and the parents could see if they were still present. That we found out is no guarantee that the sealants are not leaking. So, a routine check of the sealants at a recall appointment is important. If they are leaking, they can be repaired or replaced. If the leaking sealants go untreated, decay will develop.
So, until the ADA advises that sealant placement be discontinued, we will continue to recommend them as a means to help prevent tooth decay in children.
