Dental sealants are preventative restorations aimed at covering up those areas of the tooth most likely to get cavities. Tooth decay typically starts in difficult to clean pits and grooves of teeth. Sealants are bonded into those pits and grooves to prevent bacteria from accumulating in them. Don't worry, this procedure is completely painless and we don't even have to numb the area.
Dr. Mitsos recommends sealants are mostly for children as their 6 and 12 year old molars come in, although, anyone with deep pits and grooves could benefit from dental sealants.
