One way to protect children's teeth is by
having enamel sealants placed. Enamel sealants are whitish plastic
coatings for the chewing surfaces of the molars where there may be tiny
grooves and pits. The plastic coat keeps the bacterial plaque and food out
of these areas since they might cause dental decay. They are usually
placed on a child's permanent back teeth or molars as soon as the crown top
has fully erupted into the mouth. The average age for this process is
initially around 6-7 years and then later, at around 12-14 years. Some
adults may benefit from this treatment also.
