Sealants are a thin plastic coating that is painted on the tooth surface to fill the grooves and pits. The coating is hardened to protect the tooth surface from decay. The coating can be clear, white or slightly tinted, but is virtually impossible to see because of its placement on the back molars. Sealants are a great option for the prevention of dental caries because they act as a physical barrier to decay. The protection is determined by the sealants´ ability to adhere to the tooth.

What is the process for sealants?
Dr. Woo places a rubber dam (rain coat) on the tooth in which the sealant is to be placed. The surface of the tooth is then cleaned and rinsed to make sure that it is free of any decay. Then a special cleansing liquid is rubbed on the tooth and washed away. Finally, a seal is applied, usually on the chewing surface of the back teeth until it hardens. The procedure is pain-free and takes less than five minutes per tooth.
