SEALANTS
Sealants are used to fill narrow grooves in a tooth that cannot be adequately cleaned by brushing. In some cases, the tooth structure has fine grooves or pits which accumulate plaque, not because the person doesn’t brush, but because they’re too narrow to allow even one bristle into them. To avoid cavaties developing over time, the dentist will brush on a coating that seals the grooves and pits, making it possible to brush off all the plaque and keep your teeth healthy.
BONDING
Bonding involves adhering composite resin material that is matched to the color of the tooth, to the front of the tooth. This is performed to repair damage caused by decay, to alter the alignment of the tooth, close gaps between the teeth, or for other cosmetic purposes.
First the surface of the tooth is roughened in order to accept the bonding. A gel is applied so the resin will adhere to the surface of the tooth. The composite is then placed on the tooth and the bonding agent hardens with intense light. The last step is shaping and polishing to give a lustrous finish.
