Sealants are placed in deep pits and fissures of back teeth to prevent cavities from forming in these hard to reach places. No drilling is required for these preventive fills. Instead we clean the pits and grooves out well, then place a thin layer of sealant material (resin) into the space. To harden the material we use a curing light which is blue, just like when you get a filling placed. Then we check to make sure the sealant has harden and is properly ‘sealing’ the pit or fissure we want it to protect. After this is done the pit or fissure is filled up, won’t get food debris stuck, and is easy to brush with regular toothbrushing.
