There are no eating or drinking restrictions after sealant application (except avoiding sticky candy). Flossing and brushing are still extremely important, even after sealants are placed. Sealing teeth is only one part of the preventive strategy. While sticky and hard candies are never a good idea, they can chip or break your new sealants and should be avoided. Sealants may feel “slippery or smooth” until a few meals are eaten. This is normal!
