Dental Sealants are a thin resin coating that is applied to the grooves on the chewing surfaces of your posterior teeth to help protect them from tooth decay. Most tooth decay on patients  occur on these surfaces. Sealants protect the chewing surfaces from tooth decay by keeping germs and food particles out of these grooves on the chewing surfaces. The reason why sealants are better than waiting for tooth decay is that tooth decay damages teeth permanently. Sealants can save you time, money, and sometimes the discomfort associated with dental fillings. When applying the sealant material there is not any drilling or removing of tooth structure. The sealants can only be seen up close because they are usually white, clear, or a slight tooth shade tint. Sealants are one part of total preventive dental care.
