A sealant is a plastic material that is usually applied to the chewing surfaces of the back teeth - premolars and molars. This plastic resin bonds into the depressions and grooves (pits and fissures) of the chewing surfaces of back teeth. The sealant acts as a barrier, protecting enamel from plaque and acids.
