Sealants are thin coatings placed on the chewing surfaces of teeth to seal the various pits and grooves. Sealants are proven to effectively reduce cavities by limiting the debris that can accumulate on teeth.  At Allen Dental we recommend sealants on all back permanent teeth. The best time to place these protective coatings is directly after teeth erupt so no decay process has began. Sealants do not reduce the need for good brushing and flossing, but they are a great preventive measure.
