A sealant is a clear or shaded plastic material that our dentist applies to the chewing surfaces of your back teeth, which is where decay most often occurs. A sealant prevents tooth decay by covering the pits and grooves of chewing surfaces and sealing out decay-causing food and germs. Please call the office of C.R. (Chip) Edwards, Jr., D.D.S. for more information about how our dental sealants in Sanford, Florida, can help you.
