Dental sealants protect teeth against decay-causing bacteria. They are applied to teeth with deep grooves where decay most often occurs. When sealants are used for preventing decay, we find a significant reduction in the number of cavities in pediatric patients. Dr. Galligan is a strong proponent of sealants and personally applies them with the most stringent technique to ensure their highest quality. Using a special modern material, called glass ionomer, sealants at Galligan Family Dentistry not only create a cavity barrier, they also excel by being moisture tolerant and release fluoride to the tooth, creating lasting sealants and an extra level of protection. Sealants can help your children’s teeth stay 100% natural and last a lifetime, cavity-free!
