  • Dental sealants are thin coatings painted on the back teeth (molars) that can prevent cavities for many years.
  • Dental sealants prevent 80% of cavities over 2 years in the back teeth, where 9 in 10 cavities occur.1
  • This effective intervention remains underused. Less than half of children and adolescents have dental sealants.2
  • Four in ten children (42%) aged 6 to 11 have dental sealants on permanent teeth.2
  • Among adolescents aged 12 to 19, 48% have dental sealants on permanent teeth.2
  • From 1999–2004 to 2011–2016, sealant use increased by about 75% among children aged 6 to 11 from low-income households, reaching 39% in 2011–2016. In comparison, sealant use was 45% among children from higher-income households in 2011–2016.2
  • School-age children (ages 6–11) without sealants have almost 3 times as many cavities in the first molars as children with sealants.3
  • Applying sealants in schools for about 7 million children from low-income families who don't have them could save up to $300 million in dental treatment costs.3
  • School sealant programs are an effective way to provide millions of children with sealants to prevent cavities.1
  • Adults aged 20 to 34 have more untreated cavities in their back teeth than any other age group. As a result, young adults may benefit from dental sealants.4
