When? How?

Around age 6, the first permanent molars - also called six year molars - erupt in the mouth, behind the last primary molars. Upon, eruption these teeth, must be evaluated for sensitivity to caries for the reasons below:

  • The enamel of a newly erupted tooth is soft and porous. It takes up to 5 years after the eruption of permanent teeth, for the enamel to harden and mature by the intake of calcium and phosphorous from the environment, so to become less soluble and more resistant to dental decay.
  • Anatomically, these teeth have multiple narrow and deep grooves and pits which easily collect debris and bacteria (picture 1).
  • Young children have difficulty in cleaning adequately these teeth, due to their anatomy and their posterior position. Actually many kids never brush these teeth.
  • So, for the 3 above reasons and after careful evaluation of the child's caries risk and previous experience to dental caries the dentist may consider placing sealants on the 6 year molars (picture 2).

Sealants: What are they? How do they benefit your teeth?

  • Sealants are white or clear fillings (picture 2) which are placed in the pits and fissures of the molar teeth in order to avoid the accumulation of food and microbial plaque into fissures.
  • Sealants are placed on healthy but sensitive to caries teeth, before they acquire caries without removing any tooth structure.
  • They have a liquid consistency when placed on the teeth in order to be able to flow into the narrow grooves. Then the Dentist uses a light curing device which transforms the sealant to a very hard mass.
  • Their life span ranges from 4 - 6 years.
  • Sealants can provide 100% protection from caries if they remain intact on the teeth.
  • Sealants need observation and maintenance. Broken or partially lost sealants could put the tooth into the risk of caries since they can trap bacteria and debris.
  • Sealants can mainly be placed on the occlusal surfaces of the teeth. Therefore, they can only prevent occlusal caries, not proximal caries.
  • However, according to research in the US 85% of dental decay occurs on the occlusal surface of the teeth, therefore the preventive benefit of them is significally high (scheme).

Conclusion: Not all children need sealants. Sealants are recommended mainly in high risk patients for developing dental decay, and particularly in those patients who are prone to develop caries on the occlusal surfaces of their teeth.
