Did you know…that sealants can last as long as 5 to 10 years pediatric dental patients? Depending on a child’s oral development and risk factors for tooth decay, sealants may be applied to the teeth as young as age 6. It is at this time that the first molars typically appear. Additional molars erupt at approximately age 12. If possible, sealants should be applied to a child’s teeth immediately after any molar has appeared to reduce the risk of early decay.
