We recommend sealants on permanent teeth and therefore the time for sealants depends on when the child’s permanent teeth erupt.
Usually children’s first molars erupt between the age of 6 and 7. Their first and second premolars erupt between the age of 10 and 12. The second molars normally erupt between the age of 12 and 13.Keep in mind that girls usually precede boys in permanent teeth eruption. Therefore, the age estimation varies.
Permanent teeth are bigger in size and slightly darker than the baby teeth.
Decay and infection in baby teeth can cause damage to the permanent teeth developing beneath them.
