Permanent Teeth

Other permanent teeth eventually erupt by replacing the primary teeth and this replacement will continue until the age of 12 to 14 years. These new teeth are more yellow than the primary teeth because of their constitution where the enamel is thinner. The enamel newly appeared in the mouth is fragile and that’s why the addition of fluoride helps greatly to solidify. In addition, they also have many deep grooves, which are best protected with a dental sealant.
