Why are some children slow to teeth?
In some cases, the eruption of the permanent teeth could be delayed due to many factors. Sometimes the process is just natural and the child is just a late bloomer, but in other cases, a problem could be present where the bone or the baby teeth could be harder than normal, and therefore the permanent tooth will have a hard time making its way to the surface, and the baby tooth could be retained to adulthood. Another instance is when the permanent tooth is out of place, and so it cannot take its normal path to the correct position, and it could either erupt in an abnormal position (called ectopic eruption) or not erupt at all and get impacted in the jaws. Most of these problems will need braces in the future.
