Sometimes when a baby tooth does not fall out or the permanent tooth does not appear, this is caused by a agenesis<\/strong>. Agenesis is the absence of one or more teeth and can occur in both primary and permanent teeth.<\/p>\n\n\n\n

In many cases, the permanent tooth has not formed and therefore does not \"push\" the milk tooth to fall out. As the years go by, all the milk teeth fall out, except this one, differentiated by the fact that they are smaller and whiter. <\/strong>On other occasions, a baby tooth may fall out without having the corresponding permanent tooth underneath.<\/p>\n\n\n\n

Agenesis has a genetic origin,<\/strong> and can occur in isolation (i.e. the child has nothing other than the missing teeth) or multiple. In the primary dentition, it occurs in 1% of children and in the permanent dentition in up to 9%.<\/p>\n\n\n\n

Curiously, the child with an agenesis of the baby tooth, has a 50% of probability <\/strong>If the parents, aunts, uncles or grandparents have agenesis, the probability will also be greater, due to the genetic cause mentioned above.<\/p>\n\n\n\n

The most commonly missing baby teeth are the lateral incisors <\/strong>and in the permanent dentition, the lower second premolars and lateral incisors, excluding wisdom teeth.<\/p>\n\n\n\n

If we see a missing primary tooth, we will take a full mouth X-ray called a orthopantomography<\/strong> when the child starts to change teeth, around the age of 6 years, to assess whether there is also an agenesis of the corresponding permanent tooth.<\/p>\n\n\n\n
