One of your child's baby teeth, the central incisor, has not yet fallen or has been replaced by the definitive incisor. It may be an included tooth. The explanations of Dr. Jean-Baptiste Kerbrat, maxillofacial surgeon and orthodontist.
An included tooth, what is it?
- Some definitive teeth may not come out because they remain included in the jawbone. The tooth is there, but too high and blocked to get out.
- The most common inclusion is wisdom teeth as well as upper canines, maxillary canines. This problem usually appears around 12-13 years old, when the final canines are supposed to have replaced their milk counterparts.
- In a rarer but more visible way, this phenomenon can affect the upper central incisors. As a general rule, at the age of 8, the definitive central incisors must be removed. This is not the case ? A milk incisor that has not yet fallen or has not been replaced, leaves a hole in your child's mouth? These are warning signs that should prompt you to consult an orthodontist.
- With the help of a panoramic radio, this specialist will check whether it is an inclusion or not.
What is it due?
- Heredity (there are families of canines included), certain diseases such as trisomy 21 or hypothyroidism, deficiencies in vitamins A and D (rather in African countries) can be factors of inclusion of tooth. But it is often the lack of space in the upper jaw that prevents the definitive tooth from growing.
- Another fairly common cause in children, which must be vigilant: a shock during a fall in infancy on a milk tooth. This trauma, gone unnoticed, could damage the germ of the definitive tooth which suddenly has difficulties to push.
