Ever had a child tell you that they seem to have an extra tooth growing out of their upper jaw behind their permanent teeth. This is probably a situation where your child has an extra tooth, or a supernumerary tooth as our family dentist in Dubai likes to call it.
If you think that this only happens to you or your child, you’re not alone as it is estimated that supernumerary, or extra teeth occur in 2% of all children, with an even higher frequency in those of Asian descent.
Supernumerary Mesiodens Tooth
Extra teeth are often called mesiodens and it may sound alien to some. What this means is that there are teeth that grow right between the two upper middle front teeth. Only about 25% of these teeth actually erupt into the mouth. Most mesiodens teeth stay in the jawbone and never make it into the mouth. Which is a complete relief for some but a nightmare for others!
What is the cause behind Supernumerary Teeth?
It is assumed that supernumerary teeth occur due to the continued growth of the tissue that forms the teeth, known as the dental lamina.
Supernumerary teeth can be hereditary or they may be associated with one of two conditions such as Gardner’s Syndrome and Cleidocranial Dysplasia.

Most supernumerary teeth form in children before the age of 20 years, although they are more commonly found with the permanent teeth rather than with baby teeth, explains the dentist at the pediatric dentistry in Dubai.

If the extra tooth is located behind the wisdom teeth, it is known as distodens.
