In children, an impacted tooth usually occurs when a baby tooth is lost, but the surrounding teeth are blocking the path for the new tooth to come through the gum. Or, if a baby tooth doesn't fall out when it is supposed to, the permanent tooth may start to shift inside the gum and grow sideways.

Why is there a tooth growing on the roof of my mouth?

The prevalence of hypodontia is 2 to 8% of the general population (excluding third molar) and oligodontia is 0.09%. to 0.3%.

Is extra teeth a mutation?

According to one theory, mutant genes give rise to supernumerary teeth and this is supported by the finding of increased supernumeraries in patients with facial and dental anomalies such as cleft lip and palate. The development of bilateral supernumeraries also suggests that they may be controlled by a mutant gene.

How common is a third set of teeth?

15 percent to 4 percent of the population, can appear in anyone but are more often associated with people who have Gardner's syndrome (a rare genetic disorder), Down syndrome, or in those born with a cleft lip. 1 Supernumerary teeth appear twice as often in adult males as they do in adult females.
