Some kids have extra teeth, a condition called hyperdontia, because of factors affecting tooth development. Researchers believe the causes are multifactorial and can include genetics and environmental factors.
Understanding Hyperdontia
Hyperdontia refers to the presence of extra teeth, also known as supernumerary teeth, in addition to the normal set of teeth. These extra teeth can appear anywhere in the mouth but are most commonly found in the upper incisor region (the front teeth).
Potential Causes of Extra Teeth
While the exact cause isn't always clear, contributing factors may include:
- Genetic Predisposition: Certain genetic syndromes are associated with a higher likelihood of developing supernumerary teeth.
- Environmental Factors: According to researchers, environmental factors may contribute to hyperdontia. This suggests that external influences during tooth development can play a role.
- Overactivity of the Dental Lamina: The dental lamina is a band of epithelial cells that initiates tooth formation. Overactivity in this zone during the teeth's developmental stage can cause extra teeth to form.
What does this mean?
This means that hyperdontia, or having extra teeth, is not always due to one single reason. It can be a mix of things that happen in the body and things in the environment while the teeth are forming.
