The most likely reason you have a tooth growing over another tooth is a condition called hyperdontia, where extra teeth develop.
Understanding Hyperdontia
Hyperdontia refers to the presence of supernumerary teeth, meaning you have more teeth than the typical 20 (deciduous/baby teeth) or 32 (permanent/adult teeth). These extra teeth can erupt in various locations, including over existing teeth.
Possible Causes
While the exact cause of hyperdontia isn't always known, several factors can contribute to its development:
- Genetics: Certain genetic conditions are associated with hyperdontia. The provided document mentions that hyperdontia can "characterize certain genetic conditions."
- Heredity: A family history of hyperdontia can increase your risk.
- Environmental Factors: In some cases, environmental factors during tooth development may play a role.
What to Do Next
- Consult a Dentist: A dentist can properly diagnose the condition with a clinical examination and X-rays.
- Discuss Treatment Options: The typical treatment for hyperdontia is the extraction of the extra tooth. Your dentist will advise on the best course of action based on the tooth's location, its impact on surrounding teeth, and your overall oral health. The provided document confirms that "A doctor usually recommends removing the extra tooth."
- Address Potential Complications: While many complications associated with hyperdontia are minor, they should be addressed.
Example Scenario:
Imagine a situation where a small, cone-shaped extra tooth (a "mesiodens," which is a common type of supernumerary tooth) erupts on the roof of your mouth, overlapping one of your front teeth. This could cause:
- Crowding: Pushing your existing teeth out of alignment.
- Difficulty Cleaning: Making it harder to brush and floss effectively, increasing the risk of cavities and gum disease.
- Aesthetic Concerns: Affecting the appearance of your smile.
Summary
The appearance of a tooth growing over another tooth is most likely due to hyperdontia, a condition involving extra teeth. It's crucial to see a dentist for diagnosis and treatment, typically involving the removal of the extra tooth to prevent or address any complications.
