The appearance of teeth growing on top of other teeth is most likely due to a condition called hyperdontia, where extra teeth develop in your mouth.
What is Hyperdontia?
Hyperdontia refers to having more teeth than the normal number (20 deciduous/baby teeth or 32 permanent teeth). These extra teeth are also called supernumerary teeth. It can occur in both baby teeth and permanent teeth, although it's more common in permanent teeth. Prevalence ranges from 0.1% to 3.8% in permanent teeth.
Possible Reasons for Extra Teeth Growing on Top
Here are some potential reasons for supernumerary teeth developing and appearing as if they are growing on top of existing teeth:
-
Genetics: Hyperdontia can be hereditary. If other family members have experienced extra teeth, there's a higher chance you will too.
-
Syndromes: Certain genetic syndromes are associated with hyperdontia. Examples include:
- Gardner syndrome
- Cleft lip and palate
- Ehlers-Danlos syndrome
-
Developmental Abnormalities: Sometimes, extra teeth simply arise due to developmental irregularities during tooth formation.
What to Do if You Have Extra Teeth
If you suspect you have extra teeth, it's important to:
-
Consult a Dentist: A dentist can diagnose hyperdontia with a clinical examination and X-rays.
-
Discuss Treatment Options: Treatment depends on the location, number, and impact of the extra teeth. Options include:
- Extraction: The most common treatment is to remove the extra teeth, especially if they are causing problems like crowding, impaction, or difficulty chewing.
- Observation: If the extra teeth aren't causing any issues, your dentist may recommend monitoring them. However, regular check-ups are necessary to assess their impact on surrounding teeth and oral health.
- Orthodontic Treatment: Braces or other orthodontic appliances may be necessary to correct any misalignment caused by the extra teeth.
Possible Complications of Hyperdontia
Leaving extra teeth untreated can lead to various complications, including:
- Crowding and Misalignment: Extra teeth can push existing teeth out of alignment.
- Impaction: Extra teeth can prevent other teeth from erupting properly.
- Root Resorption: The roots of adjacent teeth can be damaged by the extra teeth.
- Cyst Formation: Cysts can develop around impacted supernumerary teeth.
It is important to seek professional dental advice for proper diagnosis and treatment planning if you suspect you have extra teeth. Early intervention can prevent potential complications and maintain good oral health.
