Extra Teeth: Is It a Wisdom Tooth or Something Else? - Dentistry

An extra tooth?


Hello Doctor, I suddenly noticed a small tooth that is half the size of the second upper molar next to it.
My family thinks it might be a wisdom tooth, but this small tooth is growing right next to the molar and is very tiny.
The original molar also seems to be missing a corner, which is right next to the small tooth.
So, I apologize for asking, but could you clarify whether this situation indicates a wisdom tooth or if it’s a fragment that has broken off? Since there is currently no pain, I am wondering if I need to see a dentist.
If so, what kind of treatment might be necessary? Thank you for your response!

Hello: Based on your description, it appears to be an impacted wisdom tooth.
If there is swelling, pain, foul odor, or pus, it is recommended to seek immediate treatment.
If there are currently no abnormalities, it is advisable to monitor the situation and have the wisdom tooth extracted at a dental clinic once the situation stabilizes.
Sincerely, Lin Chia-Yung, Department of Dentistry, Taichung Hospital, Ministry of Health and Welfare.

Dear Patient,
Thank you for your detailed inquiry regarding your dental concerns. Based on your description, it sounds like you are experiencing a complex dental situation that involves multiple teeth, including wisdom teeth, and possibly other dental issues. Let’s break down your questions and provide some clarity.

1. Understanding the Extra Tooth: The small tooth you mentioned next to your upper left second molar could potentially be a supernumerary tooth (an extra tooth) or a fragment of a tooth that has broken off. Given that it is adjacent to the molar and you noted that the molar is missing a piece, it is essential to have a dental professional evaluate this. While it may not be causing pain currently, it could lead to complications if it is indeed a fragment or if it interferes with your bite or oral hygiene. A dental examination, including X-rays, would help determine the nature of this extra tooth and whether any treatment is necessary.

2. Wisdom Teeth Considerations: Wisdom teeth, or third molars, typically emerge in late adolescence or early adulthood. If the small tooth is indeed a wisdom tooth, it may not be fully erupted or could be impacted. Impacted wisdom teeth can lead to various issues, including infection, crowding of adjacent teeth, and pain. If you have concerns about your wisdom teeth, it is advisable to consult with a dentist who can assess their position and health.

3. Treatment Options: If the extra tooth is a supernumerary tooth or a fragment, treatment options may vary. If it is a fragment of a tooth, extraction may be necessary to prevent further complications. If it is a supernumerary tooth, your dentist will evaluate its position and determine if it needs to be removed or if it can remain without causing issues. Regular dental check-ups are crucial to monitor the situation, especially if you notice any changes, such as pain or swelling.

4. Preventive Care: Regardless of the current situation, maintaining good oral hygiene is essential. Ensure you are brushing and flossing regularly, especially around the area where the extra tooth is located. If you find it challenging to clean around this area, consider using an interdental brush or a water flosser to help keep it clean.

5. When to Seek Help: If you notice any changes, such as pain, swelling, or difficulty in chewing, it is crucial to seek dental care promptly. Even if you are not experiencing pain now, it is wise to have a dental professional evaluate the area to prevent potential issues down the line.

In conclusion, while the extra tooth may not be causing immediate problems, it is essential to have it evaluated by a dentist to determine its nature and any necessary treatment. Regular dental visits are key to maintaining oral health and addressing any issues before they become more serious. If you have further questions or concerns, please do not hesitate to reach out to your dental care provider.

Wishing you good health and a pain-free smile!
