Can Wisdom Teeth Grow Back After Extraction? A Dental Inquiry

The same area developing two sets of wisdom teeth?

Hello Dr.
Chang: Three years ago, I had my lower left wisdom tooth extracted.
Recently, the gums in that area have been frequently swollen and inflamed.
When I visited the dentist, I discovered that there is still a crooked tooth (very intact) inside.
The doctor didn't believe that I had previously had a tooth extraction there, but I checked my medical records at the previous clinic and confirmed that the lower left wisdom tooth was indeed extracted.
I would like to ask the doctor if, after I have this tooth extracted, it will grow back again? I really do not want to undergo another tooth extraction.

Dear user, based on your description, you had your lower left wisdom tooth extracted three years ago.
Recently, you are experiencing gum inflammation, and upon examination, it was found that there is still a wisdom tooth present.
It is recommended that you consult a dentist for X-ray examinations (panoramic X-ray and periapical X-ray) to check if there are any other wisdom teeth, impacted teeth, or other abnormalities present in the mandible, and to determine if further treatment or intervention is necessary.
The inflamed wisdom tooth may require treatment, medication, or an assessment to see if extraction is needed.
Thank you for your inquiry.

When it comes to the question of whether wisdom teeth can grow back after extraction, the straightforward answer is no; once a tooth is extracted, it does not regenerate or regrow. However, there are some nuances to consider, especially in your case where you have experienced complications after the initial extraction.

Firstly, it’s important to understand that wisdom teeth, also known as third molars, typically emerge in late adolescence or early adulthood. If a wisdom tooth is extracted, the tooth itself is removed from the jawbone, and the surrounding gum tissue heals over time. The body does not have the capability to regrow a tooth once it has been fully removed.
However, what you are experiencing—swelling and inflammation in the area where your wisdom tooth was previously extracted—could be due to several factors. One possibility is that there may be remnants of the tooth or another tooth that was not fully extracted during the initial procedure. This can lead to complications such as infection, which may cause the symptoms you are experiencing. In some cases, a tooth that was not fully removed can become impacted or cause discomfort, leading to inflammation in the surrounding gum tissue.

In your situation, it is crucial to follow up with your dentist or an oral surgeon to address the issue of the "crooked tooth" that was discovered in the area of your previous extraction. If this tooth is indeed a wisdom tooth or another molar that was not properly extracted, it may need to be removed to alleviate your symptoms and prevent further complications.

Additionally, if you are concerned about the possibility of needing further extractions in the future, it is advisable to discuss preventive measures with your dentist. Regular dental check-ups can help monitor the condition of your teeth and gums, and early intervention can prevent the need for more invasive procedures later on.

In summary, while wisdom teeth do not grow back after extraction, complications can arise from incomplete extractions or other dental issues. It is essential to consult with your dental care provider to ensure that any remaining teeth are properly assessed and treated. This will help you avoid further discomfort and the potential need for additional extractions in the future. Always communicate openly with your dentist about your concerns and symptoms, as they can provide tailored advice based on your specific dental health situation.
