Exposed mandible
Three weeks ago, I had my wisdom teeth and the teeth in front of them extracted.
After the stitches were removed, I noticed some bone protrusion and experienced some pain.
The dentist suggested smoothing the bone.
I am a nasopharyngeal cancer patient, so I am concerned whether this could be a metastasis to oral cancer.

Hello: Nasopharyngeal cancer patients generally undergo radiation therapy, which can lead to necrosis of the blood vessels within the bones, resulting in poorer blood supply compared to the general population.
Consequently, when extracting teeth, the wounds may heal more slowly, and there is a risk of developing what is known as "radiation-induced osteonecrosis." This condition involves bone infection combined with inadequate blood supply, leading to necrosis that does not heal.
Radiation-induced osteonecrosis can sometimes be quite severe and is generally difficult to treat.
In your case, where there is exposed bone after tooth extraction, if you have undergone radiation therapy, I strongly recommend that you visit the oral surgery department of a major hospital to assess for possible radiation-induced osteonecrosis.
Simply grinding down the bone may not be the best approach.
Regarding your concerns about metastasis, the likelihood is low, but it is still advisable to consult an experienced physician for peace of mind.
However, exposed bone is a serious issue and should be addressed.
Sincerely, Dr.
Chen Yi-Chou, Dentistry.

After undergoing wisdom tooth extraction, particularly in the context of being a nasopharyngeal cancer patient, it's understandable to have heightened concerns regarding any unusual symptoms, such as exposed bone and pain. The situation you describe, where bone is protruding after the extraction, can be concerning, especially for someone with a history of cancer. However, it is essential to approach this with a clear understanding of the healing process and the implications of your medical history.
Firstly, it's important to recognize that after wisdom tooth extraction, particularly if there was significant bone removal or if the extraction was complicated, it is not uncommon for some bone to be exposed. This can happen due to the surgical technique used, the amount of bone that was removed, or the healing process itself. The pain you are experiencing could be a result of the exposed bone irritating the surrounding tissues, which is a common postoperative issue.
In terms of your specific concern about the potential for this situation to indicate a progression to oral cancer, it is crucial to understand that the presence of exposed bone alone does not equate to cancer. Oral cancer typically presents with other symptoms, such as persistent sores that do not heal, lumps, or changes in the texture of the tissue in the mouth. The fact that you have a history of nasopharyngeal cancer does warrant careful monitoring, but it does not automatically mean that any new symptoms are indicative of cancer recurrence or metastasis.
The recommendation from your dentist to smooth the exposed bone is a standard procedure to alleviate discomfort and promote better healing. Smoothing the bone can help reduce irritation to the surrounding soft tissues, which may help alleviate pain and discomfort. It is essential to follow through with this recommendation, as it can significantly improve your healing process.
Given your medical history, it is also advisable to maintain close communication with both your dentist and your oncologist. They can work together to ensure that your oral health is managed appropriately while considering your cancer history. Regular follow-ups are crucial, as they allow for monitoring of any changes in your oral health and can help catch any potential issues early.
Additionally, if you notice any new or worsening symptoms, such as persistent pain, swelling, or changes in the appearance of the area, it is vital to seek medical attention promptly. Your healthcare providers can perform the necessary evaluations, including imaging studies if needed, to rule out any serious conditions.
In conclusion, while it is natural to be concerned about your symptoms, especially as a cancer patient, the presence of exposed bone after wisdom tooth extraction is not uncommon and does not necessarily indicate cancer. Following your dentist's advice to smooth the bone and maintaining open communication with your healthcare team will be key to ensuring a smooth recovery. Always prioritize your health by seeking professional advice whenever you have concerns, especially given your medical history.
