Surgical wound after wisdom tooth extraction?


I had a wisdom tooth extraction two months ago, and after the procedure, the surgeon placed two stitches on my cheek near the extraction site.
Once the stitches came out, I noticed a horizontal hard lump on my cheek.
Initially, I thought it would heal over time, but it is still present now.
Could this be a bacterial infection? Is there a possibility that it could develop into oral cancer?

In general, after the extraction of wisdom teeth, sutures may be placed at the extraction site to aid in hemostasis, depending on the size of the wound and the difficulty of the extraction.
These sutures are typically removed one week after the procedure.
However, during the chewing process, the sutures may sometimes loosen.
If a horizontal hard lump appears on the cheek side after the extraction, it could be the buccal alveolar bone plate that has not yet been properly remodeled during the healing process.
It is advisable to monitor the extraction site for any persistent pain, discomfort, or round swelling of the gum tissue, as well as any signs of redness or inflammation.
If any of these symptoms occur, it is important to return to the dentist for an evaluation as soon as possible.

After wisdom tooth extraction, it's not uncommon to experience various post-operative symptoms, including the development of hard lumps or swelling in the area surrounding the extraction site. Based on your description, it seems that you are concerned about a hard lump that has persisted for two months after your extraction, as well as the potential for infection or even more serious conditions like oral cancer.

First, let's address the hard lump you are feeling. After a tooth extraction, particularly wisdom teeth, the body goes through a healing process that can sometimes lead to the formation of scar tissue or a fibrous lump at the site of the surgery. This lump can be a result of the healing process itself, where the body lays down collagen and other tissues to repair the area. In many cases, these lumps will gradually diminish over time as the healing progresses.

However, if the lump is hard and has not improved over the course of two months, it is essential to consider other possibilities. One concern could be an infection, especially if you are experiencing additional symptoms such as pain, swelling, redness, or discharge from the site. Infections can occur after dental procedures, and they may require treatment with antibiotics or further intervention by your dentist or oral surgeon.

Regarding your concern about the potential for oral cancer, it is important to note that while any persistent lump or sore in the mouth should be evaluated, the likelihood of a hard lump at the extraction site being cancerous is relatively low, especially if it developed shortly after a surgical procedure. Oral cancer typically presents with other symptoms, such as persistent sores, difficulty swallowing, or changes in voice, and is more common in individuals with risk factors such as tobacco use or excessive alcohol consumption.

To address your concerns effectively, I recommend the following steps:
1. Consult Your Dentist or Oral Surgeon: Schedule an appointment with the dentist or oral surgeon who performed your extraction. They can conduct a thorough examination, possibly including imaging studies like X-rays, to assess the area and determine if there is an underlying issue that needs to be addressed.

2. Monitor Symptoms: Keep track of any changes in the lump, including size, tenderness, or any new symptoms that may arise. This information will be helpful for your healthcare provider.

3. Consider a Second Opinion: If you feel uncertain about the evaluation or treatment plan provided by your initial dentist, seeking a second opinion from another dental professional can provide additional insights and peace of mind.

4. Maintain Oral Hygiene: Ensure that you are practicing good oral hygiene to prevent any potential infections. This includes gentle brushing around the extraction site and possibly using an antibacterial mouthwash as recommended by your dentist.

In conclusion, while a hard lump after wisdom tooth extraction can be concerning, it is often a part of the healing process. However, given that it has persisted for two months, it is crucial to consult with your dental care provider to rule out any complications, including infection. They will be able to provide you with the most accurate diagnosis and appropriate treatment options based on your specific situation. Remember, early intervention is key to addressing any dental concerns effectively.
