Post-Wisdom Tooth Extraction: Sensitivity and Exposed Bone Concerns

Exposed upper jawbone after wisdom tooth extraction?

Hello, doctor.
Two weeks ago, I had my wisdom teeth (both upper and lower on the right side) extracted and the stitches removed.
However, I've noticed sensitivity in the two molars in front of the extracted wisdom teeth when I bite down.
What could this symptom be? Additionally, there is a protrusion of bone in the upper gum, and my dentist mentioned that it needs to be monitored.
Will this heal and the gum tissue grow back on its own? Thank you!

Dear Anonymous,
Hello! After the extraction of wisdom teeth, exposure of the maxillary bone usually heals gradually, but it still requires monitoring.
Additionally, if you experience sensitivity when biting down on the two anterior molars, please be aware that it could be a sign of periodontal disease or cavities.
It is important to communicate with your dentist about these concerns.

Thank you! Wishing you well!
Sincerely,
Dr.

More Info

After wisdom tooth extraction, it is not uncommon to experience sensitivity in adjacent teeth, as well as concerns regarding exposed bone in the gum area. Let's break down these issues to provide a clearer understanding.

Sensitivity in Adjacent Teeth
The sensitivity you are experiencing in the molars adjacent to the extracted wisdom teeth can arise from several factors:
1. Trauma to Surrounding Teeth: During the extraction process, the surrounding teeth may have been subjected to pressure or minor trauma, leading to temporary sensitivity. This is particularly common if the extraction was complicated or if the teeth were closely positioned.

2. Changes in Bite Alignment: After the removal of wisdom teeth, the alignment of your bite may change slightly. This can lead to uneven pressure on the adjacent teeth when you bite down, resulting in sensitivity.
3. Nerve Irritation: The extraction process can sometimes irritate the nerves in the area, leading to heightened sensitivity in nearby teeth.
4. Infection or Inflammation: If there is any infection or inflammation in the extraction site, it can also cause discomfort and sensitivity in the surrounding teeth.

Exposed Bone Concerns
Regarding the exposed bone in your upper jaw, this is often referred to as "exposed alveolar bone." It can occur after tooth extractions, especially if the gum tissue does not heal properly or if there was significant bone loss prior to the extraction. Here are some key points to consider:
1. Healing Process: In many cases, exposed bone can heal over time as the gum tissue regenerates. The body will gradually cover the exposed area with new gum tissue. However, this process can take several weeks to months, and it is essential to maintain good oral hygiene to prevent infection.

2. Observation and Follow-Up: Your dentist's recommendation to observe the area is prudent. They will likely want to monitor the healing process to ensure that the bone is not becoming infected and that the gum tissue is regenerating properly.

3. Signs of Complications: If you notice increased pain, swelling, or discharge from the area, it is crucial to return to your dentist for further evaluation. These could be signs of infection or other complications that may require intervention.

4. Potential Treatments: In some cases, if the bone remains exposed for an extended period or if there are complications, your dentist may recommend additional treatments. This could include procedures to promote gum healing or even surgical intervention to cover the exposed bone.

Conclusion
In summary, the sensitivity in your adjacent molars is likely a temporary issue related to the extraction process, and it should improve as healing progresses. The exposed bone in your upper jaw may also heal naturally, but it is essential to keep an eye on it and maintain communication with your dentist. If symptoms worsen or do not improve, seeking further evaluation is advisable. Always follow your dentist's recommendations for follow-up visits to ensure proper healing and address any concerns that may arise.
