Exposed mandible after wisdom tooth extraction?


Hello: About a month ago, I had my lower wisdom teeth extracted.
After approximately two weeks, I noticed that my mandible was exposed and painful.
I returned to the original dental clinic, where the doctor used bone cutters to trim the excess bone and prescribed some medication for me to take at home.
Now the swelling has subsided, but the mandible is still exposed (approximately 1.5 cm long and 0.3 cm wide).
Will the exposed mandible heal on its own, or will I need further treatment? Thank you for your time in answering my question!

Hello: It is not uncommon for the alveolar bone to be exposed after the extraction of lower wisdom teeth.
There are several possible reasons for this, including thin gingiva, localized necrosis due to poor blood supply, or the protrusion of the mandible in that area.
Additionally, osteomyelitis should also be considered.
Once the bone is exposed, the gingiva will usually grow back to cover the bone, but this may take time (a few months).
In some cases, surgery may be necessary to remove excessively protruding bone.
I recommend that you: 1.
Quit smoking and drinking, especially to reduce the risk of osteomyelitis associated with exposed bone.
2.
Maintain oral hygiene.
3.
Visit a hospital to investigate the cause of the exposure and assess whether further treatment is needed.
Sincerely, Dr.
Chen Yi-Chou, Dentistry.

More Info


Exposed mandible after a wisdom tooth extraction can be a concerning situation, and it is essential to address it properly to ensure healing and prevent complications. When the mandible is exposed, it indicates that the soft tissue has not adequately healed over the bone, which can lead to pain, infection, and further complications if not treated appropriately.

Firstly, it is crucial to understand that the healing process for exposed bone can vary significantly depending on several factors, including the extent of the exposure, the patient's overall health, and their ability to heal. In your case, since the exposed area is approximately 1.5 cm long and 0.3 cm wide, it is relatively significant, and the fact that it has not healed after a month suggests that further intervention may be necessary.

The initial treatment you received, where the dentist trimmed the excess bone and prescribed medication, was a standard approach to manage the situation. However, if the bone remains exposed, additional treatment options may be required. Here are some potential approaches:
1. Surgical Intervention: If the exposed bone does not heal on its own, a surgical procedure may be necessary. This could involve covering the exposed area with soft tissue grafts or other materials to promote healing. The surgeon may also assess the area for any signs of infection or necrosis that could complicate healing.

2. Bone Grafting: In some cases, if the bone is significantly exposed and there is a risk of bone loss, a bone graft may be considered. This involves placing bone material (either from the patient or a donor) over the exposed area to encourage new bone growth and healing.

3. Antibiotic Therapy: If there is any indication of infection, your dentist may prescribe antibiotics to help manage the infection and promote healing. It is essential to follow the prescribed course of antibiotics to ensure that any potential infection is adequately treated.

4. Regular Follow-Up: Continuous monitoring of the healing process is vital. Regular follow-up appointments with your dentist or oral surgeon will allow for assessment of the healing progress and timely intervention if complications arise.

5. Oral Hygiene: Maintaining excellent oral hygiene is crucial during this healing period. Gently rinsing with warm salt water can help keep the area clean and reduce the risk of infection. However, be cautious not to disturb the healing tissue.

6. Dietary Modifications: Soft foods may be recommended to avoid irritation to the exposed area. Avoiding hard, crunchy, or spicy foods can help minimize discomfort and promote healing.

In conclusion, while exposed bone after wisdom tooth extraction can heal, it often requires careful management and possibly additional treatment. It is essential to maintain open communication with your dental care provider, follow their recommendations, and attend all follow-up appointments. If you notice any signs of infection, such as increased pain, swelling, or discharge, seek immediate medical attention. Your dentist will be able to provide the best course of action based on your specific situation and ensure that the exposed mandible heals properly.
