Is My Jaw Dislocated After Wisdom Tooth Extraction? - Dentistry

Is this considered a jaw dislocation?


I had my lower right wisdom tooth extracted during college, and the resident dentist aggressively used a hammer to break the tooth.
Ever since then, when I open and close my mouth, there is a popping sound on the right side of my cheek, accompanied by a vibration sensation.
Although it doesn't hurt, there have been one or two instances where I almost couldn't close my mouth after yawning and had to push it with my hand.
Recently, I've noticed that the sound seems to have gotten louder, and I'm worried it might worsen.
Can this be treated? Do I need surgery? Should I see a dentist? Thank you for taking the time to answer!

Hello, Miss: Thank you for your inquiry.
I would like to address your question and provide the following advice: During the tooth extraction process, if the mouth is held open for an extended period or if there is difficulty in extracting impacted wisdom teeth, the wound may be larger, increasing the risk of infection.
This could subsequently affect the temporomandibular joint (TMJ), potentially leading to temporary or permanent dysfunction.
It is advisable to consult a dentist or oral surgeon for further evaluation and treatment.
Lastly, I wish you safety and happiness!

More Info


After wisdom tooth extraction, it's not uncommon to experience various symptoms, including sounds or sensations in the jaw. Based on your description, it seems you may be experiencing some form of temporomandibular joint (TMJ) dysfunction, which can occur after dental procedures, especially if there was significant force used during the extraction.

When a wisdom tooth is extracted, particularly if it is impacted or requires extensive manipulation, the surrounding structures, including the jaw joint, can be affected. The "pop" or "click" sound you hear when opening or closing your mouth may indicate that the joint is not moving smoothly, which can be due to a misalignment or inflammation of the joint. The sensation of vibration you mentioned could also be related to the same issue.

While you are not experiencing pain, which is a positive sign, the fact that you have difficulty fully closing your mouth after yawning and that the sounds have increased could suggest that the situation is not resolving on its own. TMJ disorders can sometimes improve with conservative treatment, but if symptoms persist or worsen, further evaluation may be necessary.

Here are some steps you can take:
1. Consult a Dentist or Oral Surgeon: It's essential to follow up with a dental professional who can assess your jaw and determine if there is any structural issue or if the joint is indeed dislocated. They may take X-rays or perform a physical examination to evaluate the joint's function.

2. Conservative Treatment Options: If it is determined that you have TMJ dysfunction, your dentist may recommend conservative treatments such as:
- Heat or Ice Therapy: Applying heat or ice packs to the affected area can help reduce inflammation and alleviate discomfort.

- Jaw Exercises: Gentle stretching and strengthening exercises for the jaw can improve mobility and reduce symptoms.

- Pain Relief Medications: Over-the-counter anti-inflammatory medications can help manage any discomfort you may experience.

3. Avoid Strain on the Jaw: Try to avoid activities that may strain your jaw, such as chewing hard foods or excessive yawning. If you notice that certain movements exacerbate the symptoms, it’s best to minimize those actions.

4. Mouth Guard: If you grind your teeth or clench your jaw, a custom mouth guard may be recommended to protect your teeth and alleviate pressure on the TMJ.

5. Surgical Options: In rare cases, if conservative treatments do not provide relief and there is a significant structural issue, surgical intervention may be considered. However, this is typically a last resort after other options have been exhausted.

In summary, while it is unlikely that your jaw is dislocated in the traditional sense, you may be experiencing TMJ dysfunction as a result of the extraction. It is advisable to consult with a dentist or oral surgeon who can provide a thorough evaluation and recommend appropriate treatment options. Early intervention can often lead to better outcomes, so don’t hesitate to seek professional advice.
