Post-Accident Lip and Gum Numbness: When to Seek Medical Help? - Surgery

Right upper lip and gum numbness due to a car accident?


I had a fall on August 6th and did not experience any bleeding or bruising on my cheek.
From August 6th to August 10th, the upper right side of my lip and gums became swollen and numb, similar to the effects of anesthesia.
On August 11th, the swelling and numbness extended to my right cheek and the right side of my nose.
By August 14th, my right cheek and the right side of my nose were slowly recovering.
However, as of today, the upper right lip remains swollen and numb, and pressing on it causes sharp pain.
I have noticed slight improvement, but in the past few days, when using an electric toothbrush on my upper right teeth, 2-3 teeth have experienced intense sharp pain and numbness, making it impossible to continue brushing those teeth.
There is no feeling of looseness in the teeth.
Should I see a specific type of doctor for this issue, or can it heal naturally?

More Info


Based on your description of the symptoms following your accident on August 6, it appears that you are experiencing numbness and pain in the upper right lip, gums, and surrounding areas. This could be indicative of a few potential issues, including nerve injury, dental trauma, or soft tissue damage.

Given that you initially experienced numbness and swelling localized to the upper lip and gums, it is possible that the trauma from the accident may have affected the mental nerve, which supplies sensation to the lower lip and chin. The extension of numbness to the right cheek and nose suggests that there may be some involvement of the facial nerve or other nearby structures. The fact that you are now experiencing sharp pain when brushing your teeth in that area raises concerns about possible dental issues, such as pulpitis or other dental trauma.

Here are some recommendations regarding when to seek medical help and what type of specialist to consult:
1. Dentist: Since you are experiencing significant pain in your upper teeth, it would be prudent to see a dentist first. They can perform a thorough examination, including X-rays, to assess for any dental injuries, such as fractures or damage to the pulp of the teeth. If there is an infection or other dental issue, they can provide appropriate treatment.

2. Oral and Maxillofacial Surgeon: If your dentist suspects that there is a more serious injury involving the jaw or facial bones, they may refer you to an oral and maxillofacial surgeon. This specialist can evaluate any fractures or nerve injuries that may have occurred due to the accident.

3. Neurologist: If your symptoms persist or worsen, and especially if you notice additional neurological symptoms (such as weakness, further numbness, or changes in sensation), it may be necessary to consult a neurologist. They can assess for any nerve damage and recommend further imaging studies, such as an MRI or CT scan, if needed.

4. Emergency Room: If you experience severe pain, swelling, or any signs of infection (such as fever or pus), you should seek immediate medical attention at an emergency room. They can provide urgent care and pain management.

In terms of self-care, while waiting for your appointment, you can manage discomfort with over-the-counter pain relievers such as acetaminophen or ibuprofen, as long as you do not have any contraindications to these medications. Avoiding hard or crunchy foods may also help reduce irritation in the affected area.

It is essential to monitor your symptoms closely. If you notice any worsening of numbness, increased pain, or new symptoms, do not hesitate to seek medical attention sooner. While some nerve injuries can heal on their own, others may require intervention to prevent long-term complications.

In conclusion, given your symptoms, it is advisable to start with a visit to your dentist, who can then guide you on the next steps based on their findings. Early intervention is key to ensuring proper healing and minimizing any potential long-term effects from the accident.
