Unexplained Oral Gum Vibrations and Lip Numbness: Seeking Answers - Otolaryngology

Share to:

Irregular gum vibrations in the oral cavity accompanied by numbness in the lower lip?


I have some dental issues and for a period of time, I was only chewing on one side of my mouth.
After undergoing some dental treatments, I started experiencing strange oral vibrations that are difficult to describe, resembling a peculiar condition of localized gum vibrations.
The vibrating area moves within the oral cavity and reacts differently at various times of the day, with the vibrating gum location not being fixed.
I have undergone CBCT and X-rays, and consulted many dentists, but no dental problems have been identified.
It doesn't seem to resemble the symptoms of trigeminal neuralgia either, as several neurosurgeons I consulted also believe it is unlikely to be related to that.
Additionally, I am experiencing a very severe dry mouth issue.
It somewhat resembles the description in the link below.
I would like to ask the doctor for their thoughts.
Thank you.

Dr. Zheng Jueyi reply Otolaryngology


Hello, if there are no obvious structural issues found during the dental examination, the vibration in the gums along with the numbness in the lower lip may still be more suspiciously related to neurological factors.
However, since you have already consulted with both a neurologist and a neurosurgeon, the cause remains undetermined.
For the dry mouth issue, you may consider seeing a rheumatologist in internal medicine to evaluate for conditions such as Sjögren's syndrome.
As for the vibrations, you can consult a neurologist to see if a referral to a medical center for further evaluation is necessary.
Wishing you safety and good health.
Sincerely, Dr.
Cheng Jue-Yi, Director of the ENT Department, Taoyuan Hospital, Ministry of Health and Welfare.

The symptoms you are experiencing, including unexplained oral gum vibrations and lip numbness, can be quite perplexing and distressing. Given your history of dental issues and the treatments you've undergone, it is essential to consider several potential underlying causes for these sensations.

Firstly, the phenomenon of oral gum vibrations could be related to a few different factors. One possibility is that it could be a form of neuromuscular dysfunction. This can occur when the nerves that supply the gums and surrounding tissues become irritated or compressed, leading to abnormal sensations. Although you mentioned that consultations with neurologists did not indicate a clear neurological issue, it is still worth considering that subtle nerve irritations or entrapments could be contributing to your symptoms.

Another potential cause could be related to the dental treatments you have received. If you have undergone procedures such as fillings, crowns, or extractions, it is possible that the surrounding tissues have not healed properly, leading to sensations that might feel like vibrations. Additionally, if you have been favoring one side of your mouth for chewing, this could lead to muscle imbalances or tension in the jaw and surrounding areas, which might manifest as unusual sensations in the gums.

Dry mouth, or xerostomia, is another significant factor to consider. Saliva plays a crucial role in oral health, and a lack of it can lead to various symptoms, including discomfort, difficulty swallowing, and changes in sensation. Dry mouth can be caused by several factors, including medications, dehydration, or underlying health conditions. It is essential to address this issue, as chronic dry mouth can lead to further complications, such as increased risk of cavities and gum disease.

Given that you have undergone imaging studies like CBCT and X-rays without any findings, it may be beneficial to explore other diagnostic avenues. A thorough evaluation by an oral medicine specialist or a dentist with expertise in temporomandibular joint (TMJ) disorders could provide additional insights. They may assess for any signs of TMJ dysfunction, which can lead to referred sensations in the gums and lips.

In terms of management, it is crucial to maintain good oral hygiene and stay hydrated to alleviate dry mouth symptoms. Using saliva substitutes or mouth rinses designed for dry mouth can also be beneficial. If muscle tension is suspected, physical therapy or exercises to relax the jaw muscles may help reduce discomfort.

Lastly, if the vibrations persist or worsen, consider seeking a multidisciplinary approach, involving both dental and medical professionals, to ensure a comprehensive evaluation of your symptoms. Keeping a symptom diary, noting when the vibrations occur and any associated activities or stressors, can also provide valuable information for your healthcare providers.

In conclusion, while the exact cause of your oral gum vibrations and lip numbness remains unclear, several potential factors could be at play. A thorough evaluation by specialists in both dentistry and neurology, along with appropriate management of dry mouth, may help you find relief and improve your overall oral health.
