Oral discomfort


Hello, Director Lin: I have been experiencing discomfort on the inner right side of my mouth for about 5 to 6 years.
Initially, I thought it was related to my wisdom teeth, so I had them removed approximately 3 years ago, but the discomfort persists.
I constantly feel a sensation of a foreign body, swelling, and occasional tooth sensitivity, which leads me to unconsciously touch the right cheek, the area where the teeth were removed, and the nearby teeth with my tongue.
As a result, my tongue has gradually developed slight pain and mild redness.
Even pressing or massaging the outer right cheek near the earlobe causes pain.
Although both my dentist and an ENT specialist have said that everything looks normal and advised me not to be overly sensitive, this issue has been troubling me for a long time.
Thank you!

Hello: It is recommended to perform a neck and head X-ray to confirm whether there is inflammation or foreign body infection in that area.
Additionally, it is important to rule out the presence of overly deep dental implants or unsuitable crowns/bridges.
Psychogenic factors such as teeth clenching due to stress, nocturnal bruxism, or facial tapping should also be considered.
A consultation with a neurologist may help determine if there is an issue with nerve hyperactivity (sensitivity).
Blood tests can also be conducted to check for conditions such as Sjögren's syndrome or other autoimmune diseases.

Persistent oral discomfort can be a challenging issue to navigate, especially when it has been ongoing for several years. Based on your description, it seems that you have already consulted multiple specialists, including dentists and ENT doctors, without receiving a definitive diagnosis or effective treatment. This can be frustrating and disheartening, particularly when the discomfort affects your quality of life.

From your account, the discomfort is localized to the right side of your mouth, where you experience a sensation of swelling, the feeling of an obstruction, and occasional tooth pain. You also mentioned that you had your wisdom teeth removed, which is often a common source of discomfort, but the symptoms persisted. This suggests that the underlying issue may not be solely related to the teeth themselves.

One potential explanation for your symptoms could be related to nerve sensitivity or dysfunction. Conditions such as neuropathic pain can arise from nerve irritation or damage, leading to sensations of pain or discomfort in the absence of any identifiable physical cause. This could explain why both dental and ENT examinations have not revealed any significant abnormalities. It may be worthwhile to consult a neurologist who specializes in orofacial pain to evaluate whether there is a neurological component to your symptoms.

Another possibility is that you may be experiencing a condition known as burning mouth syndrome (BMS), which is characterized by a burning sensation in the mouth, often accompanied by changes in taste or a dry mouth. This condition can be idiopathic, meaning that the exact cause is unknown, but it can be associated with factors such as hormonal changes, nutritional deficiencies (like vitamin B12 or iron), or psychological factors such as anxiety or depression. A thorough evaluation by a specialist in oral medicine or a dentist with experience in managing BMS may provide insights into your symptoms.

Additionally, you mentioned that you have a habit of touching the affected area with your tongue, which can exacerbate the discomfort and potentially lead to further irritation or inflammation. It may be beneficial to consciously avoid this habit and allow the area to heal.

In terms of management, there are several approaches you could consider. If nerve-related issues are suspected, medications such as anticonvulsants (like gabapentin) or tricyclic antidepressants may be prescribed to help manage nerve pain. If BMS is diagnosed, treatment may involve addressing any underlying nutritional deficiencies, managing stress, and using topical agents to alleviate symptoms.

For immediate relief, over-the-counter topical anesthetics or mouth rinses containing lidocaine may help numb the area temporarily. Additionally, maintaining good oral hygiene and using a gentle toothpaste can prevent further irritation.

Lastly, if you are still seeking a definitive diagnosis or treatment, consider asking for a referral to a multidisciplinary pain management clinic. These clinics often have a team of specialists who can collaboratively assess and manage complex pain conditions.

In summary, persistent oral discomfort can stem from various causes, including nerve issues or conditions like burning mouth syndrome. A thorough evaluation by a neurologist or oral medicine specialist may provide clarity. In the meantime, managing habits that exacerbate the discomfort and exploring treatment options can help improve your quality of life.
