Oral cavity ulceration and tenderness?


Hello, doctor.
I often experience soreness in the grooves on both sides of my mouth, close to the back teeth, especially after eating or upon waking up, and it can last for a long time.
This occurs at least five days a week.
I initially thought it might be a temporomandibular joint (TMJ) issue, but after seeking medical attention recently, I did not see any improvement.
Every morning, I notice clear bite marks on my tongue, and the inside of my cheeks also shows signs of indentation.
However, my family has observed that I do not grind my teeth at night.
This issue has been bothering me for some time, and during severe episodes, I also experience soreness in my shoulders and neck.
I would appreciate your guidance or advice on which specialist I should consult.
Thank you.

The above situation is likely due to chronic inflammation of the tongue mucosa combined with dry mouth and insufficient saliva production, causing frequent friction of the tongue or buccal mucosa against the teeth.
The persistent soreness on both sides should raise concerns about possible gingival inflammation or recession, and even cervical tooth wear.
It is advisable to consult a dentist for further evaluation and treatment.

Understanding oral cavity discomfort can be quite complex, as it often involves multiple factors, including dental alignment, muscle tension, and even lifestyle habits. Based on your description, it seems you are experiencing discomfort in the areas near your back teeth, particularly after eating or upon waking. This discomfort, along with the presence of bite marks on your tongue and the soreness in your cheeks, suggests a few potential underlying issues.

Firstly, the discomfort in your oral cavity could be linked to your dental alignment. If you have malocclusion (misalignment of teeth), it can lead to uneven pressure on your teeth and surrounding tissues when chewing. This misalignment can also cause strain on the jaw muscles, leading to discomfort in the jaw and potentially contributing to symptoms like soreness in the neck and shoulders. It’s important to have a thorough dental examination to assess your bite and alignment. A dentist may recommend orthodontic treatment if misalignment is identified as a contributing factor.

Secondly, the presence of bite marks on your tongue and soreness in your cheeks may indicate that you are unconsciously clenching or grinding your teeth, a condition known as bruxism. While you mentioned that your family has not observed you grinding your teeth at night, it’s possible that you may be clenching during the day, especially during stressful situations. Bruxism can lead to muscle fatigue and soreness in the jaw, as well as contribute to the discomfort you are experiencing in your oral cavity. A dentist can help diagnose bruxism and may suggest a night guard to protect your teeth and alleviate muscle strain.

Additionally, the soreness you feel after eating could be exacerbated by certain foods that irritate the soft tissues in your mouth. If you notice that specific foods trigger or worsen your symptoms, it may be beneficial to avoid them. Maintaining good oral hygiene is also crucial; ensure you are brushing and flossing regularly to prevent any potential infections or irritations that could contribute to your discomfort.

Another aspect to consider is the role of stress and tension in your symptoms. Stress can lead to muscle tension in the jaw and neck, which may manifest as discomfort in the oral cavity. Incorporating stress-reducing techniques such as mindfulness, yoga, or physical therapy may help alleviate some of the tension contributing to your symptoms.

If your symptoms persist despite these considerations, it may be worthwhile to consult with a specialist, such as an oral and maxillofacial surgeon or a dentist with expertise in temporomandibular joint (TMJ) disorders. They can provide a more comprehensive evaluation and recommend specific treatments tailored to your condition.

In summary, addressing oral cavity discomfort involves a multifaceted approach that includes evaluating dental alignment, managing bruxism, maintaining good oral hygiene, and considering the impact of stress. Seeking professional dental advice is essential to identify the root cause of your discomfort and to develop an effective treatment plan.
