Oral Mucosal Changes: What Do They Mean?

Roughness of the buccal mucosa?

Hello, doctor.
Recently, I have been feeling small bumps on the inner sides of my cheeks when I touch them with my tongue, but when I turn my cheeks inside out to look, there are no abnormalities.
Additionally, there is a soft, line-like swelling located just below the corner of my lower right lip, but I don't feel much when I touch it, and there are no unusual colors or wounds.
These symptoms come and go over a few days and then resolve on their own, only to reappear after some time.
Besides the sensation I feel with my tongue, there are no other noticeable symptoms.
Lastly, I have noticed white spots on the outer side of my upper lip that have been present for several years when I tighten my lip.
What could be the cause of this? Could it be oral cancer? Thank you.

The presence of soft, linear raised lesions in the oral mucosa, without pain or any discomfort, along with a sensation of small particles, is generally indicative of inflammatory changes in the oral epithelial tissue.
This condition may be related to autoimmune dysregulation or psychological stress.
Typically, it tends to resolve or recur intermittently.
Conditions such as lichen planus may be involved, and it is advisable to consult a dentist for further evaluation and treatment.

More Info

Your concerns about oral mucosal changes are valid and warrant careful consideration. Based on your description, it seems you are experiencing a variety of symptoms, including the sensation of small bumps in the inner cheeks, a soft line-like structure at the corner of your lower lip, and white spots on the outer side of your upper lip. Let's break down these issues and explore their potential implications.

1. Sensation of Small Bumps: The feeling of small bumps in the inner cheeks could be attributed to several factors. One possibility is the presence of minor mucosal lesions or irritation, which can occur due to friction from teeth, dental appliances, or even habits like cheek biting. These bumps may not always be visible but can be felt when you run your tongue over the area. Another possibility is the presence of mucoceles, which are fluid-filled cysts that can develop in the oral cavity, often as a result of minor trauma or blockage of salivary glands.

2. Soft Line-like Structure: The soft, line-like structure you describe at the corner of your lower lip could be a normal anatomical feature, such as a fold or a line of muscle. However, if it changes in size, color, or texture, it would be prudent to have it evaluated by a dental professional. These structures can sometimes be mistaken for lesions, but if they are soft and not painful, they may not be a cause for concern.

3. White Spots on the Upper Lip: The white spots you observe when you stretch your upper lip could be a manifestation of keratosis or a benign condition such as Fordyce spots, which are small, painless, pale bumps caused by enlarged sebaceous glands. These are common and typically harmless. However, persistent white patches in the oral cavity can sometimes indicate leukoplakia, which is a condition that can be associated with irritation or, in rare cases, precancerous changes. It is essential to monitor these spots, especially if they change in appearance or do not resolve.

4. Oral Cancer Concerns: Your worry about oral cancer is understandable, especially given the presence of persistent white spots and other changes. While many of the symptoms you describe may not be indicative of malignancy, it is crucial to rule out any serious conditions. Oral cancer can present with various symptoms, including non-healing ulcers, persistent lumps, or changes in the mucosa. If you have any concerns about the possibility of oral cancer, it is advisable to consult with a healthcare professional who can perform a thorough examination and, if necessary, a biopsy to rule out any serious conditions.

5. When to Seek Help: Given that your symptoms have been intermittent and self-resolving, it may not be an immediate cause for alarm. However, if you notice any of the following, you should seek professional advice:
- Changes in the size, shape, or color of any lesions.

- Persistent pain or discomfort in the oral cavity.

- Difficulty swallowing or changes in speech.

- Any new symptoms that arise.

In summary, while your symptoms may not necessarily indicate a severe condition, it is essential to remain vigilant and consult with a dental or medical professional for a comprehensive evaluation. Regular dental check-ups are crucial for maintaining oral health and addressing any concerns early on. If you have persistent symptoms or new changes, do not hesitate to seek professional advice for peace of mind and appropriate management.
