Oral Mucosal Ulcers: Symptoms, Causes, and Concerns - Dentistry

More Info

---

Oral mucosal ulcers can be a source of significant discomfort and concern, especially when they present with unusual characteristics or persist over time. Based on your description, it seems you are experiencing two distinct issues: a white, raised lesion on the right side of your oral mucosa and a series of white spots at the left corner of your mouth.

Symptoms and Characteristics
1. Right-Sided Oral Lesion: The lesion you described as white with a red border and a rough texture could be indicative of several conditions. While it is reassuring that it is not painful or itchy, the presence of a white lesion with a red halo can sometimes be associated with conditions like leukoplakia, which is a precancerous condition, or oral lichen planus, which is an inflammatory condition. However, it is essential to note that not all white lesions are cancerous. The absence of pain and discharge is a positive sign, but it is crucial to monitor any changes in size, color, or sensation.

2. Left-Sided White Spots: The series of white spots at the corner of your mouth could represent a variety of conditions, including oral thrush (a fungal infection), Fordyce spots (harmless sebaceous glands), or even a form of angular cheilitis if there is any cracking or irritation. Again, the lack of pain or itching is a good sign, but persistent lesions should be evaluated.


Possible Causes
- Irritation: You mentioned consuming spicy and fried foods, which can irritate the oral mucosa and lead to the development of ulcers or lesions.
- Infection: Viral infections (like herpes simplex) or fungal infections (like candidiasis) can also cause lesions in the mouth.

- Autoimmune Conditions: Conditions such as lichen planus or pemphigus can lead to oral lesions.

- Nutritional Deficiencies: Deficiencies in vitamins (especially B vitamins, iron, and folate) can contribute to the development of oral ulcers.

- Stress: Stress can exacerbate oral conditions, leading to the development of ulcers.


Concerns Regarding Oral Cancer
Given your previous oral cancer screening in May, it is understandable to be concerned about the possibility of cancer. While the characteristics of your lesions do not immediately suggest malignancy, it is crucial to have any persistent or changing lesions evaluated by a healthcare professional. Oral cancer can present in various forms, and early detection is key to successful treatment.


Recommendations
1. Consult a Specialist: Since you have a history of oral lesions and concerns about cancer, it is advisable to see an oral pathologist or an ear, nose, and throat (ENT) specialist. They can perform a thorough examination and may recommend a biopsy if necessary to rule out any serious conditions.


2. Monitor Symptoms: Keep track of any changes in the lesions, including size, color, or the development of pain. If you notice any new symptoms, such as difficulty swallowing, persistent pain, or changes in taste, seek medical attention promptly.

3. Avoid Irritants: In the meantime, it may be beneficial to avoid spicy, acidic, or abrasive foods that could further irritate your oral mucosa.

4. Maintain Oral Hygiene: Good oral hygiene can help prevent infections and promote healing. Use a gentle toothbrush and consider a mouth rinse that is alcohol-free to avoid further irritation.

5. Consider Nutritional Factors: If you suspect that nutritional deficiencies may be contributing to your symptoms, consider discussing this with a healthcare provider who can recommend dietary adjustments or supplements.

In conclusion, while your symptoms may not immediately suggest a serious condition, it is essential to remain vigilant and seek professional evaluation to ensure proper diagnosis and treatment. Your health and peace of mind are paramount, and addressing these concerns with a specialist will provide you with the best course of action.
