Oral Pain: Causes and Concerns About Oral Cancer

What causes a burning or tingling sensation in the oral cavity?

Hello, I would like to ask about a relative's condition.
Recently, they have been experiencing a tingling and burning sensation in their mouth after eating spicy foods.
There are many small, unclear white spots protruding on the inner membrane of the lower front part of the mouth (not very noticeable).
Additionally, there is an irregular white lesion on the inner membrane of the left side of the mouth, approximately where the teeth come together, and they have a history of smoking and betel nut chewing.
Could this possibly be oral cancer?

The above situation may be caused by an immune system disorder leading to an inflammatory response of the oral mucosa, and the tingling, burning sensation is a presenting symptom.
It is advisable to consult a dentist for further diagnosis and treatment.

When it comes to oral pain and concerns about oral cancer, it is essential to understand the symptoms and potential causes that may be contributing to the discomfort. The symptoms you describe—tingling, burning sensations, and the presence of white spots or irregular white patches in the oral cavity—can be indicative of several conditions, some of which may warrant further investigation.

Firstly, the tingling and burning sensations in the mouth, especially after consuming spicy or hot foods, could be a sign of oral mucositis or irritation of the oral mucosa. This condition can occur due to various factors, including dietary choices, oral hygiene practices, or even underlying health issues. The presence of white spots or patches in the mouth could be related to oral thrush (a fungal infection), leukoplakia (a condition that can lead to cancer), or other benign conditions such as lichen planus or geographic tongue.

Given your history of chewing betel nut (檳榔), it is important to note that this practice is associated with an increased risk of oral lesions and potentially oral cancer. Betel nut contains arecoline, which can cause irritation and changes in the oral mucosa, leading to conditions that may resemble precancerous lesions. The irregular white patches you mentioned could be leukoplakia, which is often associated with tobacco use and can be a precursor to oral cancer.

While the symptoms you describe do not definitively indicate oral cancer, it is crucial to approach this situation with caution. Oral cancer typically presents with persistent sores, lumps, or patches that do not heal, along with other symptoms such as difficulty swallowing, changes in voice, or unexplained weight loss. However, early-stage oral cancer may not always present with obvious symptoms, making regular dental check-ups and oral examinations vital for early detection.

Given your concerns, I recommend the following steps:
1. Consult a Specialist: It is essential to see an oral surgeon or an oral pathologist who can perform a thorough examination of your oral cavity. They may recommend a biopsy of any suspicious lesions to rule out cancer or other serious conditions.

2. Maintain Oral Hygiene: Good oral hygiene practices, including regular brushing and flossing, can help reduce irritation and prevent infections. Consider using a mild mouthwash to soothe the mucosa.

3. Avoid Irritants: Reducing or eliminating the use of betel nut and other irritants (such as tobacco and alcohol) can significantly decrease the risk of developing oral lesions and potential cancer.

4. Monitor Symptoms: Keep track of any changes in your symptoms, including the size, shape, or color of the white patches, as well as any new symptoms that may arise. This information will be valuable for your healthcare provider.

5. Regular Check-ups: Schedule regular dental visits for professional cleanings and examinations. Your dentist can help monitor any changes in your oral health and provide guidance on maintaining a healthy mouth.

In conclusion, while the symptoms you are experiencing may not necessarily indicate oral cancer, they should not be ignored. Early intervention and proper evaluation by a healthcare professional are key to addressing any potential issues and ensuring your oral health remains optimal.
