It seems like I have something unusual growing in my mouth?


Hello, doctor...
I have a lump under my scalp, and there is also a small white circle on the right side of my scalp.
I feel very scared about it.
Can you tell me what it might be?

Our oral mucosa (including the buccal mucosa, hard palate, floor of the mouth, tongue, and upper and lower lips) maintains normal metabolism under healthy conditions.
However, when our oral mucosa (including the tongue) is subjected to abnormal disturbances, such as physical irritants like sharp edges of teeth, rough fibers from betel nut chewing, or chemical irritants (such as nicotine from cigarettes and carcinogenic components from betel nut), autoimmune diseases, or invasion by foreign pathogens (such as bacteria or fungi), the normal metabolism of oral mucosal cells can be disrupted, leading to visible changes (such as lesions, leukoplakia, or erythema).
If there are any variations in the oral mucosa as described above, it is important to seek medical attention promptly for a thorough examination.

When it comes to unusual growths in the mouth, there are several possibilities that could explain the symptoms you're experiencing. Based on your description of a small growth under your tongue and a white ring on the right side, it is important to consider a few common conditions that can manifest in the oral cavity.

1. Mucocele: One of the most common causes of a bump under the tongue is a mucocele, which is a cyst that forms when a salivary gland duct is blocked or damaged. This can happen due to trauma, such as biting the inside of your mouth. Mucoceles are typically painless and can vary in size. They often resolve on their own, but if they persist or cause discomfort, a dental professional may recommend treatment.

2. Fibroma: Another possibility is a fibroma, which is a benign tumor made up of connective tissue. These growths can occur in response to chronic irritation, such as from dental appliances or habitual biting. Fibromas are usually firm and painless, and they may require surgical removal if they become bothersome.

3. Oral Candidiasis (Thrush): The white ring you mentioned could be indicative of oral thrush, a fungal infection caused by an overgrowth of Candida yeast. This condition often presents as white patches or lesions in the mouth and can be accompanied by soreness or difficulty swallowing. It is more common in individuals with weakened immune systems, those taking certain medications, or those with diabetes.

4. Lichen Planus: This is a chronic inflammatory condition that can affect the mucous membranes in the mouth, leading to white patches or lesions. Lichen planus can be associated with discomfort and may require management by a healthcare provider.

5. Leukoplakia: This condition is characterized by white patches on the mucous membranes of the mouth that cannot be easily scraped off. It can be a response to irritation, such as from tobacco use, and while often benign, it can sometimes indicate precancerous changes, so it should be evaluated by a healthcare professional.

6. Oral Cancer: While less common, any persistent growth or lesion in the mouth that does not heal should be evaluated for the possibility of oral cancer. Early detection is crucial for successful treatment, so if you have any concerns, it is important to consult a healthcare provider.

Given your symptoms, it is advisable to schedule an appointment with a dentist or an oral specialist for a thorough examination. They can provide a definitive diagnosis based on clinical evaluation and, if necessary, further testing such as a biopsy.
In the meantime, try to avoid any irritants, such as spicy or acidic foods, and maintain good oral hygiene to prevent further irritation. If you experience pain, swelling, or any other concerning symptoms, seek medical attention promptly. Remember, while many oral growths are benign, it is always best to err on the side of caution and have any unusual changes in your mouth evaluated by a professional.
