Oral issues


Hello, doctor.
Recently, while looking in the mirror, I noticed a small black spot on the inside of my right cheek.
It doesn't hurt, and the facial muscles are currently normal.
It looks somewhat like a mole.
I'm not sure what this could be and whether it is serious.
By the way, can moles develop inside the mouth?

1.
First of all, congratulations on prioritizing your oral health.
2.
Common oral mucosal lesions include red and white patches, while black lesions are rare.
If a black lesion is accompanied by swelling or ulcers that persist for 2 to 4 weeks, it requires immediate attention.
3.
You can visit the dental clinic every two to three months to monitor any changes.
4.
If you are concerned that it may develop into another condition, you can directly consult an oral surgeon for excision and biopsy.
5.
Finally, I wish you good health for both your body and oral cavity.
Thank you!

More Info


When you notice a black spot in your mouth, particularly on the inner cheek, it can understandably cause concern. However, it’s important to approach this situation with a level-headed perspective. Based on the information provided, there are several potential explanations for the appearance of a black spot in your oral cavity.

1. Melanin Deposits: One common reason for a black spot in the mouth is the presence of melanin, which is the pigment responsible for skin and hair color. Melanin can accumulate in the oral mucosa, leading to dark spots that may resemble moles or freckles. This is generally harmless and is often referred to as oral melanosis.

2. Petechiae: Another possibility is the presence of petechiae, which are small, pinpoint red or purple spots that can appear due to minor bleeding under the skin or mucous membranes. If these spots are small and not painful, they may resolve on their own without treatment.

3. Oral Lesions: Sometimes, a black spot could be indicative of a more serious condition, such as an oral lesion or ulcer. These can arise from various causes, including trauma, infections, or even precancerous changes. However, if the spot is not painful and has not changed in size or appearance, it is less likely to be a serious issue.

4. Oral Candidiasis: Fungal infections, such as oral thrush, can also lead to discoloration in the mouth. While these typically present as white patches, they can sometimes appear darker if there is a secondary infection or if the lesions are bleeding.

5. Other Conditions: There are other conditions that can cause dark spots in the mouth, including certain medications, smoking, or even dietary factors. For instance, some foods and beverages can stain the mucosa, leading to temporary discoloration.

Regarding your specific question about whether the mouth can develop moles, the answer is yes. While it is less common for moles to form in the oral cavity compared to other areas of the body, it is possible for benign pigmented lesions to occur in the mouth.

In terms of severity, if the black spot is not accompanied by pain, swelling, or other concerning symptoms, it is likely not serious. However, it is always prudent to consult with a healthcare professional, particularly a dentist or an oral specialist, for a thorough examination. They can provide a definitive diagnosis and determine if any further action is necessary.

In conclusion, while a black spot in the mouth can be alarming, many potential causes are benign. Regular dental check-ups and maintaining good oral hygiene are essential for overall oral health. If you notice any changes in the spot, such as an increase in size, color change, or discomfort, it is advisable to seek medical attention promptly. Remember, early detection and intervention are key to managing any health concerns effectively.
