Oral black spots
Hello doctor, today while brushing my teeth, I noticed a black spot on the inner side of my left cheek, approximately less than 1 centimeter in size.
It looks like a mole but does not hurt and does not feel hard.
I would like to ask what kind of condition this might be.

The above situation may be due to a rupture of submucosal microvessels, resulting in small dental blisters.
It is recommended to consult a dentist for further examination.

More Info
When you notice a black spot inside your mouth, particularly on the inner cheek, it can understandably cause concern. However, it's important to approach this situation with a clear understanding of potential causes and the appropriate steps to take.
Firstly, the appearance of a black spot in the oral cavity can be attributed to several factors. One common cause is a benign condition known as a melanotic macule, which is a flat, brown or black spot that can occur on the oral mucosa. These spots are usually harmless and result from an increase in melanin production, often due to factors like sun exposure or irritation. They are not typically associated with pain or discomfort, which aligns with your observation of the spot being painless and without a hard lump.
Another possibility is a result of trauma to the oral mucosa. If you've accidentally bitten your cheek or experienced some form of irritation, it could lead to localized bleeding under the skin, resulting in a darkened area that may resemble a bruise or a black spot. This type of spot usually resolves on its own as the tissue heals.
In some cases, oral black spots can be associated with more serious conditions, such as oral melanoma, a rare but aggressive form of cancer. However, this is less common, especially in the absence of other symptoms such as pain, changes in texture, or rapid growth of the lesion. Given that your spot is small, painless, and not hard, the likelihood of it being something serious is lower, but it is still essential to monitor it.
Additionally, certain habits, such as smoking or the use of tobacco products, can lead to changes in the oral mucosa, including the development of dark spots. If you smoke, consider discussing cessation options with your healthcare provider, as quitting can significantly improve your oral health.
Given your situation, the best course of action would be to schedule an appointment with a dentist or an oral health specialist. They can perform a thorough examination and, if necessary, conduct a biopsy to determine the nature of the spot. This is particularly important if the spot changes in size, color, or texture over time, or if you develop any additional symptoms.
In summary, while the black spot you observed may be benign, it is crucial to remain vigilant and seek professional advice to rule out any serious conditions. Regular dental check-ups are essential for maintaining oral health and catching any potential issues early. If you have any further concerns or notice changes, do not hesitate to reach out to a healthcare professional for guidance.
