You have noticed a black spot on both sides of your tongue What is this?

Here are a few possible explanations for why you might have a black spot on both sides of your tongue:

- Tongue Fissures: These are deep cracks or grooves that can form on the surface of your tongue. They can be caused by a variety of factors, including dehydration, aging, and certain medical conditions. Tongue fissures are usually harmless and do not cause any pain or discomfort. However, they can sometimes become infected or irritated, which can lead to black discoloration.

- Hairy Tongue: This is a condition in which the papillae on the surface of your tongue become elongated and appear black or brown. Hairy tongue is usually caused by poor oral hygiene, but it can also be associated with certain medical conditions, such as diabetes and HIV/AIDS.

- Tongue Trauma: If you have recently injured your tongue, it is possible that you have developed a blood blister. Blood blisters can appear as black or purple spots and can be quite painful. They usually heal on their own within a few days.

- Melanoma: This is a type of skin cancer that can occur on your tongue. Melanoma can appear as a black or brown spot that grows and changes over time. It is important to see a doctor right away if you notice any changes in the color or shape of your tongue.

Remember, self-diagnosis can be misleading and dangerous. If you are concerned about any changes in your oral health, it is important to see a dentist or doctor for a proper diagnosis and appropriate treatment.
