It's impossible to know why you have a flap of skin in your mouth without more information. There are several possibilities, and the cause will depend on the location, appearance, and any symptoms you're experiencing.
Possible Causes:
-
Lingual Frenulum: This is a thin piece of tissue that connects the underside of your tongue to the floor of your mouth. A short lingual frenulum can sometimes cause a flap of skin to appear at the front of your tongue. This is usually harmless and doesn't require treatment.
-
Epulis: This is a non-cancerous growth that can appear on your gums, sometimes resembling a flap of skin. It's usually caused by irritation, injury, or infection.
-
Oral Thrush (Candidiasis): This is a fungal infection that can cause white patches or plaques on your tongue, cheeks, or roof of your mouth. These plaques can sometimes appear like a flap of skin.
-
Oral Lichen Planus: This is an autoimmune disorder that can cause white or gray patches on your gums, cheeks, or tongue. These patches can sometimes appear like a flap of skin.
What to Do:
If you're concerned about a flap of skin in your mouth, it's important to see a dentist or doctor. They can examine the area and determine the cause. If necessary, they can provide treatment to address the underlying issue.
