Lump in mouth (Inside of cheek)
AsadAbbas posted:
Hello sirs,

I recently noticed this lump on the inside of my right cheek. It felt sour but i thought that was because my teeth had somehow irritated that part of my mouth. Anyway i took a picture and saw this:

I don't know what that is. I've had mouth sores in my bottom lip before but i don't know what this is. It feels sour on the top side but i think that is because my tooth keeps hitting it when i talk or chew.

Dear AsadAbbas ,

The lump to which you refer is the opening of "Stenson's Duct"-- the duct of one of your parotid salivary glands. Although it is grossly normal in appearance, the whitish opaque area on its surface may represent either a traumatic injury, an ulcer, purulent exudate, or even a sialolith (salivary gland ductal stone). Unfortunately, your photo does not show this feature clearly enough to make the distinction between these possibilities.

If the area continues to feel sore or feel in any way abnormal, you should allow your dentist to assess its condition.

Hope this helps...
