I have bump inside my cheeks of my mouth, i am worry?

Where is the "bump"?: Your parotid salivary gland empties into your mouth thru a duct on the inner wall of your cheeks... The duct is located in a small protrusion. This is a normal part of your anatomy. Any other "bumps" should be examined by a professional. Call your local dentist.

Get it checked: The best way to answer your question is the have a dentist look at the bump and determine exactly what it is.
