Hi.
Does she have any symptoms of pain, burning sensation? If you are referring to the 4-5 bumps at the back of the tongue, they are completely normal. These are called circumvallate papillae and are normal taste buds.
However, if she has any symptoms like pain while swallowing or chewing, she may need to be evaluated for any other lesions in the mouth.
