Blisters on gums and roof of mouth?

Answer:
This is normally referred to as Mouth Ulcers. The causes can range from simple ginigivitis to mouth cancer (don't get scared, that's a slim chance). Other causes could be a case of the measles or chickenpox, Vitamin D deficiency, syphilis...really a number of things.
In children, there is a possibility it is Herpangina. This is not a form nor strain of herpes and is usually set on by a cold, a severe fever, or chickenpox/measles.
