I am 34 years old. The doctors first found cancer in my gums, roof of my mouth and sinus. A year later it came back in the right side of my neck. 9 months later in my scalp. I have survived it all. My biggest problem is after the surgery to remove the roof of my mouth, and all but 4 of my teeth, my mouth only opens up about 5mm. I can not even stick my pinky finger in between my gums.I have trouble eating. I can not find a doctor to help with this problem. Does anyone know of a dentist/doctor that can help with this problem. Does anyone else have this problem. I can not get dentures because they will not fit in this tiny space.
