My Mom Has Been Suffering With Something Rare In Her

My mom has been suffering with something rare In her mouth for 6 months now. She has been to 3 FP doctors, 2 dentist and 2 ears,nose,throat doctors. Here are her symptoms. She says she feels like there is silly puddy in her gums. They are not painful, you cant feel them. They do burn on occasion. They diagnosed her with stones, needing new dentures, bacteria and burning mouth syndrome. The problem is, she has no symptoms of the stones and the only symptom of the burning mouth is it burns on a rare occasion. When she lays down she can feel this wormy substance separating in her gums. She will have to take her hands and move her flesh back into place. IT is driving her nuts. It is not in her face just her top lip and bottom gums. She has been on antibiotics, steroids, seizure medicine (for whatever reason)
