several tongue problems after dental visit

My problem started a couple days after my first visit with a new dentist. Before, I had not seen a dentist in over a year. He only did x-rays and teeth cleaning.
My first symptons were soreness. The edge of my tongue and underneath was very tender. It made it very difficult to eat. I finally looked under my tongue and what i saw was extremely shocking to me. I had what appeared to be little gray risen circles on one side of my tongue. Eventually both sides had the gray/white areas. The circles eventually evolved into wiggly-like lines and then the circle went away and it became more of a white coating with some areas raised looking.
I went back to the dentist and showed him my tongue. I told him it happened after I saw him and I had never had something like that before. He said it looked like some kind of bacteria or fungus and decided it was probably the toothpaste i switched to by his recomendation after i saw him last. I switched to sensodyne extra whitening with fluriode. Since then I have switched to pronamel and have not noticed a difference. I have tried salt rinses and brush underneath there everyday and it doesn't look any better.
Now, the strip that connects my tongue to the bottom of my mouth is affected. The little bumps on the bottom of the strip are swollen and there is what looks like a third bump..like its splitting. It's still very tender there, on the sides of my tongue, and has the white residue. I now even noticed an orange coating in the back of the top of my tongue that will come off if i wipe it. My tongue feels swollen which makes it hard to talk and the pain keeps me from eating a lot of foods.
Any help would be really appreciated..I have searched my symptons over and over online and haven't found anything that resembled this closely. Thank you.

My suggestion is to see an oral surgeon for a definitive diagnosis.

I am returning to my dentist within the next couple weeks but I was hoping for some kind of explanation or direction so I could make this a bit more comfortable until then and also be sure I am not doing anything that is perpetuating the condition.
