Thanks for sharing your concern.
First of all i would say please relax.I can understand, terrible pain and many more symptoms are irritating you to large extent.
For this, i would suggest you to go one by one about your problems.
As i am dentist
, i would say you must get your teeth examined once by your dentist.it can be very well treated once diagnosed.your dental history is incompletely given here.
Teeth pains, only if there is an infection, which has reached pulp.so please get examined ,take x ray
and get that particular tooth treated,which is causing pain.
Also once you finish with your dental treatment you can visit your gastroenterologist.later on the remaining problems can be well taken care of ,by your orthopedics.
Your most welcome to forward your dental queries to us.
Hope it helps.
