I am now 5 and a half months out. There is still a bit of pain. There is always some dryness in the back of my throat that makes it a bit tight feeling. I would say for me the actual mouth pain was gone around 4 1/2 to 5 months.
At 9 weeks I was still forcing every bite down. I don't know if I will ever get back to wolfing. While my saliva has come back about 30%, it still makes a difference in how food is chewed and swallowed.
