Sorry to hear of Precious' problems. My kitty, Lil Bit had this also. She went thru 2 dental cleanings w/ no relief. The vet removed all her teeth, filled bone sockets, smoothed jaw and stitched up her gums. He inserted a feeding tube which she kept for approx. 6 weeks. As he explained to me - the cat is basically allergic to the plaque build up on the teeth - and w/ Lil Bit, the plaque would come back in a week. Rather than trying to just pacify the problem, the treatment he recommended was to eliminate the problem - no teeth = no plaque. (sometimes the irritation/ulceration gets so bad it can go down the esophagus) She did excellent thru the surgery, feeding tube, - she now eats dry food only. Has not had another problem since. Good luck -
