Hi, i wonder if anyone can help me, my husband had a tumour removed in December from his lower jaw, he's now under going 30 doses of radiotherapy which of course has made his mouth dry and his gums are starting to split. I can't find any clear answers on what to treat his mouth with, the initial paperwork said Difflam is ok now I've read elsewhere it can make it worse. I'm looking for something he can put on his gums to ease the risk of it drying out overnight as during the day (when he's well enough) he can sip boiled water (he can't swallow fully as his tongue has swollen up and he's still being PEG fed). He's had an overnight chemotherapy and the next one is due on  Monday.

Any advice would be appreciated, he's struggling to cope with the soreness and if i can find something to help prevent the drying out that would be much appreciated, thnaks, Lisa.
