I think it helps relieve the burning a bit as well.
And during the day, I use Biotene mouth rinse for some short term relief. For the dry mouth, I use Xylimelt tablets at bedtime, one in each cheek. I also ate kefir with fruit and honey and that worked too. But it was worth it! The burning never completely went away, but if it got better and I began to slack off on the yogurt, the burning would come roaring right back. The only thing that worked was eating yogurt which I don't really like. I tried meds for yeast for the tongue, but they didn't really help.
I had dry mouth before starting, but worse while on the meds, and I also had the change of tastes and the burning tongue. (had to substitute Ciprofloxacin for Azithromycin for the last half of treatment because of ototoxicity). I'm off 13 months of daily Big 3 since mid Feb.
