Morning
Try Capryl... It's a supplement you can get from a health food store. I have never used it for a mouth yeast infection, However, I will contend that IF you have that in the mouth, there is a problem in the gut (which is where yeast resides) .... When I sense a yeast infection coming on or have one.. I take a tablet, drink LOTS of water (as the Capryl kills off the yeast) so you want to flush it out.... anyway, take one.. drink lots of water, then if needed, I take one the next day.. or just follow instructions on the bottle.. Usually, the problem is cleared up asap.. Gotta tell you, suffered for years with candida.. and since taking Capryl, it clears it up better than ANYTHING.. and it's nice too because I don't like to take meds which can ultimately make matters worse..
Most doctors don't even know how about this stuff.. it amazes me that they don't... however, some alternative docs do.. but not too many
best of luck
