It was helpful. A Miracle, I don't know lol. One thing, just as important, I had my mouth sprayed everyday with a saline solution by the radiation oncology nurse, and was prescribed nystatin for a week, so probably a combination helped. The other factor, I believe, was my loss of taste, thrush, mucocitiis was more chemo induced, being radiation was more in the cervical neck, but did go up to my jawline, so they may have whacked some salivary glands too.
I found it more convienant in individual packages, no need to mix salt water, baking soda in a jug, has a neutral taste, so I used it more often too. It's free too, they pay any co-pays, or give for free without insurance, with a prescription or doctor filling filled out the form.
