If I use them a couple of times a day, it goes away very quickly.

i haven’t had to use this product for quite a while. Curious,, how long did the pain relief last. thanks.

Hi Stephen, I've been told to use the mouth swap, which I gargle a couple of times a day for a few days, it's very good and can make your mouth feel much better after one gargle.
Start using them as soon as I feel pain in my mouth from eating, the one I use is magic.
All I do is open the small package and disolve in hot water, stir it, then add cold water to make it a warm liquid and then gargle it for a minute or so, then spit it out, don't swallow it.
