Works for dry mouth
Suffer from dry mouth and these disc size tablets stick to my gums, helping keep my mouth moist through the night. Brown side sticks to your gum. Contain xylitol so s little sweet. Dentist recommended them.

PRICEY and sometimes don’t stay in place!
These have a wonderful mild flavor, no mint burn, moisten your mouth for several hours, and generally always stay put, in fact if you want it out before fully dissolved, it takes a little effort with your fingernail, because they are supposed to stick and stay in place! ALSO, I DO NOT PUT ON MY GUMLINE LIKE THE INSTRUCTIONS SAY, I STICK ON THE ROOF OF MY MOUTH FOR DISCREET CONFORT!! I really do recommend for DRY MOUTH!! I DO NOT CARE FOR THE SHARP EDGY METAL INDIVIDUAL PACKAGING AT ALL, but the bottle is very pricey!!

Absolutely work!
These are absolutely fantastic. Bygone are the days of sucking on some sugary sweet Candy. Xylo melts stick as they say they do. I have found that they don't stick to artificial teeth as well. They last for hours they're comfortable. The mint ones aren't overpowering. These are a dry mouth blessing. For sure use them at night and during the day.

Invaluable sleep/ dry mouth aid
Cannot live even one night without these Xylimelts. Taste great. Stick well to mouth. Remember: poisonous to dogs. Now we have a dog so I no longer buy the bottles of loose melts as I can spill in middle of night and lose track. Extremely nerve wracking. Using the sheets of melts which you punch out one at a time. Easier to insure dog’s safety.

They may have saved my life!
These are fantastic for people with dry mouth! They have been a lifesaver for me. I HIGHLY recommend them to everyone! I carry them in my bag as well. Thanks to the one who invented them. I feel normal again!!! Easy to pop in mouth and they last overnight too.
