The best, but also the most expensive
Size: 160 Count (Pack of 1)
These are the best dry mouth tabs I’ve found. They actually stick-on and last for hours. I struggle so much with dry mouth when I sleep and these have been the longest lasting. They are pretty expensive, which is why I gave them 4* instead of 5, but I haven’t found any that work better.

Huge Disappointment & Waste of $17.09
Size: 160 Count (Pack of 1)
I have been using "OraCoat XyliMelts Dry Mouth Relief Oral Adhering Discs Slightly Sweet with Xylitol" everynight for years. They work like a charm and I wake up feeling fresh and ready for the day. When I saw "Oracoat® FreshMelts® Fresh Breath Stick-on™ Melts" I was super excited. I was hoping they would be a little more minty and similiar to the XyliMelts, but saddly they are not. The Freshmelts do not have a good taste, something was just off with the flavor (chemical?). They did not help moisten my mouth like XyliMelts do. Adhering well is honestly the is only positive thing. Because the XyliMelts have been such an amazing product, I purchased the 160 count for $17.09 and I am unable to return them. I really expected more from Oracoat. I would NOT recommend this product.
