Great Mint Flavor, better mouth profile
Size: 60 Count (Pack of 1)
Unlike others, I prefer these to the Zylimelts. I like the fact that the flavor is stronger and it's a good mint flavor. it has a little bit of a zing to it but it hasn't hurt my mouth. I find that these give me a better mouth feel than either Zylimelts or the Rite Aid brand which is what I was using before. I chose Rite Aid over Zylimelts because they had a better flavor and mouthfeel and were less expensive the Zylimelts, which left a scummy film in my mouth. Zylimelts are bit larger too & they hurt my mouth from their hard edges & size. Zylimelts leave a yucky coating in my mouth but didn't moisturize anywhere near as well as either Rite Aid or these Freshmelts. These have a lower height & more rounded edges so they don't hurt as much as the others. Fresh melts are also less expensive than the other two. Mostly Zylimelts had difficulty melting because they just don't moisturize well. Even my 99 year old Mom preferred Rite Aid over Zylimelt. Sadly she passed away before I discovered these wonderful FreshMelts. Personally I would suggest if this flavor is too strong for you, see if they come in another flavor, or try the Rite Aid brand of Zylimelts, called "oral care dry mouth discs" in mint flavor also available here on Amazon. They don't have as rounded a top edge as OraCoat's 2 products but they definitely moisturize better than Zylimelts, in my opinion & I think they come in another flavor too. FreshMelts definitely have the most mit flavor, thanks to the mint oil in them, which is what irritates some people. I haven't had that issue & prefer the tingle & freshness, which makes these much better for daytime use as well & lasts longer than Pur mints or Therabreath's dry mouth lozenges (tho sensitive mouths avoid their mandarin mint, it's extremely zingy, maybe even acidic, at least even I only use if out of everything else because of how strong the zing is - which is probably why they were so much cheaper than other flavors. Ha ha. Time before I got another flavor & while tingly, wasn't bad. For Nighttime however, nothing beats the adhesive disc melts. I vote Freshmelts best for good strong flavor, best comfort/size profile & also cheapest, always a plus for me!

Handy to keep in your pocket for refreshing mouth
Size: 160 Count (Pack of 1)
Oracoat FreshMelt Stick-on are great if you have dry mouth. I use them when I go to church and they stick to the roof of my mouth and stay in place for close to 2 hrs. I have also used them at night when I wake up and can't seem to get my mouth refreshed with water.

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.
