Excellent product for dry mouth
Scent Name: Berry, Size: 100 Count
If you are having trouble with dry mouth, especially while sleeping, this is definitely the product for you. I have severe dry mouth and have tried multiple things including hard candy (yes, I know not very smart) as well as different biotin products, the mouthwash, the spray and the gel, which all do work, but do not last for very long. These stay in place open the corner of your mouth, last for hours and truly work. I highly recommend it if you are having a dry mouth issue

Works great
Scent Name: Berry, Size: 100 Count
I have to use these for about 1/2 a year. I keep bronchitis and sinusitis from about Oct. to April every since I was a child. When I am suffering with these I can't breath through my nose, epically at night while sleeping and would wake up several times a night with dry mouth so bad ir was literally painful. My mom turned me on to these because she was using the with her CPAP. I sometimes have a bit of difficulty getting them to stay put but overall they are great. I have tried the OG, cinnamon, and berry. The OG have no real taste, but you wake up with a sweet taste in your mouth. I tried the cinnamon because I love cinnamon and didn't listen to the reviews stating how strong the flavor is, big regret, it's like putting two or three fireballs in your mouth, won't be making that mistake again. The berry ones are actually best in my opinion. They have a light berry flavor that isn't overpowering, isn't quite as sweet as the OG. Whichever one you choose you won't wake up in pain. I do suggest using only one at first as opposed to the two they recommend, unless you like waking up with your head on a water logged pillow. One generally gets me through the night unless my congestion is super bad, then I will sometimes have to use a 2nd one about 1/2 way through my night when I wake up for the bathroom and realize it's already completely dissolved.

Excellent lozenges for dry mouth that stick to the gum and stay in place
Size: 40 Count (Pack of 1)
I've used these for years for dry mouth both during the day and at night. The have a very pleasant mint-like flavor and last for hours. What's unique about them is that one side of the lozenge has the ability to "stick" to your gum and it actually stays there. Simply put it in your mouth, push it to the spot you prefer (I like it towards the back over molars) and it will stay there for hours slowly melting and providing dry mouth relief. It works at night when you're asleep and I've never had it move or slip out of place with the risk of choking on it. It is a hard lozenge, not soft which I imagine contributes to its long life. It's roughly 1/2" in size so it will fit smaller mouths easily. If you have dry mouth, I highly recommend this lozenges and if you buy the 3 pack, they are really good value for the money.

100% works, you do have to get used them, bit uncomfortable at first but so worth it.
Size: 40 Count (Pack of 1)
I wake up with my breath feeling fresh and my mouth not emulating the sahara desert.
It took me a while to get use to these. I had to find a spot where it was comfortable and stayed put (for me thats right above the tooth right behind (the next one back from) the canine, pushed as far up into my gum/lip area as it can go.
The size takes some getting used to also (they arent huge they just feel big once in you can still talk and go about your day as normal and no kne will notice it), however they do last all night. Once you get the hang out of they’re actually quite easy to use.
I have tried both the mint (which is mild and pleasant no burning sensation and gives the freshest feeling in the morning) and the plain ones (works but being plain your mouth doesnt feel as fresh in the morning, these are great if you hate mint or worse have a mint allergy, personally I find this very thoughtful of the company)
These 100% work. I dont even sleep with my mouth open (has been confirmed) and I would still wake up with the dryest of dry mouths, it gets so bad it’ll actually wake me sometimes. My mouth would hurt in the mornings because it would be so dry.
Went in search of anything that could help and stumbled upon these tablets. Figured why not. So glad I did because now I put one of these in every night before bed and when I wake up my mouth isn't dry, these really do help keep your mouth salivating throughout the night.
I use them during the day sometimes too. Xylitol is the only thing I've found that actually helps dry mouth. Which in turns helps your teeth stay healthy. (so win win in my book)

Works pretty well, not sure about 8 hours during the night, seems like 4-5 hrs max
Size: 80 Count
I was having issues with dry mouth during the night as I use a CPAP.
Besides checking over all the hardware and seals for my CPAP, and setting temperatures/humidity, there is only so much to control. My dry mouth was causing my cheeks and jaw to get severely dried out and would wake up with an unpleasant sticking due to the dryness.
First night, I tried 1 of these on my upper molars, and it already was working wonders, but my mouth was still dry, but 80% better than the previous night without the XyliMelts. Next time I tried 2, one on each side of my lower molars, and it worked wonders! I still woke up with a little dry mouth, but it was such an improvement I will be using these every night going forward.
Each XyliMelt is individually packaged, so you don't have to worry about freshness. They pop out of the foil easily, and you can set them into your gumline before they start to set. Once they set, they do stay put. Just follow the simple directions on the box and you won't have issues. I also really like that you can drink liquids after putting them in, if needed, as I often drink water before bed, or if I wake up in the middle of the night.
The taste is excellent, a very, very light minty taste, enough to be good, but not overpowering and you will quickly forget about it, which is probably what you would want when using at night. The thickness of the melt itself is a little big, and I'll notice it in my mouth while falling asleep, but it isn't disruptive enough to distract you or wake you up.
Overall, a super good product, although slightly expensive.I think part of that is due to a niche product, but also the packaging - which to be fair is nice, since it will keep each individual melt fresh and the breakout packs mean you can take some traveling easily without worrying about bottles etc. My only complaints in the end would be the price (I will look to buy bulk now that I know they work for me) and maybe the fact it won't last a full 7-8 hrs of sleep for me, but still highly recommended for dry mouth!
