Good for dry mouth
Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1)
These are one of the few things that help with the pain of my Sjogren's dry mouth. They stick securely and safely. They have a mild minty taste with no menthol. They dissolve without grittiness. I highly recommend them.

Works great, not always comfy but I do recommend
Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1), Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1)
I am a senior who raised a family, had a career and held down a household. Apparently, however, I’m not competent enough to use a mint 🤷♀️🤣 The first one I tried to “install” ended up in a mess in my lap. After putting on clean pjs I decided to try again, my hubby glanced over and asked why I was trying to stick my fist in my mouth and when I started laughing the mint shot halfway across the room. I am nothing if not persistent, so decided to practice with a couple. I put one in my mouth and attempted to position it with my tongue as the instructions suggest, within 2 seconds it firmly attached to the roof of my mouth. I finally managed to get two stuck onto my gums (using my finger) and they worked perfectly! Of course when I woke up there was a small tan drool spot on my clean pillowcase. I assume it’s from the side of the mint that attaches, which is a tannish brown color. Now I use one per night, they can be really hard to use sometimes but are extremely effective. They have a slightly sweet, very pleasant taste. I use multiple dry mouth products as I have COPD & use oxygen 24/7. I am prescribed 2 inhalers and a nebulizer, all of which cause awful dry mouth - to the point of feeling like my lips are stuck to my teeth some mornings. These are the ONLY things that have made that seem like less of an issue. I sleep an average of 5 hours per night and the mint has already dissolved by then, but my mouth still feels moisturized. I don’t notice any weird taste when I drink a glass of water upon waking, just a pleasant non-taste. I do recommend, just be patient! Photo is front and back next to a Tylenol caplet

Great product
Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1)
These are so helpful for me. My dentist in Chicago recommended them about 7 years ago because I have severe dry mouth. Typically I'll use 3 to get me through the night. I'll put another in my mouth after taking a sip of water if needed. These have (I believe) prevented me from having any cavities since I started using Xylimelts. The active ingredient prevents bacteria from attacking my teeth. My dentist has been pretty impressed with the outcome. There are multiple flavors, I like the mild mint and the unflavored ones. They are a little expensive, but well worth the price. Especially with no cavities and being more comfortable at night. I love the fact that they stay where you place them too.

You need these if you have dry mouth
Flavor Name: Slightly Sweet, Size: 100 Count (Pack of 1)
I have a real problem with dty mouth due to medications I take. These last at least an hour. They stick well to you gum and they keep your mouth moist, better than any other products for dry mouth. You can even use them when you go to sleep. I use 2 at a time, 1 on each side. Sometimes I just use one. I recommend if you are bothered by dry mouth. They are sugar free.
