DenTek Canker Relief Canker Sore Patch Relieves Canker Pain, 6 Count (Pack of 1)

It works great and makes it feel like the sore isnt even there, but it doesn’t stay on well at all, especially for someone who salivates a lot it comes off after maximum of an hour or two, I wish it had more adhesive, as far as it saying to eat in moderation I don’t suggest it at all, they fell off almost immediately and I swallowed one because it came off so fast, I was chewing super carefully as well. I wish I could give this a better review because it works great but the price + the time it stays on doesn’t justify buying it, I had to buy more after 1 day so I spent nearly 30 dollars in two days for 12 of them

I suffer from frequent canker sores, and they can be so painful that I can’t even enjoy my favorite foods. I tried the canker sore patches, and honestly, the pain relief was almost instant. It took a minute to figure out how to get the patch to stick properly, but once it did, it stayed in place and didn’t move around or peel off my lip easily. I’m curious to see how well it works the next time I get a canker sore on my gums. I recommend to anyone who suffers from canker sores!

Had a canker sore right on my tongue and was looking for more of a barrier rather than just temporary pain relief. This product does exactly what it says: it's a patch that sticks and covers the sore. I was impressed with the fact that it did stick considering the location. Downside: it's really short lived. Maybe about two hours. I'm not not sure if it was due to the location I had it placed, or if that's just the nature of the product. I'm not unhappy with it (it was a fantastic two hours!), and I'm willing to try them for different areas to see if it lasts longer, but I'm not sold on if this is THE product for me.

they are great short term and help with my canker sores a little but they don’t last very long and they are so unreasonably expensive (but i’ve bought these like 5 times and probably will continue to do so)

The only things that can get me through really bad canker sores. They do typically fall off if I try to wear them at night, but protect long enough for healing to finally start.
