Such a relieve for canker pain.

I occasionally get a canker (usually on the side of my tongue) and I place one of these patches on it and it is pretty much gone overnight. The patch dissolves naturally over a day or two. I would be in pain for days if I did not use this canker patch.

Wow. It works!

This is an amazing product. I had a nasty canker sore for 5 days. Kept getting bigger because I kept biting it. Used this patch and within 15 minutes I felt relief. As of now I've had the same patch on for 9 and half hours and it's still working. Able to eat and drink normally. Wish I found these sooner.

The before/after is AMAZING

I dont get canker sores very often but when i do it feels awful. I used to do the ole “swish with warm salt water” which usually works….until it doesnt. I had a sore growing between my gum %26 bottom lip (right where they meet). It was growing for days %26 no matter how much i swished, it just kept growing. It ended up being too painful to talk, eat or drink. I was MISERABLE. I did some research %26 came across patches. I bought these a few days ago %26 tried it the day it arrived. At first i struggled for the tab to stay in place (im guessing due to the difficult location). Finally i broke the tab in half %26 it stayed. After a few hours i swelled up %26 i FINALLY had relief. I was able to eat, drink %26 talk. I kept the tab in for 8 hours before removing, it stayed in place the entire time. It had been 3 days since i put my first tab in %26 i havent had to put another one in since. I noticed i no longer have pain in the area %26 its finally starting to heal. 10/10 recommend!!
