    I have been suffering for the last few weeks with a canker sore on my tonsil, it was extremely painful and over the course of a week it felt like it got worse and was starting to affect my sleep. most canker sores disappear over a week or so but after 2 weeks it hadn’t calmed down, I looked at a lot of products and noticed an earlier review where someone said to use this mouthwash around 4 times per day and pair with anbesol for the pain. Day 1 of this combo was a world of difference, pain went down to zero and I could eat without feeling like I had razor blades in my throat, I have kept on this and now im feeling like im back to normal, the canker sore isn’t quite gone yet but the size has dramatically reduced
    I can’t stress enough how good this mouthwash and the anbesol have worked

    Great rinse, and doesn’t burn sore areas or post-surgical areas (reason I purchased). Gentle mint taste with a bit of “peroxide” ish taste that isn’t bad at all – I actually like it because you know you are being sterilized, and again I purchased for post-surgical reasons. Helped alleviate minor pain as well. Highly recommend

    After a mild bout of oral thrush, I bought this for my husband and within 2 days it was gone! He likes everything about it. For me though, I use the Unflavored type for sensitive mouth. I love that product so when hubs developed his problem I knew right where to look. This is flavored but it’s not the bright minty blue or emerald green kind commonly seen. It’s a very mild, almost not minty yet it is. Either item is great as this is a really good product line.

    This is basically hydrogen peroxide (HP). Same percentage as drugstore and food safe HP cleaners. It has other things in it, but the HP is what works. I also use baking soda to scrub my tongue when my sjogrens acts up and toothpaste burns my mouth.
    For canker sores, I swish colloidal silver in my mouth for a few minutes (then swallow). I may repeat this the same day or next day. The canker sores are gone or 90% gone the next day.

    When my son had a mouth sore he acted like it was the end of the world. A quick Google search led me to online reviews about the ingredients that work best for mouth sores, and this mouth rinse fits the bill. It was effective and the flavor wasn’t as bad as we thought it would be.

    Wow I am actually quite impressed only used it a couple of days and canker sores in my mouth were gone and also when I was using it it made the canker sores not hurt when I drinked or ate anything with citric and the container is much bigger than I thought so will last a while for future needs
