Do you get canker sores in your mouth when you finally start riding outside after a long indoor trainer season? I do. I’ve had to battle them every year.

Cycling in the cool spring air with all of that pollen in the air is a recipe for canker sores. I get them every spring once I get outside. Typically, we ride with our mouth open to get as much air to the lungs, and eventually the muscles, as possible. Riding with your mouth open all that time, believe it or not, can cause canker sores. They’re annoying and painful.

For years I used to rely on rinsing my mouth out in the morning with hydrogen peroxide. It works quite well but I always wondered if it was damaging my teeth. Unlikely, but possible – technically, hydrogen peroxide is acidic.

This year started out just like any other. I was rinsing with HP every morning and when I finally got let out with decent weather, we ran out of hydrogen peroxide. Within a few days I had three small canker sores. Now, if you’re a mom, at this point you’re thinking, “well you need more fruit”. Actually my fruit consumption always picks up in the spring – especially for bananas, apples and oranges – so that’s not it. Anyway, that Friday, my wife and I went to the grocery store so I could pick up some peroxide and she could check out the clearance aisle. While in the pharmacy aisles, I happened by Listerine – I’ve always loved the way my mouth felt after a good swish, so I picked up a bottle. Then, my wife suggested the non-alcohol version. Listerine isn’t a trigger for me, but it is for my wife so no alcohol it was.

When I got home, I started with the peroxide immediately to kick the canker sores. Then, after 30 minutes or so, I went in and swished with Listerine… and it was just like I always remembered (the taste and feel are no different with the no alcohol version). It was glorious.

And the next morning my canker sores were almost entirely healed. I did the hydrogen peroxide/30 minute wait/Listerine again. The next morning the canker sores were gone. I’ve since eliminated the hydrogen peroxide and am just sticking with the Listerine. The canker sores haven’t come back and my mouth feels fresh all day long. While hydrogen peroxide has been fantastic, I’m smitten with Listerine for now… it seems to work a little better and my mouth is happier for that.

    Thats odd, I used to get them a lot when I was young, mostly from eating to much candy.

    That’s my favorite Candy, but never have I got a Canker Sore. I have had at times had large consumptions of them too. My husband’s best friend and I love them the same. So when we all get together Dan and Lisa eat many! 🤣..
