Best way to heal canker sores

originally posted on viewpoints.com

For as long as I could remember, I have been using Colgate's peroxyl mouthwash for all my canker sore issues. We've all been there, eating away and suddenly biting the side of your mouth or lip. A day goes by and a huge canker sore forms! I use this mouth wash as soon as I bite my lip, or as soon as a sore forms. Of course, I practice good oral hygiene, most especially when I have a canker sore. I brush my teeth after every meal and rinse with the peroxyl each time. Usually with that procedure, my canker sore disappears in approximately two days. It truly works every single time. The only thing I wish I could change about the peroxyl is it's taste. It is very obvious you are rinsing in hydrogen peroxide. While swishing it around in my mouth, I could feel the foam ... MoreFor as long as I could remember, I have been using Colgate's peroxyl mouthwash for all my canker sore issues.

It took a while getting used to. I think, however, after skipping several good meals because of a canker sore, you wouldn't mind giving it a shot.

Colgate Peroxyl is great for helping to heal mouth irritations!

It's a little more expensive than regular mouthwashes but it's more than just a mouthwash. It's an oral healing agent. When I used **Colgate Peroxyl **the first time, it almost felt like a "stinging" type feeling but it didn't hurt. Kind of like when you put peroxide on an open wound but sloshing around in your mouth. The taste set me back too but i didn't really expect it to taste like pizza. After I gargled and spit, my mouth felt refreshing and actually quite soothing. I used **Colgate Peroxyl **for many months until my oral surgery. Since my oral surgery, I still keep **Colgate Peroxyl **on hand. It works great for canker sores. If you have had a canker sore, you know how painful they can be! We get them regularly in our house and use **Colgate Peroxyl **to gargle with to help relieve and heal quickly. I strongly recommend **Colgate Peroxyl **if you have any dental/mouth/gum irritations that you need relief and healing from! Env: development

Colgate peroxyl, Antiseptic Oral Cleanser wth Hydrogen Peroxide,
18 October 2011

Env: development My daughter has braces and she had a loose wire that was scratching her mouth. Unfortunately this happened on Saturday night and she could not get in to see the orthodontist on until Monday morning. By Monday morning the inside of her cheek was pretty torn up. The orthodontist recommended that she get some Colgate Peroxyl, this would help the scratched up cheek to heal faster than if it was just left alone. The Peroxyl is created for canker sores for the most part but it also good for any type of sores inside the mouth. The peroxide in the liquid helps to clean and bubble up the mouth sores, while it is helping them to heal faster it also makes them feel better, by soothing them. It comes in two different flavors the original flavor and a mint ... MoreEnv: development My daughter has braces and she had a loose wire that was scratching her mouth.

It comes in two different flavors the original flavor and a mint flavor. We got the mint flavor. IIt comes in a 8 oz container for about $6.00. You can also get 16 oz bottle for about $10.00. You can use the formula up to 4 times per day. You use 2 teaspoons of it at a time and swish it around your mouth for about one minute then spit it out. Kind of like you would do with Scope. Do not use in anyone under 2 years of age, and you should supervise your kids when they use this and make sure they don't swallow it, even though it is alcohol free. The taste is tolerable. It is certainly not great but it is OK enough to keep in your mouth for the 1 minute required. Env: development

Env: development Colgate Peroxyl, Antiseptic Oral Cleanser Hydrogen Peroxide is a very powerful product. I purchased it because I had a gum infection that I was trying to cure. It is a know fact the hydrogen peroxide is good for cleaning and fighting infections, but you can't use it in your mouth straight out of the bottle and it is hard to dilute it correctly so that it will still be effective. Colgate Peroxyl, Antiseptic Oral Cleanser has the perfect dilution of Hydrogen Peroxide, so it takes the guess for out of it. When you use it , you get the fizz that you would expect when you use hydrogen peroxide; so you know its working. This is an antiseptic product not a mouthwash to be used for freshening, so if you want fresh breath you will need to use another ... MoreEnv: development Colgate Peroxyl, Antiseptic Oral Cleanser Hydrogen Peroxide is a very powerful product.

My dental office used this for a while. I liked it and found it could be purchased at most any grocery or drug store. I have purchased it and like using it. But I find the cost off the charts. I will be going back to something more reasonable in price. The product is way overpriced.
