I picked up this Colgate mouth sore rinse after dealing with a stubborn canker sore and within a couple of days, I noticed a huge improvement. The 1.5% hydrogen peroxide formula creates a gentle, foaming action that really makes your mouth feel clean and soothed. The mild mint flavor is perfect refreshing without being overpowering and definitely not harsh like some other rinses. I also appreciate that it is alcohol free so there’s no burning sensation. After using it twice a day, the irritation and soreness went down significantly faster than they usually do. Overall, this rinse has earned a permanent spot in my medicine cabinet. Whether it’s a canker sore a bite on the inside of my cheek or just your general irritation. It really helps speed up healing highly recommend! Read more

UPDATE 6/28/22 I have continued to use this over the last couple years and the rinse is amazing. A few months ago I had a number of canker sores in my mouth and the pain & healing time reduced by using this rinse is amazing. I don’t always use it but when I have it’s made a difference. I use it religiously multiple times a day for probably two days out of having the sores and the pain is nonexistent for a little while. Then I’ll go to 2-3 rinses a day while they’re healing. I still use anbesol in between when needed but this totally works. Please get this and you won’t regret it. UPDATE 11/5/2020 I have used the rinse three more times today and my mouth feels ten times better. There's only one more sore in the back of my mouth that still hurts. The rest are there but are not painful and do not make it hard to talk or as difficult to eat. This is some of the best stuff. I also used one more OraSwift Lozenge last night and it helped a little. PLEASE get this for your mouth!!! 11/04/20 That's right. I have eight canker sores in my mouth all at once. One on each part of where my wisdom teeth already came out - so one on each of the four corners of my mouth, one on the left side of my mouth behind the jaw tendon about half the size of a dime, one in front of the tendon, one on the back of the roof of my mouth, and two more on the front of the roof of my mouth. These all developed over a period of about 3 days at once. I was in EXTREME pain on the night of 11/3/20. I was crying. I could barely eat, and what I tried to eat at my job while on a break hurt like you wouldn't believe. It felt like my wisdom teeth were coming in and bone was pushing through. When I got home I cried my eyes out, swished some of this stuff around for a minute, and put an OraSwift Lozenge on the left side of my mouth. The lozenge helped because it coated the one sore, and the rinse helped with inflammation. I get canker sores frequently and this has been a savior. I've now been using this mouthwash for the last 22-24 hours or so and my mouth is in way less pain. I have not had to use another lozenge, either. Here's my timeline of swishing: 11/3 10p 11/4 4a (randomly woke up) 11/4 10:15a (before coffee) 11/4 about 11:30a (after coffee, before lunch) 11/4 1:30-2 after lunch 11/4 About 7:50 after dinner NOW, for the mouthwash itself. It has a minty flavor but also like an intense listerine-type burn. Doesn't taste like alcohol though. The rinse itself foams up so I would pour a little less than what's recommended so you can swish it around your mouth still. PLEASE swish for one minute, it will make a difference. You will want to follow the directions and swish as you normally would with mouthwash, but for sure after eating anything. Even an apple or a single grape or whatever. Just do it, you'll thank me later. As a canker sore sufferer, this stuff has really done the trick. My mouth is not as inflamed, I can eat without as much pain, and I feel at way more ease without feeling like I'm starving. Speaking of food, because I have so many of them (this has never happened to this extent) I have been eating soft things such as vegetable soups and things like spaghetti cut up because they're easy to swallow and require little to no chewing. Please get this and use as directed and more. It will be so worth it, I promise you. Read more

This mouth rinse with hydrogen peroxide works well to help alleviate pain and aid in healing of mouth sores caused by viruses, jaw bites, etc. The taste is a minty flavor similar to other mouthwashes. Do not use this for any absess around teeth or open sores in the gum line as the hydrogen peroxide in the rinse could possibly cause a condition known as dry socket. This is an antiseptic mouth rinse only so do not swallow. I compared with the cost at a local Meijer supermarket and this was nearly $2 cheaper per bottle. Highly recommended. Read more

I have an autoimmune disorder that frequently produces small but very painful sores in my mouth. Unfortunately, one of the medications used to fight this disorder can cause oral thrush as well. It's not a devastating problem but can be really annoying. It shouldn't hurt to drink coffee, that blessed elixir of life. I have tried many remedies, (salt water gargles, mixing my own peroxide rinses) but nothing really worked well. I ordered this mouthwash, although I didn't really expect miracles. As with so many other things in my life, I was wrong. Really wrong. This stuff is awesome!! I got almost instant relief from the pain. Within a day or so of use, the sores faded dramatically. I use it now as a preventative measure. It's minty but not overpowering. Although it's a little pricier than most mouthwashes, it's well worth it. It shipped quickly and was well packaged when it arrived. It is now a valued member of my autoimmune toolbox. I won't run out of this!! Reducing the odd symptoms of my illness reduces stress as well and allows me to concentrate on healing. (Although the review process encourages photos, I'm not doing that. It's a bottle of mouthwash, not the Mona Lisa. And absolutely NOBODY wants to see a grainy, blurry photo of the inside of my mouth!) Read more

Colgate Peroxyl Antiseptic Mouthwash has been a lifesaver for my daughter and I with our braces. If you know, you know—brackets and wires can cause irritation, cheek sores, and gum sensitivity, and this rinse truly helps heal and soothe those areas fast. It doesn’t burn like other mouthwashes, which is a huge plus, especially when your mouth is already tender from adjustments. It keeps everything feeling clean, helps reduce inflammation, and speeds up the healing of any small cuts or sores that braces can create. I also love that it’s alcohol-free, gentle, and safe for everyday use without drying out your mouth. Read more
