Must have
Colgate peroxyl mout rinse an excellent remedy for treating minor oral health issues. Great package. It opens and closes easily. The taste is fine for me but I wish it were a bit milder.

Poor Service
Wish I could truly give an accurate review of this item but as a 360 member who ordered this along with multiple other items that I kept getting texts beginning at 9 every hour that my delivery was delayed until at 4pm got last text saying my order was completely canceled. Way to go Target. Don't pay for 360 - they don't follow through on what they advertise.

quality for sure
Absolutely fantastic, gums feel so good after about 3 sessions of it about twice a day and I feel so good now thanks to your product. Personally I maintain a schedule now with it so I don't worry about it coming back. NOW, if I could only find your Product called MaxClean with SmartFoam I could really use the help in finding it in Red deer AB wherever you deliver to here would be really helpful. Thank you so much Steve Dooley

ive had braces for 2 years at this point, and i ran into some problems with my brackets early on. they were rubbing holes into my cheek and i was in a lot of discomfort. my orthodontist had recommended this and it’s so good. the taste isnt that bad, but its just what you expect from mouthwash. they’re all kinda icky. but all in all, this is the best thing for if your mouth is hurt!

Works great to help get rid of a sore throat quicker. It doesn’t burn at all and the mint flavor is mild. It does foam up when you swish/gargle it. The cap isn’t the best design and some mouthwash will drip onto the bottle unless you rinse out the cap first.

Extremely strong mouth rinse!!!
This mouth rinse was recommended by my dental hygienist. Do not use this if you have deep or large canker sores!! It burns immediately and is very painful!!! This stuff is extremely strong!!!

Great product. Better than other brands
I was planning on getting the oralB version because that’s what I’ve always purchased in the past but I saw this one and figured I’d give it a try since the oralB wasn’t really cutting it. I’m convinced this stuff is magic. As someone that suffers from mouth ulcers I’m so glad I tried this one instead. I can eat again!

Does what it says, doesn't break the bank.
I bought this product a few days ago after getting my gums and inside of my cheek damaged when my 2 year old shoved a pine cone in my mouth. For days the damage caused immense pain and swelling. I bought Colgate Peroxyl as a way to assist until I could get to the dentist. I was amazed by this product! By using it strictly as directed on the bottle my mouth was totally healed in just two days! This saved me a bunch of money in dental work and provided near immediate relief. By the 3rd use on the first day I was already able to feel a significant difference. It has a cooling effect that helped the pain immediately and its claim to fame is not joke, after a week of increasing misery Colgate Peroxyl was able to fix my mouth in incredibly short order all for a great price! Thank you Colgate.

Should be called Magic Mouthrinse
This is a wonderful product that has provided much relief when I was undergoing some allergic reactions to medication that gave me a very sore mouth.

Gentle
Really like this mouthwash! The hydrogen peroxide helps clean gently without burning. My mouth feels fresh, and it helps soothe small irritations. Will buy again.

Poirly designed bottle.
Poorly designed bottle. Instructions say to use half a capful and rinse…but when putting the cap back on, it spills and drips down the side.

Great for mouth discomfort
My back molar began to hurt Friday- Monday and even worse at night .. ibruprofen and Tylenol only make it bearable but throughout the day it was so uncomfortable. Bought this mouthwash and with one use it already made a difference!! I’m hoping it will work until I see the oral surgeon in 2 weeks!

Great for stress-related sores!
Periodically when I have excess stress, I get painful sores on my tongue that last forever. Once I started using this rinse, they clear up within a few days! Really recommend this mouth rinse!

Repeated purchase for many times
I have purchased this mouthwash for many times. It works very well when you have small wounds in your mouth. It helps recovery fast.
