Review: Great product - This is great stuff. I do get gum ulcers/blisters sometimes but haven't had any since using this. Also seems to be good for keeping tonsil stones at bay. Wouldn't say it keeps your breath lasting fresh, but I don't suppose that's the main aim

### ⭐⭐⭐⭐⭐ This is an absolute lifesaver - a must-have for every bathroom cabinet!
*by D***N on 11 June 2025*

I feel like I've tried every trick in the book for those awful, painful mouth ulcers that seem to pop up from nowhere. You know the kind – they make eating and talking a misery for days on end. On the recommendation of my dentist, I picked up a bottle of Colgate Peroxyl, and I am so incredibly glad I did. It’s not an exaggeration to say this has been a total game-changer for me. I'd been struggling with a particularly nasty ulcer on the inside of my cheek, and after just one day of using Peroxyl, the relief was immense. The sharp, stinging pain had dulled to a much more manageable ache. By day three, it was practically gone. I was genuinely amazed. What I really like is the unique, gentle foaming action when you swish it around your mouth. It feels like it's actively cleaning and getting right to the sore spot without being harsh or aggressive. The flavour is a pleasant, mild mint – nothing like the fiery, alcohol-based mouthwashes that can feel like they’re doing more harm than good. Because it's alcohol-free, there's absolutely no painful burn, just a clean and soothing sensation. I've since used it for general gum irritation when I've been a bit overzealous with my brushing, and it has calmed things down beautifully overnight. For anyone in the UK who suffers from occasional mouth ulcers, sore gums, or any minor irritation from braces or dentures, I honestly can't recommend this enough. It provides fast, effective relief and has earned a permanent spot in my medicine cabinet. It’s one of those products you'll be incredibly thankful to have on hand the moment you need it.
