Perfect for holiday. Thanks OP (y) I was in a shop opposite Robert Dyas when I spotted your post, so it would have been rude not to get some :D

Tesco half price Listerine Advance Defence gum treatment mouth wash - £3 @ Tesco
Found 27th JunFound 27th Jun
Just saw it in store and grabbed 4, they are very very good with gum diseases. Normally cost £6 ish so this is a bargain as I use it everyday. Hope it will help someone.

It's rare to see this particular type of Listerine on offer. Recommended by my dentist, she was very insistent I need this particular one. Good find, will stock up!


I bet you have very healthy gums and don’t need this mouthwash. For me this one saved my gums. Just checked Amazon and they are even pricier


Have you really ever seen, let alone paid, £6 for mouthwash in the past?!Seems like £3 is about right ...

The Tesco website seems to suggest that this one isn't in the £2.50 offer, so it seems like a deal to me (if you want this specific Listerine formula).

The numbers are strange because they marked it up by 45% so they could mark it down again.

I think you will need more than mouthwash to get rid of THAT taste. Perhaps deal with the cause and not the symptom e.g. Harpic Rim Block Citrus Hygienic

'telling me it causes pain is nonsense'. Well obviously you speak for everyone in the world, I was just speaking from personal experience, I forgot that you are the judge of whether pain is of an acceptable level to complain about. The inflammation of my gums was also my own fault, even though my dentist said it was because of the mouthwash. I can only apologize and hope you will not judge me too harshly for my foolishness. If it's good for cleaning floors it's good for your mouth, tha's what I say.


Childbirth causes pain but people still do that lol. It doesn't cause pain mate it burns a bit when you spit but that's not pain and you still haven't said how it destroys your gums or can't you answer that? I personally like using Listerine but obviously if there is evidence to support what you said then I wouldn't use it but telling me it causes pain is nonsense


If something causes pain when you use it (which this does), it's probably not good for you in the long run.


But it says you can use mouthwash just not straight after brushing you have to leave it for a while. Hmmm yeah everything causes cancer these days doesn't it?

I'm not promoting the product but having tried all of the others which keep my breath fresh for a very short time, this keeps mine fresh for around 9 to 11 hours, just short of the claimed 12 hours. Enough said.. If you think the other cheaper ones work for you, go buy them...


(cheeky) Ok Gummy....I'l take you word for it


It only has cytylpyridine as active ingredient. Same as most washes


In my experience I would never trust whatever a hygienist or a dentist says.


Because its the only one that actually works. It kills off the bad bacteria causing bad breath rather than a rinse that just leaves a nice smell for a short while.. My hygenist said that my teeth and gums are perfect but I just happen to have the kind of mouth that cultivates the bacteria resulting in eggy breath...
