Found 2nd OctFound 2nd Oct
Use twice daily. Especially effecitve when used morning and evening after brushing. I found this really good and usually it costs a lot more than this. Free C&C





Been struggling to find this for quite some time, and Listerine themselves were as much use as a chocolate fireguard in assisting with my query.


Damn, I've not bee re-setting my mouth for years.

Oraldene mouthwash 200ml £1 poundstrecher Larne.
Get dealGet deal

nowadays i use hydrogen peroxide as a mouthwash - I started off buying the pre-bottled stuff eg but then realised you can buy more concentrated food grade in bigger amounts & water it down eg (water down 11% so it becomes around 4%) The main issue is that peroxide slowly decomposes into water & oxygen so you cant buy too much & you have to store it carefully eg out of the sun & preferably in a fridge I was finding with these other fancy mouthwashes that if I used them before i went to bed that I'd wake up with a nasty taste in my mouth & often also with a headache


Got some today, shelf edge says £1.99 scans at £1 EDIT: Lincoln store carlton centre :)


Great deal OP. I got some in Home bargains at £1.49 and that a was great price. Good to see Larne get a mention on HDUK as well. My Mother loves Poundstrecther in Larne. She'll be well impressed by this post. lol


This stuff is brilliant for sore throats. Gargle at the first sign and it kills off everything


Good find.

I love the death type flavour early in the morning, it wakes you up a treat. The original, and most mental of mouthwashes.


Listerine make some excellent mouthwash but this tastes and smells something like the tar used to repair roads


Horrible taste and dries out your mouth,

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.
