OKay this LOOKS like a good buy at 40p or thereabouts doesnt it?
I bought some once when I was on an extremely tight budget. I Will NEVER inm ylife buy this product again!
It does not in anyway protect your teeth! It doesnt even have any fluouride in it! Using this is like rinsing your mouth in vinegar it basically strips away all the goodness of your toothpaste and leaves you teeth open to decay etc>
My dentist went NUTS at me when I told her I had once used this. She said it is of no benefit at all and quite probably does more harm thant good, This is NOT what you want when you are trying to practice good oral hygeine!
My dentists advice was never ever buy a toothpaste or mouthwash that does not clearly say FLUORIDE on the front of the bottle or on the front of the box. If it doesnt say this it will not be a good product, and to stick with products that do have that on them>
This is not to say ALL value / budget range mouthwashes are no good you dont have to pay the £4 odd a bottle I have seem mouthwashes cost.

Also the taste of this is HIGHLY unpleasant. I cant even begin to describe it since i have never tasted anything so bad in my life before!

My advice walk past it on the shelves and buy something slightly more expensive it will be worth it in the long run
