After a week of what feels like dying from the dreaded Lurgy I have now started with a very sore gum/tooth. I've had wisdom teeth trouble before and corsodyl always improves things and sometimes catches it before an infection takes hold. I only have Some that expired in 2016. Please tell me this will be ok until I find someone to buy me a new one. I've used it already and it still has the same vile taste. Thank you mumsnet
