Question by Astronaut: Is expired chlorhexidine mouthwash safe to use?
I know I shouldn’t but I have a large and horribly painful ulcer on the inside of my lip. It’s to the point of making my teeth hurt. Orabase is no longer numbing the pain for me. I have old chlorhexidine from a past surgery. It’s about a year old. Is it okay?
