I got some from the dentist last year and never used it. I want to use it now and am wondering if it is still good or if it expires?
This depends on whether or not you kept it in the refrigerator. If not, I'd assume the potency is down, but it's not going to hurt anything to use it other than the inconvenience. If it was me I'd give it a go since you've already paid for it. Good luck!
HELLO,READ THE PACKAGE. IT SHOULD BE WRITTEN THERE.
