I knew about sunscreen losing its effectiveness after expiration, but that apparently goes the same for toothpaste and mouthwash. It isn’t really a ‘best before’ situation for these things as much as a use by date.
It can still be used after expiry. ie. toothpaste will still be a mild abrasive cleaner and mouthwash may remain antiseptic.
However the fluoride will no longer be effective or protect against cavities. (And the sunscreen will let you burn.)
Anyway. I just had the thought that as belts tighten there might be more people resorting to bulk buying or other cost effective measures, and wanted to share for others that didn’t yet know.
Generally toothpaste is good for two years from the manufacture date so buy accordingly. Or if an older tube is given to you by a friend, food pantry or shelter you might want to throw it away and buy a fresh one.
Toothpaste i feel like doesn’t really matter much for me since I use it every day and go through it so fast. And even if it wasn’t doing anything, the fact that it makes brushing more tolerable is a good thing. But sunscreen is a very useful reminder because I definitely hoard that shit for ages and only use it for maybe one third of the year. This was a good reminder to go through the dates on my many half empty bottles, thanks!
