My dentist gives me samples when I get my teeth cleaned. I like it but concerned about the teflon

That's how I found out about it too. Teflon is supposed to be pretty chemically inert at normal temperatures, but I'm not a chemist and can't personally vouch for that. It can release fluorine at higher temperatures (like in non-stick cooking pans),so that's where I would be most concerned about it.
