I am far from an expert in these matters, but would advise against both teasing back and saying explicitly that you interpret the teasing as “treating me worse than usual”.
[EDITED to add: To be clear, I mean “don’t do both of these together” rather than “both of these are individually bad ideas”.]
Because one is playful and the other feels hostile. Doing both at once won’t give you a clear sense of what her response is to either. Do them in separate encounters.
Apparently even with my edit I wasn’t clear enough. Letting A be “tease back” and B be “mention that she seems to be treating you worse recently”, I wasn’t saying

Why not both? What could go especially wrong?

Why is teasing back a bad idea?
Apparently even with my edit I wasn’t clear enough. Letting A be “tease back” and B be “mention that she seems to be treating you worse recently”, I wasn’t saying
“don’t do A, and don’t do B”
but was saying
“don’t both-do-A-and-do-B”.
