the cyproterone acetate does list "dry mouth" as a side effect.
if this is the truth - that they're pushing for fillings because i can't get a scaling due to a lack of coverage - then i wish they'd be upfront about it rather than try to manipulate me in a dishonest way. i can probably get coverage, and that's a far better idea than drilling into a tooth that obviously doesn't actually need it.
i'll find out next week - i'm booked for a cleaning, let's see what they tell me.
