Latin American here: my coworkers used to (note: I'm remote now, that's why the past tense) brush their teeth after lunch, so if they also brushed in the mornings and before going to bed, that'd make it three times.
I didn't though, I'm not taking my brush & toothpaste to a public restroom at the office.
It’s okay if you don’t, like, dip your brush in the toilet or place it in a dirty counter, and miles cheaper than paying for dental treatments. And it’s not like you’re taking your everyday brush and paste with you daily, right? You keep a secondary set at the office?
Like I said, I didn't brush my teeth at work. When I went to the office, I tried to go in and out of the restroom as fast as possible, touching as few things as possible, and didn't linger to do things like brush my teeth, eat or play chess.
I didn't keep anything at my office, there were no lockers, no drawers, and the desk itself was messed with by the night cleaning crew.

You don't need to brush your teeth after every meal, that's a cultural thing. As long as you brush when you wake up and before you go to bed, that's ok.
I've been in some dirty public bathrooms, but those were typically in the expected places like bars and the like. However, this is starting to sound like you just have a mental thing about public restrooms. Not that I'm a therapist or even play one on TV.
Brush your teeth three, four or as many times as you like! As I said, beyond the minimum it's just a cultural habit. I knew one person who wouldn't consider her tooth-brushing complete if she didn't also brush her tongue, then removed "stuff" from her inner cheeks with a spoon... each time. (It's not a common practice, before you ask). She wasn't a dentist or a doctor either, I think she was a school teacher.
The overreaction thing is just your own baggage. Seems like a lot to extrapolate from so few words.
