@dedicto I got my 10th a few days ago, too! (I'm counting the initial two in 2020 as just one.)
And like you I mask and avoid crowded spaces. My dentist has windows that open, and they always open them for me.
No Covid infections yet, as far as I know.
There's also this, which I've been using to good effect. (Important trick: one edge has stiff plastic: put that edge over the •top• or your nose. Also: pre-stretch your upper lip before applying. & remember to inhale before speaking •through your nose•.
(& I also ask my carers to wear N95. Fortunately, haven't gotten any backtalk from them.)
I also, so far as I know (knock on wood) am a #novid

Dental care is something I prioritize, because I've seen what happens when one lets it slide.
Don't get me wrong, I was extremely angry when my dentist's office dropped precautions, & I let them know it.
