Went to the dentist today, and they fixed the tooth (within a matter of minutes, as usual) despite a pretty big chunk having broken off.

Asked them to wear FFP2 masks (I brought some) due to the immunosuppressants, and it was no problem at all, and they first went off to check if they still had any in stock themselves.

It's really nice to have a competent and pleasant dentist practice nearby like this, literally around the corner.
