dentist wanted

I just learned that they are closing my current dental office (which is in Watertown Square) in about a month. They're suggesting patients either go to Westborough, which is out past 495, or a Gentle Dental in Belmont, but my current dentist will be working entirely in Westborough. I can get to the Belmont office about as easily as to the Watertown one, but it looks like I'm changing dentists anyway, and am looking for suggestions.

I'm in Brighton, near the ends of the B and C branches of the green line, and being reachable by transit is more important than distance in miles as the crow flies.

I want somewhere that still takes some level of covid precautions (masking, air filtering, and/or good ventilation), and that won't have a problem with me only masking in the dental chair.
