Dental Hygienist here. Something I’ve realized is about half of my patients prefer little to no small talk during a cleaning, so knowing that at least puts me at ease that I don’t have to force a conversation with everyone. And like others have said, what people care about most is how well you do your actual job, whether you stutter or not. And recently I’ve found that forcing myself to smile (just a little bit) before words I would normally get stuck on has helped a lot. Not really sure why it works, but behind a mask I can practice getting my facial muscles into different positions to help with different sounds.
