I found the dentist, assistant & receptionist to be helpful & friendly, I also found that my dentist & the assistant can take a joke.
EXAMPLE: Just before giving me the numbing shot my dentist told me to let him know if it was too painful. As a joke I decided to flinch "big time" both he & assistant JUMPED. I started laughing & then they knew it was a joke.
I prefer my dentist & assistant(s) have a sense of humor. When they do, I leave the office with a crooked smile instead of focusing on the procedure, numb gums & swollen cheeks @->---
