Hahaha...I have a Dentist friend who when I asked that, looked at me with a gleam in her eye and said “Yes! Oh, when is your next appointment?”
(Actually, her favorite dentist related movie is “Finding Nemo”...she says the dentist part is very accurate!)
I said “Is it safe” to my dentist when he hurt me once. He got pissed and said he really goes all out to make it painless.
I really felt bad for the guy. He was hurt. He has come to appreciate my sense of humor (and my dental plan.)
