I started a new job as a dental assistant recently. I am a foreign trained dentist.

The dentist sat me in his office and told me “between 9-5 and 9-7 you are mine. If a family member dies your family can call the office phone.”
This was his way of saying that you aren’t allowed to be on your phone during work hours.
It’s my first job as a dental assistant so I am on the slower side. I was assisting him and he said I should go and apply to the social security office for welfare because I am that slow. He has a sense of humor that borders on offensive.
He told me that he doesn’t know where I worked before and what was acceptable about the way I present myself. Now this is new to me because I am very well presented. My hair is neat my scrubs are ironed. (I was a prefect in high school for context) I have always had good deportment.
The practice has cameras everywhere. The operatories, the labs, the sterilization areas, the halls the waiting room, the kitchen/lunchroom. And he sits in his office and watches them during the day and you can be critiqued based on what he saw on camera.
No orange protective shields are provided in the office and he pressured me to look directly at the blue curing light while using it. My eyes have started getting blurry.

I am genuinely curious, since I am new to this country if this is normal.

EDIT: I resigned effective immediately. Thank you all for your insight
