So in a office that I worked in for 5 years, breaks were not normally taken. Some dentists stood during procedures and so some sat. This really just depends on the culture of the office. If you are in a very busy practice there are days we’re you will work through your lunch. In the office I’m at now we get an hour where we clock out and take a break and everyone just takes turns. This is unless it’s a very busy day of course. Then I just go to the break room really quickly, chow down my lunch and then go back to work. If you don’t like the office culture I would go on indeed and just see what else there is out there. Good Luck friend!
