The good consists of a pretty fun work environment but this completely depends on the dentist who manages the office. In my experience, I worked with a very strict, uptight and sometimes mean dentist who made the job itself stressful.
The pay is inconsistent among your peers and sometimes unfair. Someone who does the exact same work as you will earn more or less.
Pretty fast paced depending on the location but overall busy. It can be stressful if you work with other assistants who aren't pulling their weight which was a huge issue when I worked there.
Management doesn't really seem to hear you when they ask for feedback or take your concerns into consideration.
Your first year you will receive no PTO and once you do, it's only 5 days worth of vacation. The longer you work there, the more vacation you earn but it can take a while.
Health insurance (dental/medical/vision), 401K, long/short term disability, opportunities for raises.
Lunch is inconsistent depending on how busy the day is, ranging anywhere from 30 to 60 minutes. Closers often stay late due to the high volume of patients at the end of the day. Schedule also varies week by week. One day you could work 8 to 5, another day you could work 9 to 6 so it's a bit unpredictable.
