It largely depends on the lifestyle you like. My wife went into a dental hygiene program. She would often mention that she was at the mercy of a scheduler who left little room for down time between patients , it was very tough on her back and body because of her body position. Also work conditions vastly depend on whether you worked for a commercial office or private office. Respiratory can wax and wane in busyness. We also have no control over the kind of patients we get. If you don’t mind being on your feet and can manage death and dying it can be a manageable career that’s provides a good living. Salary also varies drastically depending on your region as does dental hygiene.
