In fact, if you're a hygienist first, you might be a better salesperson. You may also get a better base salary. There is a big difference between a health school and a "real world", and if you are going to pass a practical committee, I will do the work and get some real world experience. After you've worked for a while, I mean at least two to five years, so you might be depending on your health pay, maybe a little less. But at this point, you have no experience, and you have a higher product experience on the basis of sales.
Ps: if you actually walk into their shoes, it's easier to sell them to someone else.
