Licensing Prerequisites for Dental Assistants vary by state. In certain states you do not even have to be licensed, only show that you’ve finished a Dental care Assistant course of on the job training. If your particular state gives a certification option, it is in your favor to obtain licensing as you will have a better chance of getting employed over those that aren’t licensed. Usually, you may also assume to be compensated more than those who are qualified, but not licensed. There are no Federal Guidelines in regards to Dental Associate certification. Everything happens on the state level.
