Is it possible to get hired for dental assisting without experience?

A dental assistant with no experience can find employment with a high school diploma if they find a dentist or clinic that is willing to provide on-the-job training. The qualifications that you need to perform specific dental tasks vary by state. ... DANB offers a National Entry Level Dental Assistant (NELDA) certificate.

Every dental assistant gets on the job training from somewhere. 

Some might. Particularly if you offer to volunteer the first month for free or at a reduced rate. 

In the "old days" many did train on the job, but not so much now because there are plenty of professionally trained grads, there is not enough time for a dentist to do that, and stands of care often require professional training. They might take a new grad and have someone "tweek" their training for the practice, but the odds of finding someone to completely train someone is negligible.

I guess it depends on the dentist ….Not disputing Keith’s answer, but I will give another side of that.

My Dad was a dentist and had several practices in Chicago area, and Arizona . Other than hygienists about 80% of his new hires for chairside (dental assisting) were people he met (waitresses, etc…) with no experience.

He said every dentist is different and prefers things a certain way. That it was easier to teach a person how to do it his way, rather than go through the process of unlearning what they learned in school and reeducate them on the ways his practices did things.

No, there is too much work to train on the job.
