The odor of poor dental hygine?

Seriously though... just be honest and talk about why you chose that field... after all you don't have that much practical experience to say much more.

What should I say I really doesn't know am new to this

That's why I suggest talk about why you chose that field. There IS a reason you picked that and not something else.

If you speak from the heart it will appear genuine.. if you repeat someone else's words its going to sound exacly like that.. someone else's words.

So true Smoothy, it has to come from the heart. There has to be a reason to have chosen the field of dental assisting since there are thousands of other occupations to have chosen. Why did you choose dental assisting??
