Can someone help me write a cover letter for a dental assistant?

[Kelly]

I need help to write an amazing cover letter for a dental assistant job. I have no experience but the job doesn't require it as they will train you. It has been a passion of mine to have a career in the dental field but don't know which one is right for me so i figured I would start out small with a dental assistant to see if I actually like the field. I really want this job because I have been wanting to do something like this since I was 10. (I'm now 21) PLEASE HELP! Thanks
