Even when I am not actively seeking employment I keep my resume up to date. You never know when you may need it, and having it ready to go will make your life much easier should you or your employer decide it it time for a change. I also worry that if I don't add my new training or certifications to the resume I will forget to add them later.
Cover Letter: Make it good!
Tell a little bit about yourself, your philosophy on dentistry and your excitement about the possibility of introducing yourself in person
Delivery: If at all possible drop the resume off in person, make sure you look professional when you go to the office.
If you must fax or email the resume then I think a follow up call to make sure they received it is appropriate if they give a phone number.
This is a copy of my resume (click on "read more" below to see the resume)- I would be interested in any comments or suggestions that you have.
If you need some one to proof read your resume email it to email@example.com and I will let take a look.
The Resume: Sell yourself - you are great!!!
