What do I entail for a MRI?

I'm getting a MRI soon for my head. I know not to wear metal, but I had dental work done so I now enjoy a metal spacer in my mouth. Will that affect the MRI results? Will I be allowed an MRI? What else should I know before getting one, like do I involve to do anything special?
Answers:
The metal spacer might limit the quality of the MRI scan. Metal distorts the magnetic paddock that the MRI machine generates. But you really won't know the extent until you get the scan done.
