I had a permanent metal bar on my teeth and was told to remove my piercings but that the bar should be fine… what’s the difference? they’re both metal i thought?

Your braces were likely made of titanium. Titanium is not ferromagnetic, meaning the magnet will not attract it.
What MRIs can do to nonferromagnetic metal is heat it up. The strong magnetic field produced by the MRI creates an electrical current in the metal, heating it up. That’s why you need to remove any extraneous metal, especially if you’re not sure if it’s ferromagnetic. Certain medical equipment that can’t be easily removed (like braces) are an accepted risk. If you had something like a steel plate implanted in you (steel is ferromagnetic) you would not be allowed to take an MRI.
