Dentist Snapped A Drill In My Tooth

MRIs are done with essentially a big magnet that's exceedingly strong. If you have bits of (magnetic) metal inside you that aren't well secured (eg to bone) there's a risk they could become dislodged and cause damage as they're pulled through the tissue. In reality, a lot of medical metalwork isn't magnetic and it's usually anchored well enough not to pull through. But they always ask so the radiographer/radiologist can make the decision.

If worst comes to worst as you said you'll have the tooth pulled. Its no real biggie IMO i've had 4 out

Depends on which tooth it is..

No, it's because metal heats up within the machine to the point where it can burn the patient severely. Even makeup must be taken off because the metal particles in the powder can be heated and burn the skin and eyes. Medical metalwork is usually fine, but a drill bit?

That's a different reason - for certain bits of metalwork if there's a long wire and a current can build up E.g. ECG wires, pacemakers etc. I presume that's more common, but potentially less severe than a massive foreign body being ripped out through the flesh. The classical case is cerebral aneurysm clips, they can be metal and because they're placed very accurately, any small shift in their position (by the magnet) can lead to catastrophic haemorrhage. We have to ask the question, but as far as I know, those dangerous types of clips haven't been in popular usage for years.

It doesn't have to be a wire, there have been cases of iron in tattoos being heated and burning the patient. The metal gets hot enough to burn the skin akin to a soldering iron burn. Whilst it's not as severe as having the metal ripped entirely out, it's not exactly a minor issue and i'd be surprised if a drill bit would pass the all clear for an MRI screening.
