I was there to have my crown replaced, but I ended up in the emergency room having an X-ray. The dentist losses the tip of the drill and I accidentally swallowed the tip of the drill This is the first time this has happened to me. I thought it will be only two hours but instead I lost the whole day of work. Now I have to go back to do another X-ray to make sure that the the drill tip will pass and not stay in my stomach, otherwise it will cause an infection.
