I'm simply amazed at the way digital technology is advancing these days. I just got back from my cleaning and six month checkup at the dentist. I was due for X-rays so she draped the lead gown over me and pulled the X-ray machine over. But she went over to the cabinet where the computer monitor sits and grabbed a little black puck that was plugged into a USB port mounted on the side of the cabinet. She asked me to open so I did. She placed the puck in my mouth, aligned it and said "bite down". I did and she left the room, pushed the button, instantaneously an X-ray image of my teeth appeared on the monitor sitting on the cabinet. Simply amazing!
After my cleaning I told her that I was having a bit of a sensitivity issue with one particular tooth. She then grabbed what looked like a small electric toothbrush that was also connected to a USB port. She stuck in my mouth and took three or four closeup high-res pictures of the tooth. They too immediately showed up on the screen. This stuff is pretty awesome!
