Obviously, he didn't use dental tape. After the file had been filed, he should put the tape down and let you bite down, which made him know the file. This is a guide... When you bite down the tape, it leaves a blue mark indicating which areas need to be corrected... Do a search for webm and review credentials or seek another dentist... Check, check, and check the dentists you plan to see before you do any work. It's best to pass word of mouth to your friends so that you have your own dental experience. Best wishes.
