Doctors have extracted 526 teeth from the mouth of a seven-year-old at a hospital in Chennai. The doctors at Saveetha dental college and Hospital said that the the boy was brought with a swelling in his lower right jaw. An X-ray and CT-scan of the boy's lower right jaw showed a lot of rudimentary teeth following which the doctors decided on the surgery. Though some were very tiny particles, the doctors said, they had the properties of teeth. It took five long hours for the doctors to remove all the minute teeth from the sack. "It was reminiscent of pearls in an oyster," the doctors said.
