A Pittsburgh zoo's 2-year-old polar bear is recovering Monday after root canal surgery. Last month, zookeepers at the Pittsburgh Zoo & PPG Aquarium examined the bear after they noticed that he seemed lethargic. They discovered that Koda's quadrant mandibular canine - a big, fang-like tooth on the lower right side of his jaw - was infected. Dr. Tom Klein, a veterinary dentist at Ohio State University who operated on Koda, said the infection in the tooth could have spread to the jaw if it wasn't dealt with.

A Brazilian immigrant was arrested Tuesday for allegedly operating an unlicensed dentistry practice out of an Orlando apartment.

She owned up to doing procedures like root canals, X-rays, and crowns in the apartment.

Santa Claus has been hailed a hero by local communities in Damascus, Virginia after aiding the police in the arrest of a streaker. Father Christmas assisted the local police in catching a 35-year-old man who was running naked outside a police station on Monday.

A 200-year-old pair of false teeth that belonged to the Archbishop of Narbonne went on display at the Museum of London Friday. Archaeologists found the teeth in the coffin of the archbishop, Arthur Richard Dillon, while digging at the St. Pancras graveyard, where the Channel Tunnel's new rail terminus will be built. The dentures, which are made of porcelain and contain gold springs, were still sitting in Dillon's mouth. It is thought he may have purchased them from Nicholas De Chemant, a prominent Parisian dentist.
