Two new teeth were implanted into singer Steven Tyler's mouth by a dentist in Paraguay after he lost them in an accident. The dentist, a woman named Maria Bastos, called into a local radio station today, claiming the singer is “doing splendidly” after the procedure, reports tmz.com. Tyler, the lead singer of rock band Aerosmith, collapsed and smacked his face in a hotel shower on Tuesday, knocking out two teeth.
