Usher was in a panic after discovering he had left his dental retainer at the Chateau Marmont restaurant after having lunch with his mother Jonetta, a source tells Us Weeky. When the pair left the hotel, Usher realized he had left his retainer behind, removing it to eat. “I can’t find my retainer,” Usher said. “What are you going to do if they threw it away,” mom replied. “Pick it up from the trash?” Luckily, the singer found the dental device, though his rep insists Usher doesn’t wear a retainer.
