Abstract: A light emitting apparatus for curing a photocurable dental prosthesis in a patient's tooth that comprises a LED carrying part connected to a handle. The LED carrying part comprises a first plurality of LEDs directed to a first side of the tooth, and a second plurality of LEDs directed to a second side of the tooth. The present invention also relates to a method of curing a photocurable dental prosthesis in a patient's tooth, in which a light emitting apparatus is provided that comprises LEDs that are mounted on a substrate, the substrate being covered with a clear coating embedding the LEDs, and the LEDs being placed so proximate to the photocurable dental prostheses that the smallest distance between the outer surface of the clear coating and the outer surface of the photocurable dental prostheses is less than 2 mm.
