An optical converter assembly includes a housing, a securing mechanism, and a light converter. The housing defines a first opening that receives part of a light-emitting portion of a dental curing light when the housing is selectively secured relative to the light-emitting portion of the dental curing light. The securing mechanism selectively retains the housing relative to the light-emitting portion. The light converter is comprised of a phosphor material and secured relative to the housing such that input light having a first set of wavelengths and radiant power emitted by the dental curing light is received. The light converter converts the input light to an output light having a second set of wavelengths and radiant power and to emit the output light. The input light includes a blue light and an ultraviolet light that polymerizes a dental material. The output light may be a white light.
