Multi-wavelength dental light curing guns or devices are disclosed. The multi-wavelength dental light curing guns or devices include a user handle attached to a light source support. A first light source is mounted on the light source support and is operable to project a first light beam of a first wavelength along a first light path, the first wavelength being capable of initiating polymerization of a first photopolymerizable dental composition. A second light source is mounted on the light source support and is operable to emit a second light beam of a second wavelength along a second light path, the second wavelength being capable of initiating polymerization of a second photopolymerizable dental composition different than the first dental composition, wherein the first light path does not intersect the second light path. |
