1. A mouthpiece component for use in an intra oral illumination system, comprising:
a core structure which defines at least one waveguide for receiving light which is directable at least partly by the waveguide along at least one light path of the core structure, wherein each at least one light path defines a propagation direction for light in a propagation plane;
at least one optical discontinuity which is configured to cause at least a portion of light propagating along the light path in the at least one waveguide to be transmitted out of the at least one core structure and continue to propagate substantially parallel to the propagation plane; and
at least one light redirection portion which is configured to redirect at least a portion of light which has been transmitted out of the core structure out of the propagation plane,
wherein the at least one waveguide comprises a first waveguide and a second waveguide which define a first light path and a second light path respectively, and wherein the first light path and the second light path intersect at an intersection portion, wherein the optical discontinuity is in or is adjacent to the intersection portion.
