The filtering device includes a transparent filter member for blocking optically harmful light emitted from a tip of a dental curing device, and a rotational bearing having an inner component defining an opening for receiving the tip. A retaining device holds the tip substantially centered inside the rotational bearing and substantially rotationally stationary relative to the inner component of the rotational bearing. A counterweight below the rotational bearing causes the filter member to remain in an upright position above the tip when the tip of the curing device and/or curing device itself is rotated.2/5 0 Dt (-% / K t / W4 C"4 LLk
