Gregg filling instrument is a dental tool used for placing and removing excess temporary filling material. Useful in cavity preparation and to shape composite. This is a coated instrument, not meant for amalgam. Plastic Filling Instruments are highly polished stainless steel dental instruments used for composite placement and contouring. Off-angled blades of the 4/5 Gregg allow easy adaptability to mesial and distal surfaces of posterior teeth, providing increased interproximal access and better visibility of the working area.
