A loop is formed by a bow having across one side a strip or blade. The bow has flexure and memory. The flexure and memory of the bow are imparted to the strip, enabling the strip to be either taut or loose, depending on the pressure exerted by the operator upon the bow. The bow is held and manipulated by the operator with the thumb and finger. The strip is positioned under tension. A holder for the device allows additional variability in the angle of attack of the strip, and facilitates quick and easy interchange of the strips. A holder avoids insertion of fingers far back in the mouth, where working space is limited.

An apparatus for separating teeth utilizing a base member having a first end portion, a second end portion, and an intermediate portion.

A lingual shield spans the distal portions of the first and second springs extending from the base member. A pair of tines overlap one another, one tine extending from the base member, the other extending from the shield. The first and second springs urge the meeting or overlapping of the first and second tines in the vicinity of gap for meeting place between a pair of teeth.

A device and method for applying dental composite matter to dental surfaces, such as cavities in teeth, gaps in teeth, or other deformations in tooth surfaces, or other applications to teeth, or appliances and devices used with teeth, such as crowns or inlays / onlays.
