A dental fulcrum composed of soft material, such as foam, containing a slit for the insertion of incisors, and used as a pivot for scaling, or other treating, teeth by an oral hygienist or dentist. The dental fulcrum protects the fingers of an oral hygienist or dentist from calluses, or loss of sensitivity over time, while at the same time providing friction to reduce the risk of injury caused by fingers slipping on wet incisors. The device may be disposable or reusable, depending on the material used. Foam provides the additional benefit of absorbing saliva to further reduce the risk of slippage.
