Abstract
A dental polishing applicator for use with a rotary dental handpiece and method of using the same which is characterized by a collet portion and a removably mounted, disposable single use tip portion. The cylindrical collet is adapted to be removably mounted to conventional dental handpieces and includes an opposing end adapted to removably receive a shaft portion of the applicator tip portion. Preferably the tip portion comprises a relatively very small cylindrical shaft provided with a conical polishing end which is designed to permit access to the more difficult to reach areas of tooth anatomy. A preferred material for the tip portion is plastic made of a multiplicity of fibers axially aligned, adhesively coated and pressed together to form a cylindrical, unitary piece which exhibits good properties to apply polishing compositions to teeth and tooth restoration materials and sufficient strength in small diameter configuration for safe usage within the oral cavity at rotating speeds between about 1000 to 10,000 rpms.
