What is the function of a rubber cup in dentistry?

The rubber cup is utilized in dentistry primarily for polishing teeth using abrasive materials. This device, often attached to a dental handpiece, rotates and allows for the effective removal of plaque and stains from the surfaces of the teeth. The soft, flexible nature of the rubber cup helps to reach contours and interproximal spaces, enhancing the overall cleanliness and smoothness of the tooth surfaces after a dental cleaning or treatment. Utilizing abrasives in conjunction with the rubber cup contributes to the removal of surface deposits, promoting both aesthetic appeal and oral health by making teeth less susceptible to future plaque accumulation.
