New Mexico Dental Assisting License Practice Exam

The primary method used for polishing teeth in dental assisting is rubber cup polishing. This technique involves using a rubber cup attached to a dental handpiece, along with a polishing paste, to smooth and shine the surfaces of teeth after procedures such as scaling. Rubber cup polishing is effective in removing surface stains and biofilm, leaving the teeth with a clean, polished appearance.

Rubber cup polishing is favored for its ability to be gentle on dental surfaces while achieving effective results. The flexibility of the rubber cup allows it to reach various contours of the teeth, which is beneficial for thorough polishing.

While air polishing is a method that uses a jet of air and a bicarbonate powder to remove stains and debris, it is not as commonly used for routine polishing due to its more abrasive nature and the potential for over-spraying. Diamond polishing, on the other hand, typically refers to techniques used for more specific restoration procedures rather than general tooth polishing. Finally, handpiece polishing could encompass various methods but is generally used in conjunction with other polishing techniques and does not specifically designate the rubber cup method as a preferred choice. This is why rubber cup polishing stands out as the primary method in dental assisting.
