Which of the following describes the correct technique for polishing teeth?

The correct technique for polishing teeth includes considerations specific to the type of surfaces and materials involved. The choice of limiting polishing time to 30 seconds on esthetic restorations is crucial, as extended polishing can lead to the unnecessary removal of material, altering the restoration's appearance and efficacy. Esthetic restorations, such as composite materials, are more susceptible to wear and damage, and prolonged exposure during polishing can negatively affect their integrity and aesthetic appearance.

This time limit is a widely accepted practice among dental professionals to ensure that the surfaces are polished effectively without compromising the restorative materials.

The other options do not align with effective polishing techniques. High-speed equipment can create excessive heat and cause damage to teeth as well as restorations. Polishing sequences matter, but they are not strictly limited to anterior to posterior, and in fact, the polishing motion should follow the natural contours and anatomy of the tooth. Finally, polishing without any abrasive materials would be ineffective, as abrasives are essential for achieving the desired smoothness and shine on tooth surfaces.
