What is the most common technique utilized for stain removal in dental practices?

Rubber cup polishing is the most common technique utilized for stain removal in dental practices because it is a highly effective method that combines a polishing paste with a rubber cup attached to a dental handpiece to remove extrinsic stains from the surface of the teeth. This technique allows for a thorough and controlled polishing process, helping to achieve a smooth enamel surface while effectively removing plaque and stubborn stains caused by food, beverages, and tobacco use.

Air abrasive polishing, while effective in some situations, is less commonly used for routine stain removal because it can be more invasive and requires specialized equipment. Hand scaling is primarily used for the removal of calculus and plaque from tooth surfaces but is not specifically aimed at stain removal. Ultrasonic cleaning is generally used for more extensive oral health treatments and may not be the best choice for everyday stain removal as it targets larger deposits rather than fine stains.
