Which is the most common technique for stain removal?

  1. Brushing

  2. Flossing

  3. Rubber cup polishing

  4. Whitening strips

The correct answer is: Rubber cup polishing

Rubber cup polishing is the most common technique for stain removal because it is a gentle yet effective cleaning method. Brushing alone may not be enough to remove tough stains and flossing is primarily used for removing plaque, not stains. Whitening strips may only target surface stains and may not be as effective for deeper stains. While there are other stain removal techniques such as dental bleaching or laser whitening, they are not as commonly used as rubber cup polishing.
