What techniques are primarily used for plaque removal?

Brushing, flossing, and coronal polishing are considered the primary techniques for plaque removal because they effectively disrupt and remove dental biofilm, which is the main component of plaque. Brushing serves to physically remove plaque from the tooth surfaces by using a toothbrush and fluoride toothpaste, promoting good oral hygiene. Flossing targets the areas between the teeth where a toothbrush may not reach, helping to eliminate plaque accumulation in those tight spaces. Coronal polishing is a technique that further cleans the tooth surfaces by using a polishing paste to smooth the enamel and remove any remaining plaque and stain, thereby contributing to overall dental health.

The other methods mentioned are less effective as standalone techniques for plaque removal. Rinsing and sucking primarily serve to wash away particles and may not efficiently reduce plaque. Scraping could damage tooth enamel if not done correctly, and while rinsing might help in debris removal, it does not effectively remove plaque. Chewing gum and mouthwash can aid in oral hygiene, but they are not substitutes for the comprehensive plaque removal achieved through brushing and flossing, as they do not physically remove plaque but may help to neutralize acids and freshen breath.
