This document provides instructions for proper oral hygiene, including brushing teeth, flossing, brushing the tongue, and optional mouth rinsing. It emphasizes the importance of brushing teeth for at least 3 minutes, twice a day using the modified Bass method. Flossing is recommended to remove debris between teeth that brushing cannot reach. Brushing the tongue helps reduce bad breath. Maintaining good oral hygiene through these steps can help prevent dental diseases and issues like bad breath, and promote overall health.
