Brushing Alone Cleans 70% | Emergency Dental Service Brushing alone can effectively clean around 70% of a tooth's surface, but the remaining 30% must not be overlooked. Remember to add flossing to your dental routine to guarantee complete oral hygiene. Flossing cleans the space between teeth that brushing cannot reach and enhances your overall dental health.
