“Laughing is a physical exercise of great health value.” (Aristotle) A natural, friendly smile is inviting and exudes pure joie de vivre. Well-groomed and healthy teeth are essential for a friendly smile. Beautiful, healthy teeth are largely a question of oral hygiene, regular dental check-ups and dietary habits. Oral and dental health is often interrelated with the health of the entire body. Regular brushing is necessary to maintain oral health in the long term, but not always sufficient. This is because the teeth make up only about 25% of the mouth. No matter how well the teeth are mechanically cleaned, you can't remove all bacteria in the entire oral cavity with a toothbrush, because bacteria are everywhere in the mouth — they can be found on the tongue, on the gums and even on the palate.
