Prevention in dentistry plays a huge role in the prevention of caries, periodontal disease and oral disease. Good hygiene allows you to eliminate odor from the mouth, reduces discoloration and ensures a feeling of freshness. Adhering to its principles allows you to keep a beautiful, healthy smile until old age. The oral examination should take place at least once a year, and in children and people with a high tendency to caries or periodontal disease even every 3-6 months. Lacquering and varnishing of teeth makes them more resistant to caries and less sensitive to thermal stimuli.
