Proper oral hygiene is the foundation of healthy teeth and gums, as well as the prevention of many diseases. Properly organized care includes daily brushing of teeth twice a day with a brush of suitable hardness, using dental floss to remove food debris between the teeth and mouthwash to freshen breath. However, even the most thorough home care is no substitute for professional cleaning at the dentist, which is recommended every 6 months. This helps remove tartar and plaque that cannot be removed independently. Doctors also select care products suitable for each patient, including special pastes for sensitive teeth, rinses with antiseptics and irrigators. The correct technique of brushing teeth is of great importance – improper use of a brush can damage the enamel and gums. Experts give advice on nutrition, since excess sugar and acidic foods can cause caries and enamel erosion. Oral care begins in childhood, so it is important for parents to instill healthy habits in children and regularly visit the dentist for prevention. A healthy smile is not only aesthetic, but also an indicator of the overall health of the body.
