Basic oral hygiene techniques include brushing, flossing, and rinsing. For brushing, it is recommended to use a soft-bristled toothbrush and fluoride toothpaste. Brushing should be done at least twice a day, ensuring that all surfaces of the teeth are cleaned. Flossing helps remove plaque and food particles from between the teeth and should be done once a day. Rinsing with an antimicrobial mouthwash can help reduce oral bacteria and freshen breath.
