Oral hygiene refers to the practice of keeping your mouth, teeth, and gums clean and healthy. This is important because good oral hygiene helps prevent problems like cavities, gum disease, and bad breath. Regularly brushing your teeth with a toothbrush and toothpaste and flossing between them can remove food particles and plaque, which is a sticky film of bacteria. In addition to brushing and flossing, visiting a dentist for regular check-ups is essential for maintaining oral health. A dentist can identify any issues early and provide professional cleaning. Drinking plenty of water and eating a balanced diet also contribute to good oral hygiene.
