Brush your teeth twice daily: in the morning and before bed. Use a pea-sized amount of fluoride toothpaste. Brush for at least two minutes, covering all surfaces. Use gentle circular motions to avoid gum damage. Complement brushing with daily flossing and rinsing with mouthwash. Avoid brushing immediately after acidic meals; wait 30 minutes to prevent enamel erosion. Regular dental check-ups every six months are essential for maintaining oral health. For optimal stomach health, maintain good oral hygiene to reduce harmful bacteria ingestion.
