Flossing is the best way to clean between teeth and disrupt the food and plaque build-up. Follow through by using a soft bristled toothbrush angled at a 45 degree to the gum line with small circular motion.
Rinse with water and consider using a fluoride rinse if moderate to high caries risk or recommended periodontal rinse. Brushing your teeth at least twice a day, especially at night, is the best way to keep your teeth healthy for a lifetime.
