You should brush your teeth at least twice daily, once in the morning and once before bed, for about 2 minutes each time. Hold your toothbrush at a 45-degree angle to your gums and use gentle, circular motions to ensure all surfaces are thoroughly cleaned. Do not forget to brush your tongue. Floss daily to clean between teeth where your brush cannot reach. Use a soft-bristle toothbrush and replace it every 3-4 months. Consult a dentist regularly for check-ups or if you notice any dental issues, such as bleeding gums, tooth pain, or cavities.
