Brush your teeth after every meal.

Use an electric ultrasonic toothbrush, preferably with medium bristles. Replace it every 6 to 8 weeks.

Clean the interdental spaces once a day with interdental brushes.

Use toothpaste with a high fluirin content (+ than 0,15%) but with little abrasive (RDA abrasivity below 80).

If you have taken acidic food (apple, ornament, etc.), wait 30min before brushing your teeth.
