The ADA recommends the following for for good oral hygiene:

• Brush your teeth twice a day with an ADA-accepted fluoride toothpaste.
• Clean between your teeth daily with floss or interdental cleaner. Flossing  removes  plaque and food particles from between the teeth and under the gum line.
  
• Eat a balanced diet and limit between-meal snacks.
• Visit your dentist regularly for professional cleanings and oral exams.
