We can preserve our beautiful smiles by regularly taking care of our teeth and gums. These should be cleaned using the proper techniques at least twice a day. Choose a toothbrush, toothpaste and floss that bear the approval of your country's Dental Association. Many parents do not understand how important tooth care is for small children, especially infants and toddlers. The truth is that breast milk and formula both contain natural sugars that can attack the enamel on your child's teeth.
