Proper brushing at least twice a day, in combination with the use of a mouthwash, is the first step to ensure healthy teeth and gums. It takes at least 2 minutes of brushing for the effective removal of plaque. To prevent damaging tooth enamel and irritating the gums, use a toothbrush with soft or medium bristles and replace it every 2-3 months. Squeeze required amount of toothpaste onto a brush with soft to medium bristles and brush for at least two minutes. Rinse.
