As brushing? Start with a suitable material, a soft brush filaments that would allow it to reach all the teeth. If the strands of your toothbrush are bent or worn, buy another. A brush in poor condition, does not adequately clean their teeth. To clean the external surfaces of the teeth, place the brush at a 45 degree angle supported by the union of the gum and tooth. Gently move the brush several times using small circular movements and/or side.
