Habit to break: Brushing too hard
Using a firm-bristled toothbrush and too much pressure to clean teeth can permanently wear away protective enamel (triggering tooth sensitivity and cavities) and cause receding gums. Instead, use a soft brush and gentle, circular scrubbing motions for two minutes at least twice a day. When buying a toothbrush, consider that compact heads move most easily around small mouths and long, flexible handles are best for reaching back molars.
