When choosing a toothbrush, pay attention to the bristle and the toothbrush head’s size. For children or adults who are predisposed to gum irritation or swelling, it is best to choose a soft-bristled and small-head toothbrush. Toothbrushes with medium-to-hard bristles tend to cause damage to the gums, contributing to their recession and irritation. Furthermore, a small-head toothbrush can easily get around hard-to-reach areas of the mouth without irritating and rubbing against the gums. To get a whiter, healthier smile, visit the dentist every six months for dental cleanings.
