If your gums bleed upon brushing, it could be a signal of periodontal disease (gum disease). Don' t mistake it as the gums being hurt by toothbrushing. Although most people brush their teeth daily, it does not mean that the teeth are thoroughly cleaned. If dental plaque accumulates at the gum line (gum margin), the gums would be inflamed. The gums would bleed if the tooth brush bristles touch the inflamed gums. In order to prevent periodontal disease (gum disease), it is important to use proper tooth cleaning methods to thoroughly remove the dental plaque from the teeth. Then, the gums will not bleed and will stay healthy.
