Tooth decay is not allowed to be brushed off with toothbrush? Tooth decay is usually called worm tooth, but professionally it is called tooth decay. It is a disease caused by bacteria invading the hard tissues of our teeth and causing the decay and disintegration of the hard tissues of the teeth. In order to treat tooth decay, the decayed part of the tooth must be removed by invasive dental turbine drill, and the corresponding cavity shape must be prepared, and the cavity must be filled with special filling material. Brushing mainly plays the role of oral cleaning, prevention of tooth decay and periodontal disease, but it can not cure the tooth decay. For example, tooth decay is equivalent to having a deep cut on our hand. But brushing teeth is only equivalent to washing hands, and when a mouth appears, washing hands certainly cannot solve the problem, and stitches must be applied to make the deeper wound grow better. It is impossible to cure the mouth on the hand by simply washing your hands.
