Long-term grinding can cause damage to tooth enamel, which can cause symptoms of nerve sensitivity, pain from hot and cold irritation, or substantial defects that can affect a series of physiological activities such as eating, feeding, and drinking. The grinding of the teeth can cause the leakage of the nerve of the teeth, which can cause the inflammation of the pulp, and if it develops downward, it can cause the periapical inflammation of the teeth; or the cyst of the jaw bone of the teeth; or the occurrence of the apical abscess, which can also stimulate the gum of the teeth to produce redness, swelling, recession, and cause the root of the teeth to bifurcate and be exposed, and accompanied by a certain amount of bacterial attachment, causing the resorption of the alveolar bone can cause the loosening of the teeth, and finally the loss of the teeth. The damage to the localized teeth is also caused. The damage to the local teeth will also cause some disorders to the temporomandibular joint or some strains to the joint disc, resulting in disorders of the temporomandibular joint and some joint compulsory symptoms. In the long run, there is a certain damage to bones, teeth and joints, so early intervention and treatment are needed.
