Erosions are one of the more common oral occupational diseases among workers who produce and use acids, with common clinical manifestations including tooth fracture and enamel loss. Dental erosion is caused by longer exposure to various acid mist or acid anhydride leading to decalcification defects in the hard tissues of the teeth, mainly manifested as tooth surface depression, rupture, loss of tooth enamel, and in severe cases, it will lead to brittle surface of the teeth, chipping, falling off, and even fracture of the teeth. It also causes symptoms such as food blockage, sensitivity to hot and cold stimuli, pain, bleeding gums, and weakness in chewing. As the disease progresses, it may even affect the whole body and cause inflammation of the respiratory or digestive tract. Usually, you should pay attention to protect your teeth, do not eat irritating foods, and do not come into contact with chemicals. If you have symptoms, seek medical attention promptly.
