Pigmented teeth are yellow or black due to diet, tobacco, tea, coffee, etc., which are attached to the surface of the teeth. Some of them are also caused by eating too many vegetarian drugs when they were young. The teeth are gray, yellow or brown. Another is caused by drinking water with high fluoride content during the calcification period of tooth development. Depending on how affected it is, it can be chalky, tan or dark brown. The color of the teeth is no longer white, and the pigmented teeth are also very worrying.
Dental experts say that there are three specific situations in the formation of pigmented teeth.
1. People who often drink strong tea and smoke, if the surface of the teeth is covered with a layer of pigment, the teeth of tea drinkers are colored yellow-brown, and the teeth of smokers are darker than tea, mostly black, which can make the teeth of the whole mouth clear. The lips, cheeks and tongue are all pigmented.
2. Teeth discoloration caused by tetracycline. Tetracycline teeth often occur in people who have taken tetracycline before the age of 7 due to illness. Because the permanent tooth germ is in the developmental stage, oral tetracycline will stain the hard tissue of the teeth, often manifesting as anterior teeth or full mouth Teeth are discolored.
3. Dental fluorosis, living in areas with high fluoride content in drinking water during the growth and development of teeth, and drinking water with high fluoride content can cause dental fluorosis. It is manifested as chalky or yellowish brown plaques on the surface of the teeth, and in severe cases, there may be tooth defects.
