What to do if there is black stain on the teeth

1. Brushing your teeth in the morning and evening and rinsing your mouth after meals are simple and effective ways to prevent the formation of dental tartar. When dental tartar first forms, it is easy to remove it using oral cleaning or brushing. However, it is difficult to remove when the deposits become thicker, calcified, and tightly attached. 2. Dietary structure: Thorough chewing of crude fiber foods rich in vitamins is beneficial to the cleaning of the tooth surface. Fine cakes, sweets, and sticky snacks are easily deposited on the tooth surface and easily form tartar. You must brush your teeth and rinse your mouth in time after eating such foods.

1. Add some milk to coffee. For girls who like to drink coffee or tea, adding a little milk to the drinks can effectively change the chemical structure of coffee, tea and other drinks, making it difficult for pigments to adhere to the surface of teeth and preventing teeth from turning black and yellow. If you think the taste is unpleasant, use a straw to help you drink it, and try to minimize the amount of pigment attached to your teeth. 2. Eat more dark green vegetables. Eat more dark green vegetables, such as spinach, broccoli, etc. These are rich in minerals and can form a protective film on the surface of teeth to prevent tooth discoloration. You should also eat more apples, pears, celery and carrots. Chewing can promote saliva secretion, reduce oral bacteria and whiten teeth.

Why do teeth turn black?

1. Reasons for the darkening of the outer surface of teeth: Bad living habits. Long-term habitual drinking of dark foods such as coffee, strong tea, cola, etc. will cause teeth to turn yellow and black. Other bad habits such as smoking and chewing betel nuts can also cause dark pigments to accumulate on the surface of teeth and even penetrate into the tooth enamel, causing discoloration. 2. Reasons for darkening of the inside of teeth: The most common drug causing tooth discoloration is tetracycline antibiotics. These drugs can affect tooth tissue during the calcification process of tooth development and cause permanent discoloration. Anyone from a fetus in the womb to an 8-year-old schoolchild can be affected by this drug. In mild cases, part of the teeth will turn yellow and gray, while in severe cases, the entire teeth will turn black. The degree of discoloration depends on the amount of the drug taken and the length of time it is taken. In addition, semi-synthetic tetracycline, which is often used to treat severe acne, can also cause discoloration after tooth formation and development are completed in adolescents or adults, so be careful. Excessive intake of other substances such as fluoride can also cause tooth discoloration.
