1, tooth decay
Tooth decay begins to turn black from the inside of the tooth. Because the inside of the tooth has been corroded, it will turn black bit by bit and eventually become unusable. In addition, unnatural teeth with fillings or other related treatments will gradually become old and necrotic over time, so they will also turn black. This kind of tooth decay or black teeth caused by filling teeth needs to be treated and remedied in a regular stomatological hospital. After that, we should maintain oral hygiene, reduce sugar and prevent tooth decay.
2, tetracycline teeth
There is also an internal cause of tooth blackening, which is caused by tetracycline antibiotics. This is permanent discoloration. The more you take this medicine, the longer it lasts, and the darker your teeth will be. This blackening is caused by the calcification of the internal tissues of your teeth, which cannot be recovered in the later stage. Therefore, its treatment can only be to stop using such drugs to slowly control its deterioration, and try not to ingest foods containing fluorine, which is a substance.
3. Bad habits
Drinking dark drinks such as coffee, strong tea and cola for a long time, or smoking and chewing betel nut for a long time will cause pigmentation on the outside of teeth, make a layer of black substance attached to the surface of teeth, and even go deep into tooth enamel, causing internal discoloration. Therefore, get rid of these bad habits immediately, drink plenty of water, brush your teeth once in the morning and evening, brush your teeth carefully and rinse your mouth with water after meals, maintain oral hygiene, and stick to it, and your teeth will gradually return to whiteness. In addition, you can go to a regular hospital for ultrasonic tooth cleaning, which can immediately restore whiteness. Pay attention to removing bad habits in the future to keep your teeth clean and white. The disadvantage is that tooth washing may cause some harm to teeth and gums, so you can only wash your teeth once a year at most.
4. Aging
Finally, the question of age. With the growth of age, teeth will age, enamel will become thinner, and it will become more and more yellow and darker. This is a necessary process for everyone. Even teeth will naturally fall off when they are old. Therefore, we should pay attention to protecting our teeth from childhood, paying attention to cleaning and oral hygiene, and brushing our teeth every morning and evening, so that we won't be so dark or even lose our teeth when we get old.
