Children's teeth turn black

Children love to eat sweets very much. If you don’t pay attention to hygiene under such circumstances, some problems will arise. The most common one is blackening of teeth, which means that cavities have appeared in your child’s teeth. If you don’t control it in time, the condition will only become more serious, and eventually lead to loose teeth or easy damage.

Black spots on children's teeth

1. Tooth discoloration caused by pulp necrosis. If the teeth are traumatized and the pulp becomes bleeding or necrotic, the teeth will turn dark red, brown or blue-gray.

2. Mottled enamel is commonly known as yellow teeth. If you drink water with a fluoride content of more than 1/1,000,000 per liter before the age of 5, the enamel structure will become poorly calcified and discolored. In mild cases of mottled tooth enamel, there are chalky or yellow-brown patches on the enamel surface; in severe cases, the tooth surface is rough, uneven, yellow-brown, or even black, the teeth are brittle and fragile, and treatment is more complicated. For mild enamel stains, dentists can use dilute hydrochloric acid to rub the yellow area to depigment it, which can make the yellow spot lighter, but when applying the medicine, you must pay attention to protecting the gums to prevent corrosion and burns. Severely mottled teeth can be restored to their original appearance and beauty using "plastic veneers" or "light-cured composite resins."

3. Tooth discoloration caused by drugs. Mothers in late pregnancy or children under 5 years old take more tetracycline and oxytetracycline antibiotics, which combine with calcium to form yellow or grayish white tetracycline and oxytetracycline-calcium complexes. These complexes are deposited in the structure of the enamel and dentin through the dental pulp, causing the erupted teeth to turn yellow, dark gray or dark brown. The preventive measure is to take tetracycline drugs as little as possible. Currently, tetracycline drugs for children have been listed as obsolete drugs.

Solution: Brush your teeth more often and eat more fruits rich in vitamins

Calcium deficiency in infants and young children makes their tooth enamel rough and uneven, making it easy for food debris to remain. If the lactobacillus in the mouth attaches to the enamel surface to form plaque, the bacteria in the plaque will continuously decompose food and produce a large amount of organic acid, which will corrode the teeth with underdeveloped enamel. The color of the teeth will gradually change from white to black and fall off little by little.
