The baby s teeth are black in every lesson, is it pigmentation?

There will be blackening and defects.

When you encounter yellow, brown, or black teeth, you should first identify the cause of the tooth discoloration. There are two types of tooth discoloration: internal and external.

Intradental staining is tooth discoloration caused by changes in the tooth's tissue structure or nutrition. Common examples include pulp necrosis, plaque enamel tooth and drug deposition causing tooth discoloration.

1. Tooth discoloration caused by pulp necrosis, such as pulp bleeding and necrosis caused by dental trauma, the tooth will turn dark red, brown or blue-gray.

2. Plaque enamel tooth is commonly known as macular tooth, drinking water with a fluoride content of more than 11 million per 1 liter of water before the age of 5 will cause poor calcification and discoloration of the structure of tooth enamel. light plaques with chalky or yellowish-brown patches on the surface of the enamel; The surface of the severe tooth is rough, uneven, yellow-brown, or even black, and the teeth are brittle and fragile, and the tooth is more complex.

3. The mother who causes tooth discoloration caused by the drug is at the end of pregnancy or children under 5 years old, who take more tetracycline and oxytetracycline antibiotics combined with calcium to form yellow or off-white tetracycline, and soil toxin antibiotics combine with calcium to form yellow or off-white tetracycline calcium complex, which is deposited in the structure of tooth enamel and dentin through the pulp, so that the teeth after eruption and early return turn yellow, dark gray or black-brown. The preventive measure is to take as little as possible tetracycline drugs, and at present, pediatric tetracycline drugs have been included in the elimination of drugs.

Extradental staining refers to the pigmentation of the surface of the tooth. For example, smoking, drinking, drinking tea, and the pigments in the diet are mixed with saliva and attached to the surface of the teeth, especially the occlusal surface of the teeth, the grooves of the lips and tongue, and the depression of the fossa are more prone to pigmentation. Stained teeth can be rubbed with a towel or with a cotton swab with 3% hydrogen peroxide.

Severe cases should be removed by a doctor with a rubber wheel to remove the staining.

This is abnormal, which means that the child has tooth decay, which is caused by eating more sugar.

I don't think it's normal, because usually a child's teeth won't be black, and you can see if you're eating anything

If it is abnormal, it means that the child's teeth are not well protected, which will make the child's teeth become particularly black, and parents should help the child clean his teeth in life.

This is very abnormal, it is very likely to be plaque, be sure to take the baby to the hospital for examination, as soon as possible**.
