What's wrong with the black teeth?

If you don't take good care of your oral hygiene, it will easily lead to many oral diseases, and it will also be detrimental to the health of your teeth and gums. Some people will have black teeth, which will damage the patient's image, easily leave a bad impression on others, and greatly affect normal social interactions. There are many reasons for black teeth, so let's take a look at what causes black teeth.

First, why do teeth turn black? Smoking causes gums to turn black: For some long-term smokers, tobacco pigments will be deposited on the surface of the gums, and the gums will naturally turn black. Drugs cause dark gums: Some drugs that people usually take may change the color of the oral mucosa and teeth. Among them, tetracycline can cause black gums, especially during the growth and development of children. If children take too much tetracycline, their teeth will be constantly stimulated by the drugs, which will cause black spots to appear on the surface of the teeth.

Second, this situation may be caused by periodontitis, or it may be that metal salts are absorbed into the body through the blood circulation, which can form band-shaped or linear light gray or blue-black pigment deposits on the edge of the gums, which are called lead lines or mercury lines.

Third, some people find that their gums are black, unlike other people's gums which are pink, and they worry whether they have some disease. The substances that cause the color change of gums or oral mucosa have two sources. One part comes from the body itself, called endogenous substances, mainly melanin and various pigments from hemoglobin, and the other part comes from outside the body, called exogenous substances, mainly heavy metals, dyes, plant pigments and medicinal properties.

Why do teeth turn black? Tooth decay causes gums to turn black: If there is a problem with oral hygiene and there is too much dental plaque, it will corrode the tissue on the surface of the teeth, forming cavities and causing the gums to turn black. Therefore, you must remember to brush your teeth in the morning and evening to maintain good oral hygiene and prevent tooth decay.
