Why do the gaps between teeth and gums turn black?

Dental health is very important to us. Once there is a problem with our teeth, it will not only affect our eating, but sometimes it will also affect our facial shape. There are many kinds of problems that may occur with teeth, so it is important to take good care of your teeth and oral cavity in daily life. Among dental problems, the darkening of the gaps between teeth and gums is a very annoying problem that makes us afraid to open our mouths when speaking. But now more and more people have this problem. Now let’s talk about why the gaps between teeth and gums turn black.

Reason 1

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-like or linear light gray or blue-black pigment deposits on the edge of the gums, which are called lead lines or mercury lines.

Reason 2

There are many factors that can cause gums to turn darker, such as smoking, dentures, pregnancy, endocrine disorders, and vitamin deficiency.

Reason 3

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 substance that causes the color change of the gums or oral mucosa has two sources. One part comes from the body itself, called endogenous substances, mainly melanin and various pigments from hemoglobin. The other part comes from outside the body, called exogenous substances, mainly heavy metals, dyes, plant pigments and medicinal properties.

Suggestions:

1. Clinically, gingival tissue is divided into three parts: free gingiva, attached gingiva and gingival papilla. The attached gingiva of normal people is pink, but in a few normal people, diffuse cloudy melanin deposition can be seen on the surface of the attached gingiva, especially in people with dark skin and blacks. This pigmentation has no pathological significance and does not require treatment.

2. In addition, some exogenous pigment substances, such as heavy metal salts (lead, mercury), are absorbed into the body through the blood circulation and can form band-shaped or linear light gray or blue-black pigment deposits on the edge of the gums, which are called lead lines and mercury lines. In addition, long-term heavy smokers will also have pigmentation caused by tobacco on the surface of the gums. Some drugs can also cause changes in the color of the oral mucosa and teeth.

3. It should be emphasized that if the pigmented areas on the gums or upper palate become rough, raised, bleed easily or develop lumps, you should seek medical attention promptly.
