What is the reason for the black teeth

In daily life, we often encounter various dental problems, such as blackening of the teeth or yellowing of the teeth. There are many reasons for this situation, the most likely one is that it has a lot to do with our eating habits. The food we eat contains various pigments, and pigment deposition will cause the teeth to become black. Or it could be the influence of the environment. When people consume too much fluoride, it can also cause the gaps between teeth to turn black.

Reason 1: Why do the gaps between teeth turn black? Pigment deposition. Most of the foods we eat every day contain pigments, especially coffee, tea, soy sauce, etc. The longer you eat them, the more pigments in them will be deposited on your teeth, causing them to turn yellow or even black. The most important thing to note is that this staining is generally permanent, and even with teeth cleaning or bleaching solutions it is difficult to restore the original color of the teeth. Tips: Thoroughly chewing crude fiber foods containing vitamins is beneficial to the cleaning of the tooth surface. Fine cakes, sweets, and sticky snacks are easily deposited on the tooth surface and easily form tartar. You must brush your teeth and rinse your mouth in time after eating such foods.

Reason 2: Why do the gaps between teeth turn black? It’s dental calculus caused by dental plaque. Dental plaque is a soft deposit formed by bacteria in the mouth, such as Lactobacillus and Streptococcus mutans, combined with a sticky matrix. It is firmly attached to the tooth surface, just like moss growing on moist ground. Over time, the gaps between teeth gradually turn black. Tartar attached to teeth affects the appearance and the restoration effect of dentures. Removable dentures (also known as removable dentures) with tartar will fit tightly with the tooth surface, easily leading to the accumulation of food debris on the dentures and causing oral inflammation. Tips: When dental plaque is in the mild stage and turns yellow, it is slowly forming. At this time, we can hold white vinegar in our mouth for 3-5 minutes, letting the vinegar wash back and forth in our mouth. Then scrub with a toothbrush dipped in salt water.

Reason three: What causes the gaps between teeth to turn black? Tooth decay. Dental caries is an important cause of darkening of teeth, which is manifested by the corrosion, softening and discoloration of tooth enamel, which gradually develops into defects in tooth hard tissue and the formation of caries. Nowadays, many people only brush their teeth perfunctorily and do not pay attention to oral hygiene at all. This leads to the growth of oral bacteria, dental plaque eroding the teeth, forming cavities and causing the teeth to turn black. Tip: The main method of treating caries is filling. The carious tissue is removed completely, a certain hole shape is made, and after cleaning and disinfection, it is filled with filling materials and the shape of the tooth defect is restored so that the aging process will not continue to develop.

Reason 4: Why do the gaps between teeth turn black? Excessive fluoride intake. In many cases, if patients drink water with a high fluoride content, their teeth will become mineralized and gray in color, forming the so-called fluorosis. Some patients with severe fluorosis have underdeveloped and uneven teeth. Tips: The most ideal prevention method is to choose a new water source with appropriate fluoride content, especially during the period of children's tooth development. Activated alum or activated bone charcoal can also be used to remove excess fluoride in the water source, but the latter is expensive and difficult to promote.
