If you see black teeth

Does it have to be tooth decay?

 The teeth are actually black

It can be divided into several different situations

Now we will analyze it for you one by one for you

The ① species

The whole tooth surface is dark and heavy

Or appear in a banded dark pattern

This condition is more common in tetracycline teeth

Tetracycline teeth are mainly due to the deposition of tetracycline drugs into the tooth tissue and coloring the teeth.

 But in recent years, with the development of medical level and the popularization of scientific knowledge, pregnant women and infants have little opportunity to access to tetracycline drugs, so the phenomenon of tetracycline teeth has also been reduced.

 species ②

The tooth surface is located close to the gingival area

It ent fine sandblasted brown markings

Such cases are more common in exogenous hyperpigmentation

The pigmentation here is not out in the sun, but we often drink coffee, strong tea and other dark drinks, produce melanin deposited on the surface of the teeth.

 species ③

The teeth are close to the gums

Rough, chocolate-colored patches appear

We need to look at this situation in two ways

If this plaque protrudes from the surface of the tooth, then it is very likely to be a dental calculus. At this time only need to be removed through cleaning teeth.

▼

But if this plaque is below the surface of the teeth, is a concave hole, usually encounter cold and sour will feel sour and soft, it is likely to be a cavity, this situation will need to go to the hospital for filling.

The ④ species

The socket and groove of the molars in the back of the mouth are black

If you see a black line on the groove of the molar at the back of the mouth, you should pay attention to it at this time! Behind the "real culprit" —— dental caries may be slowly developing.

 If not paid attention to, let it develop, it is likely to develop into tooth decay!

 species ⑤

The tooth and the tooth surface adjacent to each other

It was vaguely dark

Medically called it: adjacent surface caries

I don't know if you have noticed when you brush your teeth, we usually only get the three sides of the teeth, the outer side, the inner side and the chewing surface. But the adjacent surface between each tooth can not be brushed.

 You may think that the teeth are next to the brush should not matter, right?

 Then you are very much wrong.

 Bacteria are microorganisms that we can not see with the naked eye, with the distance between the teeth. This is why some friends complain that their teeth are still decayed when they brush them carefully every day.

 So to see that the teeth are black, the situation is very complicated.

 If you can not determine what is caused by the black teeth, it is recommended to the regular oral institutions to check, the doctor will give the corresponding treatment measures according to your personal situation oh!
