yellow teeth
Introduction
Introduction Most yellow teeth do not pay attention to oral hygiene, no brushing habits, a layer of food residue, soft dirt, calculus, smoke stains, tea stains, etc. on the surface of the teeth. These "yellow teeth" are not caused by the yellowing of the teeth themselves, but are not caused by oral hygiene. There are also drug factors: such as tetracyclines can cause yellow teeth. The yellowing of the teeth is not necessarily morbid because of the different degrees of calcification in each person's teeth.
Cause
Cause
The latest research found that when the human body is developed, the human body stops supplying auxin to the skeletal system, and the nutritional supply chain of the teeth changes dramatically. At this time, the human teeth will change from the snowy state of childhood to the ivory color (beige) with increasing age. In fact, this is the sign that the life of the skeletal system is gradually becoming inactive.
Perhaps some of the elements in the teeth are also lost, causing a change in color in the nature of the teeth. Many people think that this is only the color change of the tooth surface. It is white when the surface is worn away. In fact, the color and appearance of the tooth are not much different. This is one of the phenomena that affect the teeth after the physiological factors of the human body change. The effects of changes in the physiological factors of the skeletal system on the teeth are the most direct and maximum.
For example, the human body's chronic fluorosis, the main infringement of fluoride is the skeletal system, which can make the body's joints, the spine slowly deformed, but its first symptoms are yellowing, blackening, defect and shedding. For example, in some special areas, people living in this area have a uniform symbol - yellow teeth due to water quality. This is because the skeletal system has been slightly infested and the teeth have a chain reaction. Some of the elements are lost and cause changes in color. If the harmful substances that invade the skeletal system are excluded, or if the physiological state of the skeletal system is completely recovered, then the damage suffered by the teeth can be recovered. The answer is that it can only be repaired, not recovered, just like the tetracycline tooth has become a sequela of life. Therefore, the combination of congenital genetic factors and the comprehensive factors of the period of the period of the gestation period completely determine the morphological nature of the future of the teeth.
Due to genetic factors, the whiteness of the teeth of the yellow people is generally not as good as that of the blacks. The color and shape of the teeth after adulthood are fixed after no significant physiological disturbances (such as tetracycline, high fluoride water, etc.).
The color of the teeth is basically natural, that is, the result of the gene. In the stage of the tooth-care stage, such as before the first tooth, it is especially important to care for the teeth, and the physiological state of the human bone system (such as calcium). Content), also plays an important role in the nature of the teeth (such as the color and shape of the teeth). Therefore, to care for teeth whiter, it is best to start with children.

Diagnosis
Differential diagnosis
Yellowing of teeth needs to be differentiated from the following symptoms
Dark spots of teeth: Some people drink or eat foods that are easy to dye for a long time, or long-term exposure to certain minerals, such as long-term use of potassium permanganate water to gargle, silver nitrate treatment of oral diseases can be exposed to mercury. Both can make the teeth black. Contact with iron, sulfur and other substances, it is easy to make the teeth appear black and green. In addition, enamel hypoplasia, dentin hypoplasia, hereditary opal teeth, dental fluorosis, tetracycline teeth, dental caries, etc. can make the teeth yellow, brown, black.
Green teeth or tan teeth: the sequelae of neonatal bilirubin encephalopathy usually occurs from 2 months to 3 years after birth, hand and foot are moving, eyeball is difficult to turn or strabismus, hearing disorder, enamel hypoplasia with green teeth or brown Brown teeth, the so-called quadruple syndrome, which is mainly caused by damage to the extracorporeal system. In the 835 cases of hemolytic disease in Shanghai, 48 cases of bilirubin encephalopathy were found to be mentally retarded, with convulsions or convulsions, fatigue, and salivation.
The teeth are yellowish light gray or dark gray: the clinical manifestations of tetracycline teeth are yellowish light gray or dark gray. Generally, the anterior teeth are more colored than the posterior teeth than the permanent teeth. In severe cases, there is enamel dysplasia.
