What causes your teeth to turn black? Many people’s teeth turn black over time, and a mouth full of black teeth makes people afraid to smile at others, and they become inferior. So why do black teeth appear? What are the causes of black teeth? Next, follow me to find out. There are two main types of tooth blackening, one is endogenous tooth staining and the other is exogenous tooth staining. Endogenous tooth staining is divided into the following 6 categories:
1. Before the teeth erupt: The reasons that affect the embryonic development of teeth and the formation of hard tissue include systemic diseases, such as infant hyperbilirubinemia, blood system diseases, etc.
2. Tetracycline teeth: When teeth develop during mineralization, especially in infants and young children, the use of tetracycline drugs can easily inhibit the mineralization of dental hard tissue. Tetracycline drugs and dental hard tissue form a stable complex, resulting in yellow teeth.
3. Dental fluorosis: This condition is popular and occurs in people in high fluoride areas. When the concentration of fluoride in drinking water or other foods is high, enamel hypoplasia and color changes such as yellow, gray and tan appear on the surface of the teeth.
4. Trauma: due to external force touching the anterior teeth, the pulp is chronically necrotic, and the root canal treatment is not performed in time.
5. Dentin hypercalcification: It may occur after trauma, and the teeth turn yellow or yellow-brown.
6. Carious lesions: The teeth at the carious site turn yellow or black. Exogenous tooth staining is divided into the following 4 categories:
1. Living habits: For example, people who drink tea, smoke or chew palm nut for a long time have brown or black coloration on the surface of their teeth, which cannot be removed by brushing.
2. Poor oral hygiene: Incorrect brushing method, or not brushing your teeth, brushing less, etc., lead to the deposition of plaque and pigment on the surface of the teeth, resulting in the coloring of the teeth.
3. Drugs: Long-term use of chlorhexidine mouthwash may cause brown coloration. 4. Occupational exposure: Exposure to certain minerals, such as iron, sulfur, etc., due to work requirements may cause tooth discoloration.
