Black teeth may be caused by caries, pigmentation and other reasons.
1. Caries: If the patient has caries on the surface and neck of the teeth, the surface of the teeth may be black. Caries and demineralization may also occur if the patient does not maintain good oral hygiene habits during orthodontic treatment. In the early stages of demineralization, irregularly shaped chalky spots appear on the surface of the teeth, i.e., early caries in the enamel. When the degree of demineralization is severe, the enamel surface will fall off and obvious caries will appear and the teeth will turn black.
2. Pigmentation: Patients who drink tea, coffee, chocolate for a long time, smoke for a long time and are exposed to related substances at work for a long time may darken their teeth, which in most cases will not damage the teeth themselves. Generally through methods such as scaling helps to eliminate the black color.
There are many other reasons for blackened teeth, and patients are advised to seek prompt medical attention to clarify the cause of the problem and then carry out the relevant treatment.
