Wisdom teeth become black, considering that may be the emergence of pigmentation, calculus, caries, pulp necrosis and other conditions caused by the need to go to the hospital for different treatments.
1. Hyperpigmentation: Wisdom teeth, also known as the third molar, the teeth of the jaw fossa is deeper, and the position of the wisdom teeth is relatively backward, daily cleaning is more difficult, food or smoking may lead to pigmentation in the fossa of the wisdom teeth, resulting in the wisdom teeth become black, generally can be cleaned up by scaling, sandblasting.
2. Dental calculus: If the wisdom teeth are black in the neck of the teeth, it is possible that poor oral hygiene leads to plaque deposits in the neck of the teeth to form yellowish-brown dental calculus, after a period of time may develop into a black-brown color that makes the wisdom teeth black, you can go to the hospital periodontal scaling to remove the dental calculus.
3. Caries: When wisdom teeth are decayed, the decayed tooth tissues will also be blackened. If the wisdom teeth grow orthodontically and have a good occlusal relationship with the opposing teeth, you can consider using a special turbine handpiece to remove the decayed tooth tissues in time, and then fill the fillings; if the wisdom teeth grow incorrectly, you need to consider extracting them directly.
4. Pulp necrosis: When wisdom tooth caries reaches a certain level, the pulp becomes infected and necrotic, making the wisdom tooth turn dark brown in color, and it is necessary to take a panoramic film to confirm that the wisdom tooth has the value of preservation before root canal treatment; if the wisdom tooth grows at an inclined angle, it is necessary to consider extracting it as soon as possible.
