Why do teeth turn black ?

There are several reasons why teeth may turn black, including:

  1. Decay: When bacteria build up on teeth and form plaque, they can produce acids that erode tooth enamel and lead to cavities. If left untreated, cavities can progress and infect the inner pulp of the tooth, which can cause discoloration and eventually turn the tooth black.
  2. Trauma: Teeth can become discolored or turn black after trauma, such as a blow to the mouth. This can cause damage to the blood vessels in the tooth, which can cause the tooth to die and turn black.
  3. Medications: Some medications, such as certain antibiotics and antihistamines, can cause teeth to become discolored and turn black. This is because these medications can bind to the tooth enamel and cause staining.
  4. Smoking and Tobacco use: Smoking and using tobacco products can cause teeth to become discolored and turn black. The nicotine and tar in tobacco can build up on teeth over time, causing staining and discoloration.
  5. Age: As we age, the enamel on our teeth can wear down, exposing the dentin underneath, which is naturally darker in color. This can cause teeth to appear yellow, brown, or even black over time.

If you are concerned about black teeth or any other dental issues, it’s important to see a dentist as soon as possible for a proper diagnosis and treatment plan.
