What Causes Black Teeth?

Tooth discoloration is very common in lots of people and has a bad effect on their quality of life. Once we meet somebody the major thing we notice about them is their smile as well as their teeth. The color of our teeth speaks of the maintenance of our Dental Health. 

First, the color of the teeth gradually turns yellow indicating that our teeth are getting sick. If left untreated, a serious problem occurs. Unluckily, our routine eating habits can become the main cause for causing black teeth. 

Several Facts about Black Teeth 

Black teeth are a serious issue that must be treated instantly. It is an indication of disease under the gums. Calcium is the essential substance that provides color to teeth. The color of the teeth generally varies from whitish gray or whitish yellow. When your teeth start to change color, it is vital to take action and consult your Dentist. 

There is a powerful outer layer named Enamel that protects the gums and roots of the teeth. The enamel layer thins and dentin is exposed as the age grows, making teeth appear darker. 

Black Teeth Cause 

There are two chief reasons why teeth darken: 

  1. Extrinsic

The tooth is damaged owing to exterior factors such as the food we eat, and wrong maintenance of dental health which damages the blackens and enamel of the teeth because of exposure to dentin. 

  1. Intrinsic

Tooth damage begins from inside the teeth roots and shoots out. It isn’t obvious in the first stage. 

Some of the extrinsic and intrinsic factors that impact our teeth are listed below: 

  • Bad oral hygiene is one of the leading causes of the blackening of our teeth. 
  • Consumption of more acidic things such as red wine, tobacco, and brightly colored foods leads to variations in the teeth’ color. 
  • Tartar forms on the teeth which is a thick, hard deposit of plaque, which forms below the gum line. 
  • Part of the tartar is black which blackens our teeth. 
  • Dental restorations, such as crowns and fillings, contain amalgam and silver sulfide that blacken our teeth. 
  • Cavities are formed on the teeth and if left untreated, they leave holes in the teeth that gradually blacken them. 
  • Taking certain medications such as liquid iron supplements causes blackening of our teeth. 

Black Teeth Symptoms 

Black teeth begin as spots on the teeth that initially appear gray or brown. These black spots are generally seen in pinpoint areas below the jawline or on the tops of the teeth. We have to look mainly at the inside of the lower front teeth as well as the outside of the molars because the color originally begins to change from the bottom of the teeth. 

Black Teeth Treatment 

Black teeth are generally treated depending on the diagnosis of the precise reason. If it is caused by a cavity, the Dentist will clean the cavity part and cure the black teeth. Whether holes are created owing to cavities, the doctor will clean and fill them. If cavities have touched the second layer of the teeth, the Dentist eliminates the portion as well as fills it with a crown over the top of the tooth. 

Prevention of Black Teeth 

Black teeth may be avoided with strong dental hygiene. Avoid acidic, sweet, and colored foods, bad habits such as smoking cigars, and tobacco, as well as drinking alcohol. Cleaning your teeth and flossing at least once a day aids in preventing black teeth. 


Black teeth don’t appear all of a sudden so we must be careful and observe the variations that occur in our dental health. Although there is a small alteration in the teeth, act immediately and consult your Dentist and seek his advice.
