Can a black tooth turn white again?

Causes of a Black Tooth

There are several factors that can contribute to a tooth turning black. One common cause is dental decay, also known as a cavity. When a cavity is left untreated, it can progress to the point where the tooth becomes black due to the breakdown of the inner layers.

In some cases, trauma to the tooth can also lead to discoloration. This can occur from a fall, accident, or even a sports-related injury. When the tooth experiences trauma, the blood vessels inside can rupture, causing the tooth to turn black.

Treatments for Turning a Black Tooth White

Fortunately, there are treatments available that can help turn a black tooth white again. The specific treatment option will depend on the underlying cause of the discoloration.

If the black tooth is due to dental decay, the first step is to remove the decayed area and fill the cavity with a tooth-colored filling material. This will help restore the tooth's appearance and prevent further decay.

In cases where trauma has led to a black tooth, a root canal procedure may be necessary. This involves removing the damaged pulp inside the tooth and replacing it with a filling material. Once the root canal is complete, a crown or veneer can be placed over the tooth to restore its natural color.

Prevention is Key

While treatment options exist for turning a black tooth white, it's essential to focus on prevention to maintain a bright and healthy smile. Regular brushing and flossing, along with routine dental check-ups, can help prevent tooth decay and reduce the risk of a black tooth.

Additionally, wearing a mouthguard during sports activities can protect against traumatic injuries to the teeth. Taking these precautions can go a long way in preventing the need for complex treatments down the line.


A black tooth can be a cause for concern, but it is not necessarily a permanent problem. With the right treatment and preventive measures, it is possible to turn a black tooth white again. Consulting with a dentist is crucial to determine the underlying cause and develop an appropriate treatment plan. Remember, maintaining good dental hygiene is key to preventing dental issues and preserving a bright and healthy smile.
