My Crown Fell Off And My Tooth Is Black

Is it normal that my crown fell off and my tooth is black?

It should not be dark. In most cases, tooth discoloration is caused by bacteria invading the crown. In addition, the crown may not be sealed sufficiently. It may be hollow. But in most cases, this is not the case.

Another cause of discoloration is the stain on the fillings of previously restored teeth. No matter what causes the blackening of enamel and discoloration of teeth, you should consult with a dentist as soon as possible. It is especially true if the discoloration comes with pain. Let’s know why the tooth is black beneath a crown.

In this blog, we will discuss the following things:

Why is my crown fell off and my tooth is black?

You have heard people saying, "My crown fell off and my tooth is black." Why is that?

If the teeth under the crown are discolored or blackened, it can indicate a range of dental problems.

It usually means that bacteria have invaded the crown's surface because it is not well sealed or has minor or severe damage that needs to be fixed and repaired as soon as possible.

What can cause a broken tooth to be black or brown inside?

Healthy teeth are not black inside. If my crown fell off and my tooth is black, it may be a sign of internal damage. Following are the possible reasons :

Exposed metal filling

If you notice black spots on your teeth, you may be looking at an old dental filling. Some types of dental fillers, such as mercury and silver amalgam, oxidize and blacken your tooth.

Tooth decay

When bacteria in the mouth swallow the enamel, tooth decay begins. If left untreated, bacteria can damage the inner layer of dentin and cause allergies.

When the injury is close to the pulp, toothache may occur. As tooth decay progresses, toothache continues to worsen. When bacteria completely swallow the dentin, the nerves and blood vessels in the pulp may be damaged and discolored.

You can minimize the risk of tooth decay by:

  • Visiting a dentist regularly
  • Brushing your teeth twice per day
  • Limiting your intake of sugary drinks and foods
  • Flossing at least once per day

Intrinsic stain

Ingestion of dark foods and beverages can cause tooth stains, called exogenous tooth stains. Exogenous dental stains appear on the outer surface of the teeth.

The stain that contains the deep inner layer of the tooth is called endogenous stain. These stains appear when black substances penetrate the teeth. It usually happens during tooth development. Some antibiotics, such as tetracycline, can cause tooth stains in children.

Pulp necrosis

The inflammation of the pulp is called pulpitis. It is usually more sensitive to hot and cold foods and drinks. Pulpitis can occur due to tooth decay or trauma that blocks the blood supply.

Pulp necrosis occurs when pulpitis progresses, and the nerves and blood vessels of the tooth die. With pulp necrosis, the teeth lose the ability to sense heat and cold. The inside of the teeth can also turn black or brown due to the loss of blood supply.

How to Remedy a Discolored Dental Crown?

Specialists can only whiten discolored crowns through dental treatment. This dental treatment is unique to dental crowns. However, you cannot use any whitening products.

Investigate the cause of the discoloration. It is recommended to use a special whitening polish to restore the color of the crown. In this case, dentists will not use whitening strips. The reason for this is that these straps only damage the material of the crown and are susceptible to stain.

Be sure to follow recommended cleaning procedures to prevent discoloration of the crown. Ideally, you should brush your teeth twice a day to minimize the stain on the tooth crown . It also helps prevent plaque buildup.

It is also highly recommended to use dental floss between the crowns. Do this after every meal. It ensures that there are no food particles in between that can cause plaque. You have to lift the particles instead of sliding them over the teeth. It will prevent the crown from slipping.

Sticky foods only adhere to the surface of the crown, so avoid or limit their intake. After eating, be sure to brush your teeth and floss to reduce stains and prevent crown deterioration.

Can I still eat after the dental crown has fallen?

It is best not to eat or drink from the area before the crown is repaired or replaced. The crown is likely to fall out because you were eating too hard, sticky, or crunchy for the tooth to handle.

Moreover, the damaged state of the tooth beneath won't handle that sort of pressure. It may be the reason you had to get the crown in the first place.


My crown fell off and my tooth is black, what should I do? Good oral hygiene is required to prevent the darkening of the teeth under the crown. Remember that your teeth are still perishable. If you don't brush your teeth as recommended, your teeth may rot and turn black.

You should go to the dentist right away. Don't wait until your teeth are badly rotten. If that happens, you will lose it forever.
