Have you ever wondered what causes black spots on teeth? Black teeth comprises of various external factors, such as enamel damage, coffee stains, and internal factors, such as decay or pulpitis can cause these dark areas. Symptoms often begin with tooth sensitivity and the appearance of small black dots near the gums. Regular dental exams, daily flossing, and brushing with fluoride toothpaste are all part of preventative care, as is abstaining from tobacco and caffeine.
Treatment options range from removing stains and cavities to applying tooth-colored materials or, in severe cases, using weight-bearing dental fillings such as crowns. Long-term dental health depends on consistent oral hygiene and food choices to prevent decay and maintain a bright smile. Let’s get started!
What Are Black Teeth?
Black teeth, also known as black tooth stain or black spot, refers to a dental condition where dark black spots occur on the teeth. This can be a cosmetic dentistry related problem and can indicate more dental problems.
Teeth are made up of three layers:
- Enamel: The tooth's hard outer covering is called the enamel.
- Dentin: Dentin is the layer below the tooth enamel. It contains microscopic tubes that allow heat, cold, and acid to stimulate nerve endings. Damage to the enamel can expose the dentin.
- Pulp: This is the center of the tooth. The dental pulp contains blood vessels, connective tissue, and nerves. Teeth appear black due to enamel discoloration. Teeth can turn black due to external and internal reasons.
External Causes
External causes of tooth darkening come from outside the tooth. These can include:
- Enamel damage
- Stains
- Tartar build-up
Some direct causes of staining include:
- Eating or drinking frequent dark foods such as coffee
- Taking certain medications such as liquid iron preparations
- The use of certain mouthwashes and toothpastes
- The use of tobacco
- Use of crowns and silver sulfide fillings
Internal Causes
A tooth can also be black if the damage is internal. In these cases, the most common causes of black teeth are cavities or dental frameworks. For example, a tooth with pulpitis or a dead tooth may turn black. Damage starts from the inside and spreads to the surface of teeth.
The black color of the tooth may first appear as spots and eventually cover the entire tooth if the person does not seek treatment.
Symptoms
It is unusual for a tooth to change rapidly from white to black. A person usually notices other signs before a tooth turns black. A person’s teeth may become more sensitive, causing pain when eating or drinking, before the teeth become stained.
Small black spots can also appear on the teeth, often near the gums. This is a common phenomenon in children with black teeth. If the cause is tartar, a person will likely notice a black discoloration on the outside of the molars or the inside of the front teeth.
Stain Prevention
Those concerned about the appearance of black teeth should remember to practice proper dental hygiene. This includes:
- Brushing teeth twice a day with flour paste
- Interdental cleaners daily
- Regular dental checkups
People may also benefit from avoiding or reducing:
- Coffee
- Cola
- Black tea
- Red wine
- Tobacco products
Treatment Of Black Teeth
- Treating black spots on the teeth is quite easy, often they can be caused by a small cavity or chip in the tooth, which either takes stains or is slightly rotten.
- A dentist can usually remove a small amount of tooth around this area by removing the stain and/or decay and placing a tooth-colored bonding material in the area.
- Dental bonding naturally blends in with the surrounding teeth, so the repair is not visible.
- Black lines on teeth can be treated with dental bandages as well. If the black line on the tooth is at the gum line and you have a piece of tooth, such as a veneer or crown.
- Whitening of dead teeth is also possible. This is bleaching with a peroxide gel that can significantly whiten teeth.
Sometimes, just teeth whitening is not enough to whiten a dead tooth, and you have to think about some kind of restorative alternative, either a dental filling or a crown.
What Is The Outlook For Black Teeth?
If your dentist can intervene early enough to save the tooth, it is important to maintain good oral hygiene habits to prevent stains, tartar, or cavities from reappearing.
Examples of these habits are:
- Brushing at least twice a day and using fluoride toothpaste
- Flossing or brushing at least once a day
- Regular dental visits as recommended by the dentist (this can take four to six months, some people with severe decay may need to plan more time)
- Eating a healthy diet of fruits, vegetables and whole grains (sugary drinks and foods should be avoided because sugar attracts putrefactive bacteria)
- Avoiding chronic dry mouth, which may be due to the use of certain medications or an underlying condition that causes dry mouth (saliva and moisture wash away harmful bacteria)
- Dry mouth is more likely to decay. With excellent dental care, a person can ideally prevent black teeth from recurring.
Conclusion
A dentist can diagnose blackened teeth due to staining, tartar or decay that require professional intervention regardless of the underlying problem. Effective prevention of blackened teeth requires ongoing dental hygiene such as regular brushing, flossing, and professional cleaning.
After treatment of a blackened tooth oral care can significantly reduce the risk of relapse and ensure long-term dental health.
Frequently Asked Questions
A common misconception is that the tooth darkens after root canal treatment. Teeth often darken before root canal treatment as the tooth rots and decays from the inside. However, a slight darkening of the tooth may occur after the root canal treatment, depending on how the root canal treatment is performed and with which material.
The discoloration may accumulate over years if tooth decay is the root cause. If the stain is caused by trauma, the tissue inside the tooth begins to die and turn black as soon as the blood supply to the tooth is cut off.
If a dead tooth is left untreated, it will turn black as the inner tissue of the tooth dies and decays. If a dead tooth has been root-treated with a tooth-coloring treatment, the tooth may not darken completely, but it may darken slightly.
