Why Do Teeth Turn Black?
Teeth can turn black due to several reasons, primarily related to decay, trauma, or staining. Let's explore the most common causes:
One of the most frequent reasons for teeth turning black is tooth decay. This occurs when bacteria in the mouth produce acids that erode tooth enamel. As the decay progresses, it creates cavities that can appear as black spots or discoloration. If left untreated, the decay can penetrate deeper into the tooth, leading to more extensive blackening. Poor oral hygiene, characterized by inadequate brushing and flossing, significantly contributes to the buildup of plaque and bacteria, accelerating tooth decay.

Example: If your oral hygiene routine is insufficient to remove acid-producing bacteria daily, the acid gradually dissolves the tooth structure, causing decay that manifests as a black appearance. (Source: The Dental Centre London)
Other Contributing Factors
Beyond decay, several other factors can cause teeth to blacken:
- Trauma: Physical injury to a tooth, such as a fracture or blow to the mouth, can damage the pulp (the inner part of the tooth containing nerves and blood vessels). This damage can lead to discoloration, often appearing as a black or dark gray spot. (Source: Advanced Smile Care)
- Pulp Necrosis: When the pulp dies (a condition called pulp necrosis), it can cause the tooth to turn black. This is often a consequence of severe decay or trauma. (Source: Advanced Smile Care)
- Staining: Certain foods, drinks (like coffee, tea, red wine), and tobacco can stain teeth, sometimes leading to a dark or black appearance. While these stains are often superficial, they can be difficult to remove without professional cleaning. (Source: Medical News Today, My Spearment Dental)
- Medications: Some medications can cause teeth discoloration as a side effect.
Addressing Blackened Teeth
The treatment for black teeth depends entirely on the underlying cause. A dentist can diagnose the issue accurately and recommend the most appropriate solution:
- Professional Cleaning: For stains caused by plaque or tartar buildup, professional cleaning can remove the discoloration. (Source: My Spearment Dental)
- Fillings or Crowns: If the blackening is due to decay, fillings or crowns may be necessary to restore the tooth's structure and appearance.
- Root Canal: If the pulp is affected (e.g., in pulp necrosis), a root canal may be required to remove the infected tissue and prevent further damage.
- Extraction: In severe cases of extensive decay or damage, tooth extraction may be the only option.
Conclusion
It's crucial to address black teeth promptly to prevent further complications and preserve your oral health. Regular dental checkups and good oral hygiene practices are vital for maintaining healthy, white teeth.
