A single tooth may appear black due to internal decay.
Understanding Tooth Discoloration
Tooth discoloration can occur for various reasons, but when a tooth turns black, it often indicates a serious issue within the tooth itself. Here's a breakdown of why one tooth might become black:
- Internal Decay: According to the provided reference, a cracked or broken tooth can rot from the inside, leading to a black discoloration. This happens because bacteria can enter the tooth's pulp (the inner part containing nerves and blood vessels), causing decomposition.
The Process of Blackening
- Damage: A crack or break in the tooth creates an entry point for bacteria.
- Infection: Bacteria travel to the pulp and begin to break down the tissues within the tooth.
- Decomposition: This internal decomposition results in the darkening of the tooth from the inside out, which can be observed as a black color.
- Progression: If left untreated, the decay can progress, potentially leading to pain and further complications.
What to do if you have a black tooth?
- Seek Professional Help: A black tooth indicates a serious problem. It should be evaluated by a dentist as soon as possible.
- Root Canal: A root canal may be required to remove the infection and save the tooth.
Common Causes of Tooth Damage
- Trauma (accidents, falls)
- Tooth grinding or clenching (bruxism)
- Large cavities weakening tooth structure
Prevention Tips
- Maintain good oral hygiene by brushing and flossing regularly.
- Attend regular dental checkups for early detection of tooth problems.
- Avoid chewing on hard objects that can crack teeth.
