Yes, dead teeth can be yellow, but they can also be gray or black. The discoloration is due to the death of red blood cells within the tooth, similar to bruising. This change in color is a common indicator of a dead tooth, although other symptoms may also be present.
Why Dead Teeth Discolor
The vibrant white color of healthy teeth comes from the dentin and enamel layers, and the inner pulp containing blood vessels and nerves. When a tooth dies, the blood supply is cut off. The resulting lack of oxygen causes the red blood cells to die and degrade, leading to discoloration. This is why a dead tooth might appear yellow, gray, or even black, depending on the extent of the damage and the time elapsed since the death of the pulp.
The discoloration isn't always uniform; it may appear as a gradual shift in color or a localized darkening.
- Yellow: A common initial discoloration, often a subtle change from the surrounding healthy teeth.
- Gray or Black: Indicates more advanced stages of tooth death and decay.
It's important to note that while yellowing is a possible sign of a dead tooth, other factors can also cause teeth to yellow, such as staining from food and drink. Therefore, yellowing alone isn't a definitive diagnosis. A dentist should be consulted for proper diagnosis and treatment.
Treatment Options
Standard teeth whitening treatments are often ineffective on dead teeth because the discoloration stems from within the tooth structure itself. Professional dental interventions may be required, such as internal bleaching or a dental crown. These options aim to restore the tooth's appearance and overall oral health. The approach selected will depend on the specific situation and severity of the discoloration.
