The natural color of teeth can vary from person to person. There is no one “normal” shade of white that an individual’s teeth should be. However, the cumulative effect of many factors can affect the color of the teeth. These factors include diet, aging, tooth decay, tooth trauma and existing dental work.
Stained teeth can be caused by both external and internal factors. The most common causes of stained teeth are:
- Chromogenic foods that have the ability of staining the teeth such as coffee, tea, cola and red wine
- Tobacco including cigarettes, cigars, pipes and even smokeless tobacco
- Certain medications such as tetracycline;
- Tooth decay
- Tooth trauma
- Metal fillings that can show through translucent tooth structure
