Causes of Tooth Discoloration
Before discussing teeth whitening methods, it’s important to understand the causes of yellowing teeth, which include:
- Smoking:
Tobacco contains substances that stain the teeth, turning them yellow or brown. - Diet:
Consuming foods and drinks like coffee, tea, red wine, and cola can stain teeth due to their natural or artificial coloring agents. - Aging:
Over time, the enamel on the teeth wears down, revealing more of the underlying dentin, which affects the color of the teeth. - Poor Oral Hygiene:
Not brushing teeth regularly leads to plaque and tartar buildup, contributing to tooth discoloration. - Medications:
Some medications, such as antibiotics (especially tetracycline), can cause tooth staining.
