Teeth Whitening

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.
