Why Do Teeth Discolor Over Time?
Tooth discoloration falls into two categories: extrinsic and intrinsic. Extrinsic stains occur on the outer enamel from chromogens in tea, coffee, turmeric, red wine, and smoking. Intrinsic discoloration happens deeper within the dentin due to aging, fluorosis, or childhood antibiotics.
Dangerous Internet DIY Trends to Avoid
Social media is full of dangerous whitening "hacks":
- Lemon or Apple Cider Vinegar: Highly acidic solutions that dissolve calcium from enamel, leaving teeth permanently yellow and sensitive.
- Activated Charcoal Powder: Coarse abrasive particles that act like sandpaper, wearing away enamel and exposing the naturally yellow dentin underneath.
- Baking Soda Scrub: Can remove light surface stains occasionally, but excessive use scratches the smooth enamel surface, making it attract deeper stains faster.
The Safe, Clinically Proven Solution
Professional dental bleaching utilizes pH-buffered hydrogen or carbamide peroxide under gum barrier isolation. The active oxygen molecules break apart stubborn organic stain bonds without altering the tooth mineral matrix. In a single 45-minute clinic session, teeth brighten visibly by several shades with zero enamel damage.
