# Why are my teeth yellow despite brushing?
*Quick Dental Answer | 2026-05-26*
## The Short Answer
> **Yellowing can be intrinsic (inside the tooth) or extrinsic (surface stains). Aging naturally thins the white enamel, revealing the yellow dentin underneath. **Coffee, tea, and turmeric** also stain the surface. Brushing alone cannot whiten deep stains.**
## Clinical Explanation
For surface stains, a professional cleaning works. For deeper yellowing, "Professional Zoom Whitening" is required to bleach the enamel safely. Avoid abrasive "whitening toothpastes" as they damage enamel over time.
