Why are my teeth yellow despite brushing? | Dentist Answer

# Why are my teeth yellow despite brushing? *Quick Dental Answer | 2026-02-25* ## 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. ## Related Treatments * [Teeth Whitening](/treatments/teeth-whitening) * Veneers ## When to see a doctor?
