Why Do Teeth Become Discolored?
Tooth discoloration occurs when stains accumulate on or within the tooth structure. While daily brushing removes surface debris, deeper stains often require professional whitening.
- Extrinsic stains: Coffee, tea, red wine, tobacco
- Intrinsic stains: Aging, trauma, medications
- Natural aging: Thinning enamel reveals darker dentin
How Does Teeth Whitening Work?
Whitening treatments use peroxide-based agents that penetrate enamel and break down stain molecules into smaller, colorless fragments—making teeth appear brighter without damaging tooth structure.

Professional Whitening Options
- In-Office Whitening: Immediate results using high-concentration gel under professional supervision
- Take-Home Kits: Custom trays with controlled whitening over 1–2 weeks
- Combination Therapy: Best for long-lasting brightness
Over-the-counter products may provide mild improvement but lack the strength, customization, and safety of professional treatments.
Sensitivity, Safety & Expectations
Temporary sensitivity is common and usually resolves within 24–48 hours. Whitening does not damage enamel when performed correctly.
- Results vary based on tooth structure and stain type
- Fillings, crowns, and veneers do not whiten
- Maintenance may be needed every 6–18 months
