1. Why teeth discolor over time
Even the brightest smile can dull with time. Everyday life — from coffee to aging — leaves behind pigments that penetrate enamel.
Teeth discoloration falls into two main categories:
| Type | Where It Happens | Common Causes |
|---|---|---|
| Extrinsic stains | On the outer surface (enamel) | Coffee, tea, red wine, tobacco, dark sauces, berries, poor oral hygiene |
| Intrinsic stains | Beneath the enamel surface | Aging, medications, trauma, excess fluoride, genetics, enamel thinning |
Both affect how light reflects off your teeth — but only some respond to whitening.
2. Stains that respond best to whitening
The good news: most everyday discoloration — what dentists call extrinsic stains — can be removed with peroxide-based whitening gels like those used in Expertwhite systems.
✅ Responds well to whitening:
-
Coffee, tea, and red wine stains
-
Tobacco and nicotine discoloration
-
Yellowing from aging or enamel wear
-
Food pigments (berries, curry, sauces)
-
General dullness from plaque or buildup
These are oxidized away by peroxide releasing oxygen molecules that break the chemical bonds in stain pigments.
3. Stains that whitening can improve but not erase
Some deeper or internal discolorations may lighten slightly but won’t fully disappear:
⚠️ Partially responsive stains:
-
Grayish tones from aging dentin
-
Tetracycline or medication stains
-
Fluorosis (white or brown mottling)
-
Trauma-related discoloration
-
Thin enamel showing darker dentin beneath
Even in these cases, whitening helps by removing surface pigments and brightening the overall shade — often giving the smile a visibly fresher look even if deep discoloration remains.
4. When whitening doesn’t change color
Whitening gel cannot alter the color of artificial materials such as:
-
Crowns
-
Veneers
-
Fillings or bonding composites
-
Implants
However, whitening your surrounding natural teeth with Expertwhite can create a cleaner, more balanced overall shade.
If you plan to update restorations, it’s best to whiten first — then color-match new dental work to your brighter natural enamel.
5. The science behind whitening — why peroxide works
Professional whitening relies on carbamide peroxide or hydrogen peroxide. Both release oxygen molecules that diffuse through enamel to break down deep stains.
-
Hydrogen Peroxide: Fast-acting, great for short treatments (like prefilled trays or LED kits).
-
Carbamide Peroxide: Slower-release, gentler option perfect for home trays and overnight wear.
Expertwhite’s 35% Carbamide Peroxide Gel combines both power and control — whitening up to 10 shades in 5–7 days without sensitivity.

8. Final verdict: what whitening can (and can’t) fix
✅ Can whiten: surface stains, yellowing, tobacco, coffee, tea, wine, and mild intrinsic discoloration.
⚠️ Can improve: deeper intrinsic stains (age, medication).
❌ Cannot change: crowns, veneers, fillings, or implants.
