Whiter teeth
Most everyday discoloration is extrinsic: pigment that sits on the outside of enamel from coffee, tea, red wine, and tobacco. It responds well to gentle daily polishing agents and low-concentration peroxide. Intrinsic staining — inside the tooth from age, trauma, or certain medications — needs a dentist's help.
Signs to look for
- Yellow or grey cast across all teeth
- Darker lines near the gumline or between teeth
- Teeth that look duller in photographs than in the mirror
Common causes
- Tannins from coffee, tea, and red wine
- Tobacco and vaping residue
- Enamel thinning with age, revealing yellow dentin
- Plaque buildup that traps pigment
What actually works.
Polish daily, not aggressively
A whitening paste with hydrated silica or activated charcoal lifts surface stain. Abrasive scrubbing does not speed it up — it thins enamel.
Add peroxide 2–3x a week
A low-concentration strip or gel handles deeper stain. Alternate days if you feel any zing.
Rinse after staining drinks
Water immediately after coffee removes most pigment before it sets. Wait 30 minutes before brushing.

Common questions
How fast will I see results?+
Surface stain usually lifts in 1–2 weeks of daily use. Peroxide whitening shows in 3–7 days.
Does charcoal actually whiten?+
It polishes off surface stain effectively, but it does not bleach. Look for a fine, low-abrasion formula.
