Can Whitening Damage Your Teeth?
Bright, white teeth are a confidence booster—but many worry that whitening might weaken their enamel. At Dentist‑Acton, we believe in evidence-based cosmetic dentistry: when done professionally, teeth whitening is safe and effective, with no enamel damage.
Myth: Whitening Wrecks Your Enamel
Many patients think that any hydrogen peroxide bleach will strip their enamel. In reality, professional whitening uses carefully controlled concentrations and techniques that avoid permanent damage. While low‑quality over‑the‑counter kits (or DIY hacks!) can harm enamel, licensed professionals ensure safety.
The Science Behind It
-
A recent European expert review confirmed that hydrogen peroxide penetrates enamel safely, without long-term harm .
-
Though laboratory studies show mild, short‑term microhardness changes, saliva and fluoride naturally re-mineralise enamel quickly.
When DIY Kits Go Wrong
Unregulated whitening kits—especially those with >33% hydrogen peroxide—can cause:
-
Enamel erosion or surface roughness
-
Gum burns or nerve irritation
Some toothpastes with harsh abrasives (like charcoal) can worsen enamel wear.
Why Professional Whitening Is Safe
-
Custom Treatment Plans
We assess you for enamel thickness, gum health, restorations, and sensitivity before recommending whitening. -
Dentist-Supervised Use of Peroxides
Higher strength peroxide gels (6‑10%) are carefully managed to minimise risk. -
Protective Measures
Rubber dams or gingival shields protect soft tissues; light-activated systems shorten exposure time . -
Post‑Whitening Care
Enamel re‑mineralises naturally—fluoride rinses, desensitising toothpaste, and avoiding staining foods help results last.
Temporary Sensitivity ≠ Damage
After whitening, up to 78% of patients report temporary sensitivity. Symptoms like zingers or gum irritation are usually mild and fade within days. If needed, we offer immediate relief solutions—potassium nitrate gel, desensitising paste, even short course painkillers.
Long-Term Whitening Safety
-
Safe frequency: no more than 2 professional sessions a year to avoid over-whitening and enamel dehydration.
-
At-home maintenance: gentle enamel‑safe trays and gels. Professional guidance ensures you avoid overuse.
