Does Teeth Whitening Damage Your Enamel?

Professional whitening is safe for enamel

Multiple studies published in peer-reviewed journals confirm that professional-grade whitening products (carbamide peroxide and hydrogen peroxide at dentist-prescribed concentrations) do not cause structural damage to enamel when used as directed.

A 2014 review in the Journal of Dentistry concluded that professional whitening products cause temporary, reversible changes to enamel surface roughness that resolve within 2 weeks of treatment completion.

What CAN damage enamel

• Charcoal toothpaste: The BDA warns that charcoal is abrasive and can wear down enamel with regular use.
• Unregulated whitening products: Products sold online or in beauty salons may contain illegal concentrations of hydrogen peroxide that can cause chemical burns and enamel damage.
• Overuse: Using whitening products more frequently than recommended can cause sensitivity and surface changes. Follow your dentist's instructions.
• DIY remedies: Lemon juice, baking soda scrubs, and apple cider vinegar are acidic and erode enamel. Do not use these on your teeth.

Common side effects (temporary)

• Sensitivity: The most common side effect. Usually mild and resolves within a few days of stopping treatment. Using desensitising toothpaste before and during whitening helps.
• Gum irritation: Can occur if gel contacts the gums. Custom trays (from your dentist) minimise this risk compared to one-size strips.
