Does whitening damage teeth? Myths and facts

Many myths circulate around teeth whitening. Here we separate fact from fiction so you decide with information.

Myth: 'whitening destroys enamel'

False. A professional whitening, properly indicated, doesn't damage enamel. It acts on the pigments, it doesn't 'file down' the tooth. The risk appears with inadequate or misused products.

Fact: 'it can cause temporary sensitivity'

True. It's the most common side effect and is usually temporary. The professional adjusts the concentration and uses desensitizers to minimize it.

Myth: 'it leaves teeth artificially white'

False when done by a professional: a natural, harmonious shade is sought. Exaggerated results usually come from poorly planned expectations or uncontrolled products.

Fact: 'it doesn't work the same on all teeth'

True. Stains from antibiotics, trauma or restorations (resins, veneers) respond differently. That's why a prior assessment is advisable.

Properly indicated and supervised, whitening is safe; the problem is home shortcuts.

The key: professional supervision

The difference between safe and risky whitening is in the diagnosis and supervision. A professional protects your gums, manages sensitivity and seeks a natural result.
