# 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.

## Frequently asked questions

### Does whitening weaken the tooth?

No, if it's professional and well indicated. It acts on the pigments, not the tooth's structure.

### Is the sensitivity permanent?

No, it's usually temporary and managed with desensitizers and treatment adjustments.

### Can I whiten if I have cavities?

Cavities and oral health are treated first; then whitening is done safely.

### Whiten safely

Book your assessment and do your whitening with professional supervision.
