Professional whitening is one of the most requested cosmetic treatments, and the most common question about it is whether it harms the teeth.

Is it safe for enamel?

When it is supervised by a dentist and used on healthy teeth, whitening gel lightens the stains inside the tooth without wearing the enamel away. Problems come mostly from overuse or unsupervised products.

Why do teeth feel sensitive?

Temporary sensitivity during or after whitening is common. It usually settles within a few days, and a desensitising gel or toothpaste helps.

Who should not whiten yet?

Teeth with untreated cavities or gum problems should be treated first. Crowns, veneers and fillings do not whiten, so they may need replacing afterwards to match.

How to keep the result

Limit coffee, tea and smoking, rinse after dark drinks, keep regular cleanings, and use touch-up sessions or trays when your dentist advises.

A short check before whitening makes sure it is safe for your teeth and tells you what result to expect.
