**Teeth whitening** is one of the most requested aesthetic treatments. There are several options and choosing well depends on your goals, your time and your teeth's sensitivity.

## In-office whitening

Performed by the professional with higher-concentration products, sometimes activated with light. It offers **fast, noticeable results** in one or a few sessions, with supervision to care for your gums.

## At-home whitening (supervised)

Custom trays and gel indicated by your dentist are used at home over days or weeks. It's comfortable and effective, though more **gradual**.

## Combined treatment

Many protocols combine an in-office session with at-home maintenance, to achieve a powerful and lasting result.

## What to avoid?

Over-the-counter products or abrasive home remedies can damage the enamel or irritate the gums without good results. Professional whitening is safer and more effective.

> Good whitening doesn't just lighten: it protects your gums and enamel in the process.

## Which to choose?

If you want fast results, in-office; if you prefer to go at your own pace, at-home. The ideal is to define it at an assessment, especially if you have **sensitivity** or visible restorations, which don't change color.

## Frequently asked questions

### Which whitens more?

In-office usually gives faster results; combined offers power and durability.

### Do over-the-counter strips work?

They can lighten a bit, but with less control and more risk of sensitivity or uneven results.

### Do veneers or resins whiten?

No. Restorations don't change color; if you have them, the shade is planned together.

### Brighten your smile safely

Book your assessment and choose the ideal whitening for you.
