When thinking about whitening your teeth, the common doubt is whether to do it **in-office** or **at home** with trays. Both work; they differ in speed, control and comfort.

## Comparison

| Criterion | In-office | At home (supervised) |
| --- | --- | --- |
| Speed | High (1-2 sessions) | Gradual (days/weeks) |
| Gel concentration | Higher | Lower |
| Direct supervision | Yes | Dentist's instructions |
| Schedule comfort | Clinic visit | At your home |
| Price | $$ | $ |

## In-office

Ideal if you want **fast results** for an event or simply prefer to resolve it at the clinic. The professional protects your gums and controls the whole process.

## At home

Perfect if you value **comfort** and aren't in a hurry. You use custom trays and indicated gel, with the advantage of maintaining the result over time.

## Which is best?

There's no absolute winner: it depends on your hurry, budget and sensitivity. Many choose a **combined protocol** for the best of both.

> Safety is the same when both methods are indicated and supervised by a professional.

## Frequently asked questions

### Is the at-home one less effective?

No, just more gradual. With consistency it achieves excellent results.

### Can I combine both?

Yes, it's a widely used strategy: a clinic session and at-home maintenance.

### Which causes less sensitivity?

It depends on each person; the professional adjusts concentration and timing to minimize it.

### Choose your whitening
