In-office teeth whitening procedure

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.

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.
