Are you ready to dazzle the world with a smile that shines brighter than a star?

Have you ever wondered how long teeth whitening lasts after an in-office teeth whitening session?

With an estimated 35 million people expected to use teeth whitening in 2024, in-office whitening is popular.

Let’s journey to uncover the science behind this gleaming transformation.

Welcome to Benca Dentistry, your gateway to a radiant grin in Tukwila, WA.

Say goodbye to lackluster teeth and hello to a smile that lights up the room.

Let’s answer the question, “How long does in-office teeth whitening last?” and the secrets it holds for your lasting confidence.

The science behind in-office teeth whitening: a brief overview

At Benca Dentistry, our experts use advanced techniques to deliver stunning results. 

The process involves a special gel containing whitening agents that penetrate deep into your enamel, breaking down stains and discolorations.

How does in-office teeth whitening work?

Picture this: Your teeth are like a canvas; the whitening gel is the artist’s brush.

The gel works its magic by reacting with the stains, causing them to disintegrate and fade away, revealing the natural brilliance of your teeth.

How long does in-office teeth whitening last?

Ah, the burning question! The duration of your newfound radiance depends on a few key factors:

Lifestyle habits

If you’re a coffee connoisseur or a red wine enthusiast, your teeth might need a touch-up sooner.

These indulgences can gradually tarnish your gleaming grin.

Dental hygiene

The better you care for your teeth, the longer the effects will last. Regular brushing, flossing, and professional cleanings at Benca Dentistry can help maintain your dazzling smile.


Believe it or not, your genes play a role too.

Some people naturally have more resistant enamel, while others might need to visit our Tukwila, WA, practice for a touch-up sooner.
