Dental shade guide for whitening

Achieving a whiter smile is only half the journey; the other half is keeping it. With simple habits, your result lasts much longer.

The first 48 hours

After whitening, teeth are more prone to pigmentation. Follow the 'white diet': avoid coffee, tea, wine, dark sauces and tobacco for one to two days.

Long-term diet

Hygiene that preserves the shade

Constant brushing, floss and, if your dentist indicates, a maintenance toothpaste help prevent plaque from retaining pigments. Avoid abrasive products that damage enamel.

Touch-ups and cleanings

At-home touch-ups with trays and periodic professional cleanings are the best combination to keep your smile white without repeating the whole process.

Caring for the color is easier than recovering it: consistency is your best ally.

Frequently asked questions

How long should I avoid coffee?

Ideally the first 24-48 hours, when teeth are most prone to pigmentation.

Do whitening toothpastes work?

They help maintain, not deeply whiten. Use them as indicated so as not to damage enamel.

How often do I touch up?

It depends on your habits; many patients do occasional at-home touch-ups to refresh the shade.
