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

- Moderate dark drinks; use a straw when you can.
- Rinse with water after consuming stainers.
- Prefer foods that don't stain after treatment.

## 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.

### Keep your smile white

Book your cleaning or touch-up and keep your result longer.
