The result of **teeth whitening** isn't permanent, but it can last quite a while if you care for your habits. Here's what to expect and how to extend it.

## Typical duration

In general, whitening lasts between **several months and a couple of years**, depending on your diet, hygiene and habits like smoking. With maintenance, it lasts considerably longer.

## What wears down the result

- **Staining drinks and foods**: coffee, tea, red wine, cola sodas.
- **Tobacco**: one of the strongest causes of re-pigmentation.
- **Poor hygiene**: plaque retains pigments.

## How to keep it longer

- Reduce staining foods and drinks, or use a straw.
- Brush after consuming them when you can.
- Attend your dental cleanings.
- Do **touch-ups** with at-home trays when your dentist indicates.

> Whitening is maintained with habits, not just the initial treatment.

## Maintenance touch-ups

If you got custom trays, you can do **occasional touch-ups** at home to refresh the shade, without repeating the whole process. It's the most practical way to keep your smile white.
