How long does teeth whitening last?

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.
