Bright, white teeth are a confidence booster—but if you’re investing in professional whitening, you probably want to know two things: how long does it take and how long will it last?
Here, we’ll explore the answers, plus expert tips and a real patient’s story so you know exactly what to expect before booking your treatment.
How Long Does Whitening Teeth Take?
The length of a professional whitening session depends on the method your cosmetic dentist in Vancouver uses.
| Whitening Method | Time per Session | Number of Sessions | Where Performed |
| In-office laser or LED whitening | 60–90 minutes | 1 session | Dental clinic in Vancouver |
| In-office custom gel trays (high-concentration) | 45–60 minutes | 1–2 sessions | Dental clinic |
| Take-home custom trays (dentist-supervised) | 30 min/day | 10–14 days | At home |
💡 Tip: If you want faster results for a wedding, job interview, or special event, opt for in-office whitening—you’ll see results in just one visit.
How Long Does Professional Teeth Whitening Last?
On average, results from professional teeth whitening in Vancouver can last 6 months to 2 years, depending on your habits, oral hygiene, and the whitening system used.
Factors that affect longevity:
- Diet: Coffee, tea, red wine, and berries can stain teeth faster.
- Smoking: Tobacco is a major cause for discoloration.
- Oral hygiene: Brushing twice daily and flossing extend results.
- Touch-up treatments: Occasional at-home or in-office touch-ups keep teeth bright.
