Teeth whitening before and after results often surprise patients with how dramatically their smiles can improve. Whether it's in-chair laser whitening or professional-grade take-home kits, most patients notice a difference of several shades after just one treatment.
In this blog, we'll walk you through what results to expect, the factors that influence your outcome, real examples, and tips to maintain your brighter smile.
What Do Teeth Whitening Before and After Results Look Like?
Patients can typically expect their teeth to lighten by 5 to 8 shades after professional treatment.
Common outcomes by method:
-
Zoom Whitening Before After: Up to 8 shades whiter in just one appointment
-
In-Chair Whitening: Fast and immediate results using clinical-strength peroxide
-
Take-Home Whitening Kits: Gradual brightening over 7 to 14 days
Actual results vary depending on your original tooth colour, lifestyle habits, and enamel condition.
What Factors Influence Your Whitening Results?
| Factor | Impact |
| Natural Tooth Colour | Yellow shades whiten more easily than grey tones |
| Type of Staining | Surface stains (from coffee, wine, tobacco) respond better than deep intrinsic stains |
| Whitening Method | In-office treatments are stronger and more controlled |
| Lifestyle Habits | Smoking and staining foods can darken teeth again quickly |
| Oral Hygiene | Daily brushing, flossing and regular dental cleans help maintain brightness |
