How long does teeth whitening last?
Professional Philips ZOOM! whitening results typically last 1–3 years, depending on your lifestyle and oral hygiene. Most clients maintain visibly whiter teeth for 12–18 months. Coffee, wine, and smoking accelerate fading. A whitening touch-up every 6–12 months is the most effective way to extend your results indefinitely.
How often should I get a whitening touch-up?
We recommend a touch-up every 6–12 months after your initial full session. If you drink coffee, red wine, or smoke, every 6 months is ideal. Clients with minimal staining habits can stretch to every 12 months. Your dental hygienist will personalize a schedule based on your lifestyle and goals.
Is a whitening touch-up as effective as the first session?
A touch-up is highly effective at restoring and maintaining your initial results. While the full session achieves the initial dramatic transformation (up to 8 shades), the touch-up efficiently removes accumulated surface stains and restores brightness in just 60 minutes. Since it works on a previously whitened base, results are often visibly immediate.
How much does a whitening touch-up cost in Toronto?

Can I get a touch-up if I had my first whitening elsewhere?
Yes. You can book a whitening touch-up at Krystal Dental Hygiene even if your initial whitening was done at another clinic. Our registered dental hygienist will assess your current shade and customize the touch-up to match or enhance your existing results. We use Philips ZOOM! technology for consistent, professional outcomes.
Does coffee ruin teeth whitening?
Coffee does not ruin whitening, but it is the most common cause of post-treatment staining. Dark pigments (chromogens) in coffee gradually deposit on enamel, dimming results over weeks and months. To minimize impact: rinse with water after coffee, use a straw, and schedule touch-ups every 6–12 months. Avoid coffee entirely during the first 48 hours after any whitening session when enamel is most porous.
Can I whiten my teeth before my wedding?
Absolutely. Schedule a full Philips ZOOM! whitening session 2–3 weeks before your wedding, followed by a touch-up 3–5 days before the event if desired. This timeline allows any post-treatment sensitivity to fully subside while ensuring your smile is at peak brightness for photos and the ceremony. Many of our clients specifically book whitening as part of their wedding preparation.
What is the difference between a touch-up and a full whitening session?
A full Philips ZOOM! session takes 120 minutes and costs $450, achieving up to 8 shades whiter — it is the initial comprehensive treatment. A touch-up takes 60 minutes and costs $280, designed to maintain those results. The touch-up uses the same Philips ZOOM! technology but with fewer gel applications, making it a faster and more affordable maintenance option.
How soon after full whitening can I get a touch-up?
We recommend waiting at least 6 months after a full Philips ZOOM! whitening session before getting a touch-up. Most clients maintain good brightness for 6–12 months. If you notice significant staining returning earlier due to heavy coffee, wine, or smoking, consult our dental hygienist — she may recommend a shorter interval based on your individual needs.
Does a whitening touch-up cause sensitivity?
A touch-up may cause mild, temporary sensitivity for 24–48 hours — typically less than the full session since the treatment is shorter. The Philips ZOOM! system uses a pH-balanced gel that minimizes discomfort. Our dental hygienist applies desensitizing agents and customizes the treatment to your comfort. Most clients resume normal activities immediately after their session.
