The Smile You Had 20 Years Ago. Back in 22 Days.
If your natural teeth have yellowed while your implants stayed white, Crest 3D Whitestrips close that gap — no dentist visit required.
We Know the Struggle
You're not alone if you've been avoiding the dentist's whitening chair — or if you're tired of strips that promise results but deliver disappointment.
Expensive Dental Visits
Professional dental whitening costs $500+ in Canada — and requires time off work for an appointment you've been avoiding.
Whitening Strip Skepticism
You've tried whitening strips before, but you're skeptical: will these actually deliver visible results, or is it just marketing hype?
Tooth Sensitivity Fears
You're worried about tooth sensitivity — you've heard horror stories, and you're not sure if the discomfort is worth the reward.
Mismatched Dental Work
Your teeth don't match your dental work anymore: 20 years ago, your implants were colour-matched to professionally whitened teeth, but your natural teeth have yellowed since then.
Slipping Strips
Whitening strips you've used in the past didn't stick properly — they slid around your teeth and left patchy results.

Your Questions, Answered
Crest 3D Whitestrips are Canadian Dental Association validated and use the same enamel-safe whitening ingredient that dentists prescribe. Customer Logan reported visible results within 2 days — well ahead of the 22-day course.
Some users experience mild, temporary sensitivity — it typically fades within an hour and can be managed by applying strips at night or reducing wear time from 45 to 30 minutes. Customer L Platt reports: 'If I used them at night I didn't have any problems with sensitivity.'
At ~$2 per strip, you're getting 22 professional-grade whitening treatments for less than 10% of the cost of a single dental whitening appointment ($500–$800+ in Canada). Many customers wait for Prime Day sales to get an additional 40% off.
Most users report noticeable whitening within 2 days. Full results (20 levels whiter) appear by the end of the 22-day treatment course — though many reviewers confirm visible transformation by the halfway point (11 strips).
Advanced Seal Technology creates a no-slip grip that holds strips firmly in place for the full 45-minute treatment. You can talk, drink water, and move around without strips shifting. Customer Troy M confirms: 'The adhesive was strong and snug against my teeth.'
