2. Custom trays are made from impressions of your teeth, guaranteeing a perfect fit and even coverage.
They typically use 10-30% carbamide peroxide (which is stronger than strips).
But the real advantage isn't just the higher concentration.
Carbamide peroxide releases hydrogen peroxide slowly over 2-8 hours, versus strips that work in 30-60 minutes.
This gradual release causes less tooth sensitivity while delivering longer-lasting results.
Results typically last 6-12 months compared to just weeks with strips.
3. Professional treatments use the highest concentrations:
15-40% hydrogen peroxide.
But they often add heat or light to accelerate the process, delivering results in 1-2 visits.
However, this aggressive approach has two major downsides most people don't consider...
Higher concentrations mean higher sensitivity risk - some people experience pain for DAYS
Plus, despite costing 5-10x more than at-home methods, professional results don't last any longer
You're paying for speed, not better or more permanent results.
But home users, be careful.
Most whitening failures come from user error:
• Applying on stained teeth.
• Overusing products (enamel damage.)
• Skipping the pre-cleaning (uneven results)
• Leaving products on longer than directed (causes sensitivity).
Vanity is an art ↓
Most people achieve 2-8 shades whiter, depending on starting tooth color and stain type.
Heavy coffee drinkers, smokers, and older individuals usually need stronger treatments.
Remember: whitening doesn't work on crowns, fillings, or veneers - only natural tooth enamel.
To maximise your results:
• Get a touch-up every 3-6 months
• Get professional cleanings every 6 months
• Avoid staining foods/drinks for 48 hours after treatment
• Use whitening toothpaste 1-2x per week for maintenance
