Are Teeth Whitening Trays or Gels More Effective?
Short answer–it depends. Whitening trays are custom-fitted or one-size-fits-all moulds that hold whitening gel against your teeth. The gel contains hydrogen peroxide or carbamide peroxide that actually whitens your teeth. Essentially, trays are the delivery system, while gels are the whitening agent.

Are professional whitening trays better than over-the-counter options?
Yes, professional custom-fitted whitening trays from a dentist are significantly more effective than over-the-counter options. Clinical studies show custom trays achieve 43% better whitening results compared to stock trays using identical gel concentrations. Custom trays fit precisely to your teeth, ensuring even coverage and preventing gel leakage.
How do different whitening methods compare?
| Method | Effectiveness | Speed | Convenience |
|---|---|---|---|
| Custom Trays | ★★★★★ | ★★★★☆ | ★★★★☆ |
| Stock Trays | ★★★☆☆ | ★★★☆☆ | ★★★★☆ |
| Whitening Strips | ★★★☆☆ | ★★☆☆☆ | ★★★★★ |
| In-Office Treatment | ★★★★★ | ★★★★★ | ★★☆☆☆ |
| Whitening Toothpaste | ★★☆☆☆ | ★☆☆☆☆ | ★★★★★ |
Custom trays provide the best balance of effectiveness and convenience, while in-office treatments offer the fastest results.
What are the cost considerations for different whitening options?
- Professional Custom Trays: £250-£400 initially, with refill gels costing £20-£50
- Over-the-Counter Trays: £25-£60, but need frequent replacement
- Whitening Strips: £30-£60 per treatment course
- In-Office Professional Whitening: £400-£800 for a complete treatment
- Whitening Toothpaste: £5-£10 per tube, minimal results beyond surface stains
How important is the concentration of whitening gel?
The concentration of active ingredients directly impacts effectiveness. Professional-grade gels contain higher concentrations of whitening agents (typically 15-38% carbamide peroxide) compared to over-the-counter products (usually 3-15%). Higher concentrations work faster but may cause more sensitivity.
How long should I wear whitening trays?
- High-concentration gels: 30-60 minutes per application
- Medium-concentration gels: 2-4 hours
- Lower-concentration gels: overnight
Follow your dentist’s guidance for optimal results without unnecessary sensitivity.
Which provides faster results: trays or other whitening methods?
Custom trays with professional-strength gel typically provide faster results than whitening strips or over-the-counter kits. Studies show custom trays with 16% carbamide peroxide achieved results 2.5 times faster than leading whitening strips.
How can I maintain my whitening results for longer?
- Avoid highly pigmented foods and drinks for 48 hours after whitening
- Use a whitening toothpaste once or twice weekly to remove surface stains
- Consume staining beverages through a straw and rinse with water afterward
- Quit tobacco products which quickly undo whitening results
- Schedule brief maintenance treatments every 3-6 months
- Maintain regular dental hygiene appointments
