A dazzling, white smile can boost your confidence and make a lasting impression. Professional teeth whitening is often a safe, efficient, and highly effective method to enhance your smile.
In this guide, we’ll break down everything you need to know about professional teeth whitening, including the types of treatments, how they work, what to expect, and how to maintain your results.
How Does Professional Teeth Whitening Work?
Professional whitening uses hydrogen peroxide or carbamide peroxide. These release oxygen molecules that penetrate enamel and break down stains at the molecular level—unlike over-the-counter (OTC) products that scrub surface stains with abrasives.
Why Choose Professional Whitening Over OTC Products?
OTC products have lower peroxide concentrations. Dentists can safely apply higher levels (up to 40%) using gum shields and other protective tools for quicker and more effective results with minimal irritation.
Types of Professional Teeth Whitening Treatments
1. In-Office Whitening
In-office treatments give fast, dramatic results—often in one visit. High-concentration gel is applied, sometimes activated with light or laser.
Common Methods:- 15–30 minute gel applications
- Light-activated whitening (LED, UV, halogen)
📚 Studies show halogen and laser lights may offer longer-lasting results than gel alone.
Is Light Activation Safe?
Yes. According to a 2020 study in Materials, LED-assisted whitening is generally safe. Side effects like sensitivity are usually temporary.
What to Expect:
- Tooth shade assessment
- Tooth polishing
- Protection of gums, cheeks, tongue
- Whitening gel application
- Possible light activation
- Rinse and optional fluoride
- Aftercare instructions
2. Custom Take-Home Whitening Trays
A flexible option used independently or after in-office whitening. Dentists create custom trays based on your teeth impressions. The gel (10–38% carbamide peroxide) is worn 2–10 hours per day for up to 28 days.
Custom trays ensure even whitening and reduce gum irritation—something OTC kits often fail to do.
In-Office Whitening vs. Take-Home Trays
| Factor | In-Office Whitening | Custom Take-Home Trays |
|---|---|---|
| Cost | £640–£800 | £240–£480 |
| Time Commitment | 1–2 appointments, 60–90 mins | Daily use for up to 4 weeks |
| Speed of Results | Immediate | Gradual |
| Longevity | Months to 1+ year | 3–5 years |

Maintaining Your Whitening Results
