Professional teeth whitening is a dentist-supervised process that uses carbamide or hydrogen peroxide gels to penetrate enamel and break down stain molecules.

Among younger adults, four in ten people under 35 have already undergone tooth-whitening treatments, highlighting particularly strong demand in that age group. 

Only natural tooth structure can be whitened—restorations such as crowns or veneers remain their existing colour. Unlike over-the-counter kits, professional treatments deliver higher concentrations of bleaching agents, producing faster and more dramatic shade improvements.

How Does A1 Dental Surgery Perform Whitening Safely?

At A1 Dental Surgery, we take an initial shade assessment and oral health check to confirm suitability for whitening. A customised tray is made for your teeth, ensuring the bleaching gel only contacts enamel and not gums.

Teeth whitening treatments are overseen by our GDC-registered dentists in line with British Dental Association guidelines, with emergency care protocols in place to manage any sensitivity or irritation.

What Are the Potential Side Effects and How Are They Managed?

Some patients experience temporary tooth sensitivity or mild gum irritation, usually resolving within 24–48 hours. A1 Dental Surgery mitigates these effects by using desensitising agents in the gel and providing post-treatment fluoride rinses if needed. In rare cases of severe sensitivity, bleaching concentration can be reduced or treatment paused until symptoms subside.

How Long Do Whitening Results Last and How Can You Maintain Them?

Results can last from six months up to three years, influenced by your consumption of staining foods—coffee, tea, red wine—and smoking habits.

To prolong your new shade, we recommend touch-up bleach gel applications every two to three months and good oral hygiene practices: brushing twice daily, flossing, and using a non-abrasive whitening toothpaste sparingly. Avoiding highly pigmented foods or using a straw for beverages can also help maintain results.

How Much Does Professional Whitening Cost at A1 Dental Surgery?

In the UK, professional whitening typically costs between £350 and £1,000 depending on the method and number of sessions. At A1 Dental Surgery, our bespoke whitening trays and gels start from £398, offering excellent value with a personalised treatment plan and aftercare support included.
