Professional Teeth Whitening at Devonshire House, Brentwood

At Devonshire House, we use Philips Zoom WhiteSpeed, one of the most trusted and widely used professional whitening systems in the world. Capable of brightening teeth by up to six shades in a single one-hour appointment, Zoom WhiteSpeed delivers fast, safe, and dramatic results. It's the preferred choice for patients across Brentwood and Essex who want a noticeably whiter smile without compromise.

Before any whitening treatment begins, our team carries out a thorough assessment of your oral health to ensure you're a suitable candidate. We then take precise impressions of your teeth to create custom-fitted whitening trays, which ensure even coverage and maximum comfort throughout the process. Your gums and soft tissues are carefully protected before the Zoom whitening gel is applied and activated using the WhiteSpeed lamp — accelerating the whitening process while keeping your teeth safe and healthy.

Once your treatment is complete, we don't just send you on your way. Our team provides full aftercare guidance to help you get the most from your results. We also supply Opalescence take-home whitening gel so you can top up your treatment at home and keep your smile looking its best. Alongside this, we'll share practical advice on diet and lifestyle habits to help minimise future staining and extend the life of your results.

Prefer to whiten at your own pace? We also offer Philips DayWhite and NiteWhite home whitening kits for patients who want the flexibility of treating their teeth at home. These clinically proven, professionally supervised kits come with custom-fitted trays and EU-compliant whitening gels, giving you safe, effective results with minimal sensitivity — on a schedule that works for you.

Results vary from patient to patient depending on factors such as the degree of staining, tooth sensitivity, and how well aftercare advice is followed. Some patients see a significant difference after just one in-practice session, while others benefit from combining in-chair treatment with a home kit for more progressive results. With the right maintenance routine, professional teeth whitening can deliver long-lasting brightness and a real boost to your confidence.

Professional teeth whitening is a safe, well-tolerated treatment when carried out under the supervision of a qualified dental team. A small number of patients experience mild, temporary tooth sensitivity or slight gum irritation, but our team takes every precaution to minimise any discomfort. We customise every treatment protocol and use desensitising agents where needed to ensure your experience is as comfortable as possible.

To make the most of your whitening results, good oral hygiene is key. Brushing twice daily, flossing regularly, and keeping up with your routine dental check-ups at our Brentwood practice will all help maintain your results. Cutting back on staining food and drinks where possible — such as coffee, tea, and dark-coloured berries — will also go a long way in preserving that fresh, white smile for longer.
