​Professional Teeth Whitening in Hertfordshire

A brighter smile can make a significant difference to how you look and feel. At Paragondental, we offer professional teeth whitening to patients across Hertfordshire using the 360 Whitening system - a clinically proven, dentist-supervised treatment that delivers natural-looking results from the comfort of your own home, with virtually zero se nsitivity.

Unlike over-the-counter whitening products, professional teeth whitening can only be provided by a registered dental professional. At our practice in Radlett, your treatment is assessed, prescribed, and overseen by Dr Andrew Flatters, ensuring your whitening is safe, effective, and right for your teeth.

 

Why Professional Teeth Whitening?

Teeth naturally discolour over time. Tea, coffee, red wine, certain foods, and simply ageing all cause the enamel to yellow or stain. Professional whitening uses clinically approved bleaching gels at concentrations only available through a dental practice, to safely lighten teeth from within, rather than just removing surface stains.

Over-the-counter whitening products sold online or in shops are limited by law to much lower concentrations of active ingredient, and are not customised to your teeth. The result is typically underwhelming, and ill-fitting trays can cause gel to leak onto the gums and cause irritation.

Professional whitening at Paragondental is different. Your trays are made precisely to your teeth, the gel is dentist-prescribed, and the whole process is supervised to ensure the best possible outcome for your smile.

360 Whitening - Our Professional Whitening System

At Paragondental we use 360 Whitening, a professional-grade at-home whitening system used by dental practices across the UK. It has been specifically developed to deliver outstanding whitening results while minimising sensitivity - a common concern for many patients.

How it works

360 Whitening uses a dual-action gel that works in two ways simultaneously: penetrating deep into the tooth to lighten it from within, while also removing surface stains. The active ingredients form oxygen ions that gently and effectively lift discolouration without damaging the enamel.

The gel includes a unique trolamine formulation which acts as a desensitiser, stabilising the formula and making it suitable even for patients who have previously experienced sensitivity with whitening products.

Two formula options

Depending on your lifestyle and preference, 360 Whitening is available in two formats:

• Day formula - a fast-acting 6% hydrogen peroxide gel worn for one hour during the day. Ideal if you want to fit whitening into your daytime routine.

• Night formula - a 16% carbamide peroxide gel worn overnight for eight hours. The carbamide slowly converts to peroxide as you sleep, gently and comfortably whitening your teeth without you even noticing.

​​

Dr Flatters will recommend the most suitable option for you based on your lifestyle and the degree of whitening you are looking to achieve.

What to Expect - Your Whitening Journey at Paragondental

Step 1 - Initial assessment

Before any whitening treatment begins, Dr Flatters will carry out a full dental assessment to confirm your teeth and gums are healthy and that whitening is appropriate for you. If there is any decay, gum disease, or other issues that need addressing first, these will be treated before whitening begins. This is not a step you get with over-the-counter products — and it matters.

Step 2 - Digital impressions

We take precise digital impressions of your teeth using our intraoral scanner. These are sent directly to the 360 Whitening laboratory, where your bespoke whitening trays are hand-finished by technicians to ensure an accurate, comfortable fit. Well-fitting trays are essential — they keep the gel in contact with your teeth and away from your gums.

Step 3 - Tray fitting and demonstration

Around one to two weeks later, you come in to collect your custom trays. Dr Flatters will show you exactly how to apply the gel, how long to wear the trays, and what to expect during the process. You leave with everything you need to whiten your teeth at home.

Step 4 - Whiten at home

Most patients start to notice a visible difference within the first week. The full course typically takes two to four weeks depending on the degree of whitening required. Your trays are yours to keep — top-up gels can be purchased from the practice whenever you want to refresh your results in the future.

Is Teeth Whitening Right for You?

Teeth whitening is suitable for most adults with healthy teeth and gums. It is particularly effective for teeth that have become discoloured through:

• Tea, coffee, or red wine

• Smoking

• Ageing

• Certain medications

• General surface staining
   

It is worth noting that whitening gel works on natural tooth enamel only, it will not change the colour of crowns, veneers, bridges, or white fillings. If you have restorations on visible teeth, Dr Flatters will discuss this with you at your consultation and advise on the best approach. To see the kind of results professional whitening can achieve, please take a look at our Smile Gallery.
An important note - Whitening is not recommended during pregnancy or breastfeeding, and is generally not carried out on patients under 18.
