From morning coffee to evening red wine, daily habits leave their mark on your teeth over time. Our clinical-grade whitening gels break down both internal and external pigments — lifting discolouration from coffee, tea, red wine, smoking, and certain medications — all without removing any of the tooth's surface. For Jersey residents looking to reverse years of staining, professional whitening delivers results that no over-the-counter product can match.

Teeth naturally darken with age, but whitening can turn back the clock. By brightening your smile several shades, treatment reduces visible signs of ageing and gives you a fresher, more confident appearance — all in just one or two visits to our St Helier practice.

Whether it's a wedding, a job interview, or simply wanting to feel your best day-to-day, a whiter smile has a real impact on self-esteem. Many of our Jersey patients tell us it's one of the most confidence-boosting treatments they've ever had.

Unlike home kits bought online, treatment at New Street Dental is dentist-led from start to finish. We assess your suitability beforehand, monitor sensitivity throughout, and ensure your results are consistent and long-lasting — giving you peace of mind that your smile is in expert hands right here in Jersey.

Temporary tooth sensitivity is a very common side effect that can occur either during or shortly after a teeth whitening treatment. For the vast majority of patients, this discomfort is mild and resolves quickly on its own within 24 to 48 hours with the right aftercare.

It is possible for whitening agents to occasionally irritate the gums if the active gel comes into direct contact with the soft tissues of your mouth. Fortunately, this gum irritation is generally very mild, completely harmless, and short-lived, typically resolving naturally within 24 to 48 hours without any lasting damage.

It is entirely possible for teeth whitening to produce slightly uneven results initially. This happens because existing dental restorations—such as crowns, veneers, bridges, or white composite fillings—do not respond to whitening gels and will remain their original colour. Additionally, certain types of deep structural stains or natural variations in enamel thickness can cause individual teeth to whiten at different speeds, temporarily affecting the uniformity of your smile.

It is entirely possible to over-whiten your teeth. Overusing whitening gels, leaving them on for too long, or turning to illegal, non-dentist-led whitening treatments can permanently harm your tooth enamel, trigger severe tooth sensitivity, and cause lasting damage to your gums.

Whitening starts from £325 here at New Street Dental. That covers your assessment, a set of custom-made trays moulded to your teeth, and a course of professional-strength whitening gel. We'll check your smile is suitable for whitening first, here in St Helier, Jersey, and give you a clear price before you start, so there's nothing unexpected along the way.

A couple of things shape the final figure. The type and depth of staining matter, as more stubborn discolouration from years of coffee, tea, or red wine can call for a longer course to reach the shade you're after. Whitening both arches rather than one plays a part too. And once your custom trays are made, they last for years, so any future top-ups only mean paying for fresh gel rather than starting over.

It's worth knowing why dentist-led whitening costs more than a kit off the shelf. In the UK, only GDC-registered dental professionals can legally carry out teeth whitening, because professional-strength gel has to be used safely and under supervision. Your custom trays are made to fit your teeth precisely, which protects your gums and spreads the gel evenly for consistent results. Cheaper online kits are either too weak to do much or, in some cases, illegally strong and a real risk to your enamel and gums. With us, your whitening is assessed, supervised, and done properly from start to finish.
