Teeth Whitening in Archway, North London
Professional teeth whitening is the safest, most effective and most cost-efficient way to brighten your smile. At Blue Light Dental & Aesthetic Clinic, we offer both in-chair whitening for dramatic same-day results and custom take-home kits for a more gradual approach — both using clinically proven systems not available over the counter.
In-chair Philips Zoom WhiteSpeed whitening
Our in-chair treatment uses the Philips Zoom WhiteSpeed system — a blue LED-activated whitening gel applied and refreshed over approximately one hour. Most patients see their teeth whiten by several shades in a single visit. Ideal if you want a noticeable result before an event or simply prefer the speed and simplicity of in-practice treatment.
Custom take-home whitening
We take precise impressions to create custom-fitted whitening trays that deliver professional-strength gel exactly where it’s needed. Results build gradually over two to three weeks and are typically excellent. Take-home kits are also ideal for topping up your in-chair result in future.
Is teeth whitening safe?
When prescribed and supervised by a registered dental professional, teeth whitening is a very safe and well-researched procedure. Over-the-counter products sold in shops or at non-dental beauty clinics do not use prescription-strength gel — and are not regulated to the same standards. We strongly advise whitening only through a qualified dentist.
Frequently asked questions
Will whitening damage my enamel? Professional whitening gel, used correctly under dental supervision, does not damage enamel. Temporary sensitivity is common for 24–48 hours after treatment and resolves on its own.
How long do results last? Results typically last 12–24 months, depending on diet and habits. We recommend periodic top-up treatments using your custom trays to maintain your shade.
Can I whiten if I have crowns or veneers? Whitening gel does not lighten porcelain or composite materials. We’ll discuss whether whitening is suitable before treatment and plan accordingly.
