Smile Science Smile Science Whitening Strips Achieve professional-level teeth whitening from the comfort of your own home with Smile Science Harley Street Teeth Whitening Strips. Designed to deliver fast, visible results, teeth appear noticeably brighter within the first few days, with up to 6 shades of whitening after completing the full 14-day treatment. This advanced formula has been carefully developed for sensitive teeth, providing effective whitening without discomfort. Our next-generation whitening strips were created by a world-renowned dentist best known for pioneering industry-leading innovations such as Colgate Total and Philips Zoom. This professional-grade formulation works to remove surface stains in just 30 minutes per treatment over a simple 14-day course, delivering reliable, salon-quality results at home. What makes these strips stand out is their enamel-friendly composition. Specially formulated for sensitive teeth, they are gentle on gums and tooth enamel, ensuring no irritation, no sensitivity, and a comfortable whitening experience from start to finish. The proprietary whitening gel features an elastic consistency combined with advanced mould technology, allowing the strips to adhere securely to the teeth for maximum contact and effectiveness. Using a low-level hydrogen peroxide ingredient, the formula targets both deep-set and surface stains caused by coffee, tea, red wine, smoking, and natural ageing. The result is intensive stain removal and a visibly whiter, more radiant smile you can feel confident about. These whitening strips offer a convenient and effective solution for achieving the bright smile you've always wanted, while gently whitening without compromising enamel health. As an award-winning leader in UK teeth whitening, Smile Science also offers a full range of maintenance products, including whitening pens for on-the-go touch-ups and daily-use whitening toothpastes and tablets for optimal oral care and long-lasting brightness.
