Sensodyne Repair & Protect Toothpaste This new formulation added to the Sensodyne range is the first everyday fluoride toothpaste to contain patented Nova Min technology, which is scientifically proven to repair* sensitive teeth by forming a tooth-like layer over exposed dentine to help continually repair & protect sensitive areas. Sensitive teeth are common, affecting up to 81% of adults in the UK, yet many do not know that the twinges they experience are a sign of sensitivity which is caused by exposed dentine. Rather than addressing the problem, a large number of sufferers try to ignore the twinges or develop ways to avoid them, without realising their teeth have vulnerable areas. Professor David Bartlett explained: " Tooth sensitivity is caused when the dentine is exposed. This dentine that makes up most of the tooth is porous, with thousands of tiny channels running through it to a nerve in the centre. A layer of hard enamel on the crown of a tooth protects the underlying dentine, but if this dentine is exposed, a tooth can become sensitive & vulnerable." Using Sensodyne Repair & Protect twice daily, as you would a regular toothpaste; Sensodyne Repair & Protect will continually help repair sensitive teeth & help prevent sensitivity. Plus, it provides the benefits of an ordinary daily fluoride toothpaste, including all-round protection, cleaning & freshness. * Repair provides clinically proven relief with twice daily brushing
