I must confess, I felt slightly baffled (and oddly intrigued) when a 'tooth cleanser' landed on my desk a few weeks ago. Dawood & Tanner Tooth Cleanser, £3.99 (Boots), might sound a bit pretentious but there's science behind the premise. Rather than erode the enamel, the gel's kind-to-the-teeth pH formula means your gnashers are gently buffed...an objective that is definitely noticeable during the cleansing process. For one, there's not a great deal of lather, and secondly, I didn't have to endure the 'burning' sensation of some other high street toothpastes. And still, my teeth felt lickably clean.
