Dental sensitivity is a growing problem as the population ages and teeth become more sensitive as a result of gum recession or erosion of the enamel by acidic food and drink. Current toothpastes aimed at people with sensitive teeth simply cover the pain. Experts have made new toothpaste that promises to end the agony of sensitive teeth by rebuilding tooth enamel. The new treatment states to be the first on the market that actually treats the causes of sensitive teeth. Calcium rebuilds the tooth by plugging microscopic gaps in the enamel. The repair stops dental nerves becoming exposed, preventing pain. The makers claim that the toothpaste has eight times the amount of calcium in saliva; it coats the teeth and encourages the enamel to recover.

The makers of Arm & Hammer's Enamel Care are hoping the product will attract some of the £60 million a year spent on treatments by those for whom simple pleasures such as drinking a cup of tea or eating ice cream can be unbearable. The toothpaste will be available in Britain at the end of this month priced at £3.49 for a 75ml tube, before going on sale in the U.S.
