Close up deep action tooth paste is one of the most familier toothpastes available in the market.i used this toothpaste for six months.i found that the flavour is very nice and the odour is also nice but the thing is it may cause some problems.i obsreved a problem by using this toothpaste that is, it gradually weakens the teeth enamel and may lead to break the enamel when we used to eat some strong foods.i personally experienced this problem so I don’t suggest anybody to use this product.
