What is the reason for flouride in the toothpaste?

The reason for adding flouride in toothpaste is that it helps to prevent tooth decay by slowing the breakdown of enamel and increasing the rate of the remineralization process. 

Fluoride is a naturally occurring mineral found in water in varying amounts, depending on where in the UK you live. It can help prevent tooth decay, which is why it's added to many brands of toothpaste and, in some areas, to the water supply through a process called fluoridation.
