In the UK, a toothpaste has been launched that rebuilds tooth enamel, writes "The Telegraph".
The paste clogs the teeth with a layer of liquid calcium, the mineral from which the enamel is built, which helps the teeth repair themselves. Calcium protects the teeth from the appearance of chariots, but also the exposed nerves, thus preventing pain.
Toothpaste Enamel Care Sensitive, created by Arm and Hammer, is the first to try to eliminate the cause of tooth sensitivity instead of masking it.
The treatment is intended especially for people who suffer from sensitive teeth. In the United Kingdom alone, their number rises to 13 million, and the costs of the treatments amount to almost 90 million euros per year.
Graham Barnby, the dentist in charge of testing the product, said the improvements were noted after just two weeks.
Arm and Hammer representatives said: "Toothpaste contains eight times more calcium which, in combination with saliva, covers the teeth and contributes to the restoration of enamel."
Teeth sensitivity is a problem that occurs in most elderly people, because the gums shrink or the enamel is eroded due to acidic foods or drinks.
