NEW YORK (Reuters Health) – Many young children use a lot of toothpaste, increasing the risk of getting cracked and spotted teeth when they grow older, according to a US survey.
The study found that about 40 percent of children aged three to six years used a toothbrush that was full or half filled with toothpaste, although experts do not recommend more than the size of a pea.
The Centers for Disease Control and Prevention (CDC) based a survey of parents of more than 5,000 children between the ages of 3 and 15.
It is known that the toothpaste tube is almost empty of an invisible substance called fluoride, many studies say it has the ability to resist decay.
Health officials recommend that everyone drink “fluoridated water” and that every person from the age of 2 wash his teeth twice a day with toothpaste containing fluoride.
However, intensive use of fluoride when forming teeth can lead to tooth decay or sunken tooth, known as tooth fluorosis. In extreme cases, teeth can become covered with metal in full.
Previous studies have indicated that fluorosis has been on the rise for at least three decades, and that poisoning can affect two out of every five teenagers.
