Too young children use too many toothpastes, increasing the risk of striped or defiant teeth when they become older, according to a government survey released Thursday.
About 40 percent of children aged 3 to 6 used a brush that was full or half full of toothpaste, although experts recommend no more than the amount of pea size, a study showed.
Findings of Centers for Disease Control and Prevention are based on a parents' survey of more than 5,000 children aged 3 to 15 years.
Health workers recommend that all people drink fluoride water and all 2 or older drink twice a day with toothpaste fluoride.
But the amount is important. Children under 3 years of age should use only the stain paste of rice grain size. Children aged 3 to 6 should keep it to pea size.
"Fluoride is a great benefit, but it needs to be used carefully," said Dr. Mary Hays, a pediatric dentist in Chicago.
Young children can insist on the independence of tooth brushing, but the children's toothpaste has sweet tastes.
"You do not want to eat it like food," Haies said. "We want the parent to be in charge of the toothbrush and toothpaste."
Fluorine is a mineral found in water and soil. More than 70 years ago, scientists found that people whose drinking water naturally has more fluoride also have less cavities. This led to the effort to add fluoride to tap water, toothpaste, mouthwash, and other products. Experts say fluoride helped reduce the rate of tooth decay in the United States and teenagers and adults.
But too much fluoride when the teeth are formed can lead to tooth breaks or fissures – known as dental fluorosis. In extreme cases, teeth can be ejected from the minerals, although many cases are so gentle that only dentists notice it.
Previous studies have shown that fluoride increases for at least three decades and can affect as many as 2 out of 5 adolescents.
The new study did not keep track of children in time or tried to determine how many developed striped or bellied teeth were created by using too many toothpastes.
Authors have confirmed other restrictions. Parents may have mistakenly remembered how many children to use when they were younger. Also, the survey did not specifically ask about the types of toothpaste used; They do not have all kinds of toothpaste.
The study showed that about 60% of children are washing their teeth twice a day. It has also been found that about 20% of white and black children, and 30% of Hispanic children, did not start brushing until they were three or more years old.
