Experts question benefits of fluoride-free toothpaste - the best toothbrush

Dental health experts worry that toothpaste used by more people will ignore the most important ingredients --fluoride —
Put them at greater risk of tooth decay.
Most toothpaste already contains fluoride.
While the health authorities recognize fluoride as a cavity inhibitor, there are a number of claims circulating on the Internet, often from "natural" toothpaste marketers and alternative medical advocates, namely fluoride-
Free toothpaste can also prevent tooth decay.
The dental authorities did not agree.
"It is very important to expose the idea of brushing your teeth to stop rotting.
You need to have fluoride, "said Damien Walmsley, a science consultant at the British Dental Association and a professor of dentistry at the University of Birmingham.
This week, an article in The Journal of Dentistry, gerontology, highlighted this point of view, which reviews scientific literature on cavities.
Its main conclusion is that, without fluorine, oral hygiene efforts "have no effect" on oral rate ".
For decades, the idea that brushing teeth alone does not stop tooth decay has been widely accepted among individual researchers, but is not always accepted by the public.
Dentists often recommend the use of fluoride to fight tooth decay, but even if some of them still believe that the mechanism of cleaning plaque will reduce tooth decay.
The results of the comments released on Monday put at least one dentist on hold.
"This is against certain principles that we have been taught, that we teach and that we believe in," said Richard neidman, a dentist and professor at New York University who saw the pre-release of the study, the results are believed to be credible.
"It tells me that the toothbrush is just a delivery system.
"In recent years, there has been very little research on this issue because the value of fluoride has been widely accepted for decades.
In the review, researchers at the University of Washington looked for high
Only three quality studies have been found since 1950.
They were implemented in the United States. S.
Published in the UK from 1977 to 1981.
They involved a total of 743 children between the ages of 10 and 13 who had been brushing with floss and floss for three years.
When these studies were statistically evaluated as a whole, there was no significant cavity reduction in simply brushing teeth or using dental floss without fluorine. Dentist J.

P & G, a toothpaste maker, said the comment was "an important reminder.
"Despite the large amount of scientific evidence, more and more consumers believe that all toothpaste is the same, as long as you effectively clean your teeth with a toothbrush or other equipment that cleans your teeth
"Between teeth, you can prevent rot," he said in a statement . ".
Market share of fluoride
According to company data, free toothpaste has attracted much attention.
Industry insiders estimate that this ratio does not exceed 5 of all toothpaste sold, but is expected to grow more than 5 per year.

Free, listed as second
Amazon buys the best-selling toothpaste on the platform online.
Paul Jessen, brand manager at Tom's, Maine, said, "the fluorine-free products we offer do not guarantee the benefits of fighting tooth decay ".
He said that was generally understood by his company's customers.
However, customer reviews on Amazon's website sometimes indicate that this is not the case, and many of them insist that the company's fluorine-
Free toothpaste does fight tooth decay.
"If you brush your teeth regularly, whether there is fluoride or not, you will reduce the risk of tooth decay," one customer asserted . ".
The oral care company itself fell into this statement.
Revitin of the website
Fluoride toothpaste says it "enhances your teeth and prevents tooth decay.
Gerald coolatola, the dentist who founded Revitin and now serves as chief science officer, called the comment "misleading ".
The latest science suggests that the healthy combination of oral bacteria is key to dental health, he said.
"I don't think there's any difference in fluoride at all," he said . ".
However, referring to the decline of his company,
He added: "After receiving this call, I may remove it from the site because I don't think it should be on the site because I don't know what it says
Jeff Davis, CEO of Sheffield Pharmaceutical, which sells fluorine-containing and fluorine-free toothpaste, said fluorine helps reduce tooth decay, which is "very sure ".
But he said that some people are concerned about the harmful effects of excessive fluoride, so choose fluorine-Free toothpaste.
Even without fluorine, the dentist says brushing your teeth has some value.
The dentist who presided over the dental examination and professor at the University of Washington, Philip huyol, said that oral hygiene without fluorine could produce a real mouth --
Combat effects are too small to detect in a study, or in the absence of children in the study, adults may benefit.
In Hujoel's comments, brushing your teeth does reduce the swelling of the gums.
Brushing your teeth can also remove food and help patients recover from oral surgery.
Matthew Messina, a spokesman for the American Dental Association, said that mechanical brushing of teeth also helps to avoid the often hidden roots of teeth that sometimes rot, especially the elderly, which is beyond the scope of this review.
He added: "This study is important because it supports what we have been fighting for a long time.
Fluoride toothpaste is recommended by ADA.
The review also cited a 2009 analysis of studies involving 60,000 people that found that fluoride flushing can prevent tooth decay about the same as fluoride toothpaste.
In 2016, the Associated Press reported poor scientific evidence of the benefits of using dental floss.
So the federal government canceled its long term
Standing Dental floss recommended in American dietary guidelines.
This review raises questions about how the cavity is formed.
For a long time, it has been believed that when the acid left by the Food begins to wear the enamel, the mouth will form in a poorly cleaned mouth.
Clean teeth do not rot.
However, this review defends another pattern: Tooth Decay grows in small cracks in enamel and it is not easy to reach with a toothbrush or floss alone.
Despite the obvious benefits of fluorine, some studies have also questioned the belief that fluoride-containing drinking water can prevent tooth decay or fluoride toothpaste or flushing.
Niederman, a dentist at New York University, said that in any case, it would make sense to combine fluorine-added water with dental products to enhance protection.
Some dentists also say that the most effective way to prevent tooth decay is to reduce sugar in your diet.
