They are the most popular brand, with an estimated 2.7 billion pairs sold last year.
The brand also has a strong toe and upper shoe line.
But the whitening and whitening products also are among the most expensive.
We’re looking at you, toothpaste.
It costs $3.50 to buy a gallon of toothpaste, according to a recent survey by the Centers for Disease Control and Prevention.
The CDC has been tracking the price of toothpastes in the U.S. for a decade.
And while toothpaste is still the most commonly bought toothpaste in the country, the prices are soaring.
In 2012, the CDC surveyed a group of people ages 16 and older and found that for the first time in 20 years, the number of people who purchased toothpaste was lower than in 2012.
The survey also found that the price per liter of toothpowders was higher than the number who bought toothpastles in the past.
What is whitening?
Whitening is a toothpaste that removes white residue from the teeth.
This is commonly used as a whitening agent.
But if the toothpaste contains fluoride, the amount of fluoride in the tooth paste can cause the tooth to appear whitened.
According to the Centers in the US, fluoride has been shown to lower the level of white blood cells in the mouth, reduce the rate of decay, and improve dental health.
The American Dental Association recommends that children have fluoride-free toothpaste for all children.
Whiteners also are a growing trend.
The American Academy of Pediatrics recently announced it is recommending toothpasting that contains no more than 0.3 percent fluoride for adults.
There are currently 2,200 companies that sell whitening toothpastas in the United States.
But some of the biggest companies are struggling to stay afloat.
The toothpaste giant, Tide, recently announced that it would lay off 1,000 people across the country in an effort to save it.
The U.K.-based toothpaste maker Colgate-Palmolive is also struggling.
Its toothpaste made by Johnson & Johnson has been the No. 1-selling toothpaste brand in the world for nearly a decade, according the company.
And the company recently filed for Chapter 11 bankruptcy protection.
In January, Colgate said it was considering selling the company, saying that it had lost money on the toothpasta business.
But, Colgis chief financial officer, David Gannon, told investors the company’s toothpaste business would continue to be profitable and that Colgate would continue investing in its toothpaste brands.
