Which floss is strongest?

Waxed floss tends to be stronger than the unwaxed, and less likely to shred between the teeth. Adding this wax coating does increase the thickness of the floss which may make it unusable for people with very tight gaps between their teeth. Unwaxed floss is better for use in the tightest of spaces in the mouth.

Which type of dental floss is better?

waxedThe waxed variety of dental floss tends to glide through the teeth better. Waxed floss is less likely to get stuck between the teeth or get caught on rough edges. It also doesn't fray or break as quickly as unwaxed dental floss.

Which dental floss is toxic?

Oral-B Glide and similar competitor flosses can expose consumers to toxic chemicals, concludes a new study . The authors of the study say this is the first time that the use of certain varieties of dental floss is associated with higher concentrations of chemicals known as PFAS, or polyfluoroalkyl substances.

Is waxed floss better than unwaxed?

Patients with tightly spaced teeth may find it easier to use waxed floss due to its natural lubricating property. Waxed floss is usually stronger than unwaxed, meaning it won't break as much during flossing. Unwaxed floss, on the other hand, is thinner and more comfortable to move in and out of your teeth.

Does Oral-B Glide floss have Teflon?

Some types of dental floss, Oral-B Glide for example, are formulated with polytetrafluoroethylene (Teflon) to facilitate insertion between teeth. In the study in question, the researchers present data showing that people who use this type of dental floss have higher levels of some PFAS in their blood than non-users.

How many different types of dental floss are there?

Which toothbrush or toothpaste is best for you depends on your unique dental condition, but did you know that the same is true of floss? There are 5 main types of floss and each have their own advantages and disadvantages.

Which floss is better waxed or unwaxed?

Does the type of dental floss matter?

We do not push a certain type of floss on patients; we just want to know that you are flossing because it is the number one way to prevent gum disease and even the subsequent risk of heart attack or stroke. Do not skip flossing your teeth at least once a day or more often if you have food stuck in between your teeth.

Are all dental floss the same?

There are different types of people with different types of teeth! The typical floss most often found in dental offices and dental freebies is a nylon, waxed floss.

What is PTFE in chemical terms?

Chemical compound. Polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The commonly known brand name of PTFE-based compositions is Teflon ™ by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938. Polytetrafluoroethylene is a fluorocarbon solid (at room ...

What is GenX used for?

As a result of the lawsuits concerning the PFOA class-action lawsuit, DuPont began to use GenX, a similarly fluorinated compound, as a replacement for polytetrafluoroethylene in the manufacture of fluoropolymers, such as Teflon.

Why is tetrafluoroethylene used in polymerization?

Because tetrafluoroethylene can explosively decompose to tetrafluoromethane and carbon, special apparatus is required for the polymerization to prevent hot spots that might initiate this dangerous side reaction . The process is typically initiated with persulfate, which homolyzes to generate sulfate radicals:

How is PTFE made?

Some PTFE parts are made by cold-moulding, a form of compression molding. Here, fine powdered PTFE is forced into a mould under high pressure (10–100 MPa). After a settling period, lasting from minutes to days, the mould is heated at 360 to 380 °C (680 to 716 °F), allowing the fine particles to fuse ( sinter) into a single mass.

What temperature does PTFE melt?

PTFE is a thermoplastic polymer, which is a white solid at room temperature, with a density of about 2200 kg/m 3 and a melting point of 600 K (327 °C; 620 °F). It maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (−268.15 °C; −450.67 °F), and good flexibility at temperatures above 194 K (−79 °C; −110 °F). PTFE gains its properties from the aggregate effect of carbon-fluorine bonds, as do all fluorocarbons. The only chemicals known to affect these carbon-fluorine bonds are highly reactive metals like the alkali metals, and at higher temperatures also such metals as aluminum and magnesium, and fluorinating agents such as xenon difluoride and cobalt (III) fluoride. At temperatures above 650–700 °C (1,200–1,290 °F) PTFE undergoes depolymerization.

When was polytetrafluoroethylene discovered?

Polytetrafluoroethylene was accidentally discovered in 1938 by Roy J. Plunkett while he was working in New Jersey for DuPont. As Plunkett attempted to make a new chlorofluorocarbon refrigerant, the tetrafluoroethylene gas in its pressure bottle stopped flowing before the bottle's weight had dropped to the point signaling "empty." Since Plunkett was measuring the amount of gas used by weighing the bottle, he became curious as to the source of the weight, and finally resorted to sawing the bottle apart. He found the bottle's interior coated with a waxy white material that was oddly slippery. Analysis showed that it was polymerized perfluoroethylene, with the iron from the inside of the container having acted as a catalyst at high pressure. Kinetic Chemicals patented the new fluorinated plastic (analogous to the already known polyethylene) in 1941, and registered the Teflon trademark in 1945.

Where is GenX manufactured?

The chemicals are manufactured by Chemours, a corporate spin-off of DuPont, in Fayetteville, North Carolina. While PFOA was phased out by 2014, Chemours was already found to be dumping GenX into the Cape Fear River in 2017, with the North Carolina Department of Environmental Quality (NCDEQ) ordering Chemours to halt discharges of all fluorinated compounds on September 5, 2017.

What is PFAS in dental floss?

PFAS is an umbrella term for a group of related man-made chemicals used in many different consumer products.

Why are PFAS used in products?

Why PFAS are used in products. PFAS are highly prized in certain industries for their “nonstick” or slippery properties. Teflon, a famous brand of material used to create nonstick cookware is derived from polytetrafluoroethylene (PTFE), part of the family of PFAS chemicals. ‘Glide’ flosses are also made using PTFE.

How many flosses tested positive for fluorine?

Only 6 of the 18 flosses tested positive for fluorine — meaning that two-thirds were free of PFAS. “Historically, the traditional floss has been around a long time. It’s made out of dakron and wax and it’s quite effective,” said Ronald P. Uilkie, DDS, a practicing dentist based in New Mexico.

How does PFAS affect fertility?

PFAS are also endocrine disrupting chemicals, meaning they affect the body’s hormone production. This can result in learning, behavioral, and growth problems in children. They can also affect fertility in both men and women. “Once they are in the body, they hang around for a few years. That’s one of the concerns.

When were PFAS made?

PFAS have been produced since the 1940s and are used in everything from cookware and electronics to fast food wrappers and paints.

Does floss cause PFAS?

Some of these behaviors (consumption of fast food, floss usage) were associated with higher levels of serum PFAS, while others (use of nonstick cookware and consuming microwave popcorn) were not.

Do flosses contain PFAS?

Uilkie is now concerned that this study could undermine the work it has taken over the years to get people to floss, despite the fact that most flosses do not contain any PFAS chemicals. “Some people are going to use this as an excuse to stop flossing again.

What does PFAS stand for in dental floss?

PFAS stands for a tongue twister: polyfluoroalkyl substances. They’re found in lots of nonstick chemicals and they are suspected of causing substantial mischief, including thyroid problems.

What is a PFAS?
