Oral-B class action lawsuit overview:

  • Who: Plaintiff Alan Dalewitz has filed a class action lawsuit against the makers of Oral-B Glide dental floss.
  • Why: He says The Procter & Gamble Company misrepresented to consumers that the product was “Pro-Health” when it actually contains chemicals known to be toxic to humans.
  • Where: The Oral-B class action lawsuit was filed in New York federal court.

The Procter & Gamble Company has been hit with an Oral-B class action lawsuit alleging some of its dental floss products contain harmful “forever chemicals.”

Plaintiff Alan Dalewitz filed the Oral-B class action lawsuit on Aug. 26, claiming that Oral-B Glide Dental Floss products are marketed as “Pro-Health,” but laboratory testing shows that the dental floss likely contains per- and polyfluoroalkyl substances (PFAS).

PFAS are synthetic chemicals that are toxic to humans, even at low levels, the Oral-B class action lawsuit explains. This group of chemicals do not break down over time, a trait which has led them to be called “forever chemicals.”

Forever chemicals have been found in a large number of consumer goods, leading to a growing number of class action lawsuits seeking to hold companies accountable for putting consumers’ health at risk.

Testing suggests presence of PFAS in Glide dental floss, Oral-B class action says

Dalewitz says his attorneys have tested the Oral-B dental floss products and detected the presence of PFAS. The Oral-B class action lawsuit also points to a peer-reviewed study that has identified two specific types of PFAS in Oral-B Glide products.

The Oral-B forever chemicals allegedly include PTFE and PFHxS. PTFE is a major pollutant that allegedly has come under scrutiny recently over its safety, and PFHxS has reportedly been linked to adverse health effects such as liver damage, thyroid damage, and injuries to a developing fetus.

“Thus, P&G’s advertising of Oral-B Products–which suggests that the Product is ‘Pro-Health’–is false and misleading,” the Oral-B class action lawsuit alleges.

Dalewitz asserts that P&G’s allegedly misleading marketing of Oral-B dental floss has enabled it to sell more of the products and sell them at higher prices. He says the company had a responsibility to disclose the presence of Oral-B forever chemicals but failed to warn consumers about the presence of the toxic chemicals.

“No reasonable consumer would expect that a Product marketed for one’s health would contain dangerous PFAS, which are indisputably linked to harmful health effects in humans,” Dalewitz says.

He asserts claims for violations of New York consumer protection laws and fraudulent concealment.

The Oral-B class action lawsuit is not the only one P&G has faced recently. Earlier this year, P&G asked a New York federal judge to dismiss a class action lawsuit alleging its Crest charcoal toothpaste does not work as promised.

A shapeshifting robotic microswarm may perhaps one day act as a toothbrush, rinse, and dental floss in 1.

The technologies, developed by a multidisciplinary team at the University of Pennsylvania, is poised to give a new and automated way to conduct the mundane but vital day by day responsibilities of brushing and flossing. It is a process that could be especially useful for those people who deficiency the manual dexterity to clean their tooth successfully on their own.

The creating blocks of these microrobots are iron oxide nanoparticles that have both equally catalytic and magnetic exercise. Applying a magnetic discipline, researchers could immediate their motion and configuration to form both bristlelike structures that sweep away dental plaque from the wide surfaces of tooth, or elongated strings that can slip between enamel like a size of floss. In equally circumstances, a catalytic response drives the nanoparticles to produce antimicrobials that eliminate hazardous oral germs on internet site.

Experiments using this technique on mock and authentic human tooth confirmed that the robotic assemblies can conform to a selection of shapes to practically get rid of the sticky biofilms that direct to cavities and gum ailment. The Penn staff shared their results setting up a evidence-of-idea for the robotic procedure in the journal ACS Nano.

“Routine oral care is cumbersome and can pose difficulties for lots of people today, primarily these who have tough time cleaning their teeth” says Hyun (Michel) Koo, a professor in the Office of Orthodontics and divisions of Community Oral Wellbeing and Pediatric Dentistry in Penn’s Faculty of Dental Medication and co-corresponding writer on the research. “You have to brush your teeth, then floss your teeth, then rinse your mouth it’s a handbook, multistep process. The significant innovation listed here is that the robotics procedure can do all 3 in a single, palms-cost-free, automated way.”

“Nanoparticles can be shaped and controlled with magnetic fields in astonishing strategies,” states Edward Steager, a senior exploration investigator in Penn’s Faculty of Engineering and Used Science and co-corresponding creator. “We kind bristles that can increase, sweep, and even transfer again and forth throughout a space, significantly like flossing. The way it is effective is very similar to how a robotic arm could get to out and thoroughly clean a area. The method can be programmed to do the nanoparticle assembly and motion management quickly.”

Disrupting oral care technology

“The design of the toothbrush has remained fairly unchanged for millennia,” says Koo.

Though including electric powered motors elevated the standard “bristle-on-a-stick” format, the essential notion has remained the exact. “It’s a technological know-how that has not been disrupted in a long time.”

Quite a few years back, Penn researchers within just the Centre for Innovation & Precision Dentistry (CiPD), of which Koo is a co-director, took measures towards a important disruption, applying this microrobotics process.

Their innovation arose from a little bit of serendipity. Research teams in both of those Penn Dental Medicine and Penn Engineering were being fascinated in

As we have described before, dental floss has numerous simple makes use of outside of having crud out from in between your enamel. You can use it as thread, a stand-in for photo-hanging wire, and to aid “climbers” in your backyard. This pillar of proper oral hygiene can also cleanly and efficiently slice sure gentle foods—minus all the crumbling and caving a knife can result in. Listed here are some of the strategies you can put (unwaxed, unflavored) dental floss to superior use in your kitchen area.

Birthday cake: Whether you have created a cake by yourself or acquired a single at the retailer, if it has icing or decorations, slicing it can be a sensitive act. By pulling a extensive strand of (once again, unflavored) floss taut in between two fingers and firmly guiding it down throughout the size of the cake like a observed, you can make cleanse, un-crumbled slices, while maintaining the decorations intact. Slide the floss through the bottom of the cake (instead than lifting it again up), re-position, and do it yet again until you’ve obtained as numerous slices as you require.

Cheesecake: The very same system can be made use of on cheesecake, which is typically a hot mess to minimize. Exactly where slices of cheesecake will generally adhere to a knife or cake cutter, creating you to drag all the shrapnel by means of the relaxation of the cake, a strip of floss (held taut and slid by means of the bottom of the cake, as above) will provide significantly cleaner items.

Layer cake: For any person who’s specified on their own 1 hour to make a cake for an function (then recognized midway by means of: oh crap, it’s a layer cake), dental floss can come to the rescue. (Or if you just want to help save by yourself the headache of getting ready and cleansing two cake pans.) Comply with this technique of positioning several toothpicks halfway up the aspect of the cake, wrapping floss all over the cake (on top rated of the toothpicks) and pulling. (Or you can ditch the ruler and toothpicks and pull it freestyle, if you have to have a little excitement in your lifestyle.)

Goat cheese: Not only is goat cheese smooth, it’s crumbly—making it doubly tough to minimize without building a mess. For mere spreading, a knife will do the job. But if you want to attain those people high-hire searching cafe rounds—and you don’t have any cheese wire—pull some floss taut and slide it as a result of.

Mozzarella cheese: It is hard to develop non-stringy parts of mozzarella to go with those tomato slices and basil. Use
