Tongue scraping has long been part of daily hygiene routines in many parts of the world.

Key Points: 
  • Tongue scraping has long been part of daily hygiene routines in many parts of the world.
  • But while there’s some evidence to back these claims, the practise could also come with risks.
  • Poor oral health can lead to a build-up of biofilms containing certain bacterial species which cause dental decay (cavities), gum disease and bad breath.
  • But there’s less evidence showing whether these techniques are also effective for preventing tongue biofilms and bad breath.

Tongue scraping

  • However, these reviews did find that the benefits of tongue scraping were shortlived and needed to be done using a specific technique to be effective.
  • There are other caveats when it comes to tongue scraping.
  • In these instances, tongue scraping will do little to solve bad breath.
  • One study has suggested that tongue scraping may actually enrich the amount of nitrate-reducing bacteria on the tongue.
  • It will be important for further research to be done with more participants to better determine both the potential benefits and harms of tongue scraping.

Should I use a tongue scraper?

  • It’s also likely that the benefits and downsides of using a tongue scraper would differ for each person.
  • Good oral hygiene will probably be enough to fix bad breath – and aggressive tongue scraping may actually risk making your tongue bleed.
  • We also don’t yet fully know how tongue scraping will affect good bacteria on you tongue.
  • Scrape your tongue, or clean your tongue with a toothbrush, with care, if you must.

Penn Dental Medicine Study Identifies New Bacterial Species Involved in Tooth Decay

PHILADELPHIA, July 28, 2023 /PRNewswire/ -- Collaborating researchers from Penn Dental Medicine and the University of North Carolina (UNC) have discovered that the bacterial species Selenomonas sputigena can have an important role in tooth decay.

Key Points: 
  • PHILADELPHIA, July 28, 2023 /PRNewswire/ -- Collaborating researchers from Penn Dental Medicine and the University of North Carolina (UNC) have discovered that the bacterial species Selenomonas sputigena can have an important role in tooth decay.
  • Scientists have long considered another bacterial species, the plaque-forming, acid-making Streptococcus mutans, as the principal cause of tooth decay—also known as caries.
  • Scientists in past studies of plaque bacterial contents have identified a variety of other species in addition to S. mutans.
  • This new study is the first to identify a cavity-causing role for a specific Selenomonas species.

Humans weren't the first engineers, doctors and farmers – bacteria, plants and animals have lots to teach us

Yet we often ignore the achievements of species that preceded us by billions of years.

Key Points: 
  • Yet we often ignore the achievements of species that preceded us by billions of years.
  • Bacteria, plants, fungi, insects, birds, whales and other species demonstrate language, engineering, science, medicine, agriculture and more.

Speaking nature’s language

    • Now, scientists from around the world are collaborating as part of the Cetacean Translation Initiative to use powerful AI algorithms and decode the language of sperm whales.
    • Plants communicate with each other using hormones such as jasmonate, which redirects resources from growth to repairing damage.
    • Meanwhile, bacteria have been “talking” to each other for billions of years by exchanging chemical messages via hormone-like molecules called autoinducers.
    • Studies into premature babies have shown the relationship between gut bacteria and human cells are crucial for cognitive development.

Skilled engineers

    • It is a permanent building site where bacteria, insects and humans alike create cities.
    • The engineering skills of honeybees are so sophisticated that a honeybee expert and a group of engineers used an algorithm inspired by honeybees to resolve internet traffic problems.
    • Bacteria are skilled engineers too.
    • Indeed, the entire planet was turned into a kind of bacterial internet three billion years ago.

Doctors and surgeons

    • Viruses invade bacteria and hijack their cellular machinery to make copies of themselves – a process which kills the bacteria.
    • Bacterial bodies produce enzymes that attack and kill virus DNA, a technique known as Crspr.
    • But ants from the species Megaponera analis, found in sub-Saharan Africa, are talented surgeons.
    • These ant surgeons were so effective that patients were spotted on the battlefield the next day.

Successful farmers

    • In turn, ambrosia beetles transport fungus spores in a pouch-like structure in their gut to tunnels bored into trees.
    • So, these tiny beings were all farmers millions of years before humans had even thought of it.
    • In so doing, this newly discovered wisdom could help us resolve the environmental crisis caused by our civilisation.

(“SMGH”), it has expanded reach for its Aureus raw materials in the European Union with a commercial export of purified cannabigerol (“CBG”) into the Czech Republic.

Key Points: 
  • (SMGH), it has expanded reach for its Aureus raw materials in the European Union with a commercial export of purified cannabigerol (CBG) into the Czech Republic.
  • The completed export into the Czech Republic marks the Companys first commercial export of CBG into the European Union and the twelfth (12th) market that the Aureus branded products has entered.
  • CBG is typically expressed in low amounts in common cultivars of cannabis, however, Avicanna has propagated proprietary cultivars that expresses exceptionally high amounts of the rare cannabinoid.
  • CBG also has the potential to be formulated across various delivery forms including topical and ingestible for a given therapeutic focus.

Penn Dental Medicine Study Explores New Strategy for Avoiding Childhood Tooth Decay

A few years ago, scientists from Penn Dental Medicine found that the dental plaque that gives rise to ECC is composed of both a bacterial species,Streptococcus mutans, and a fungus,Candida albicans.

Key Points: 
  • A few years ago, scientists from Penn Dental Medicine found that the dental plaque that gives rise to ECC is composed of both a bacterial species,Streptococcus mutans, and a fungus,Candida albicans.
  • The two form a sticky biofilm that becomes extremely difficult to displace from the tooth surface.
  • Now, a new study from the group offers a strategy for disrupting this biofilm by targeting the yeast-bacterial interactions.
  • "This offers us another tool for disrupting this virulent biofilm," says Geelsu Hwang , assistant professor at Penn Dental Medicine and senior author on the study, published in mBio .
