Has your mom ever told you to not spit out your saliva or to stop drooling? She may have had a point
What Does Saliva do for Your Teeth?
So is saliva harmful
The proof is in the spit
Erica Shapiro Frenkel, of Harvard University, and principal investigator Katharina Ribbeck, a professor at the Massachusetts Institute of Technology, both in Cambridge, MA, report their findings in the journal Applied and Environmental Microbiology. Frenkel says their findings suggest boosting the body’s natural
Watch the biofilms
The researchers found that salivary mucins do not alter levels
A biofilm is a densely packed community of microbes that grow on surfaces and surround themselves with sticky polymers that they secrete. Frenkel also points out that the oral microbiome – the collection of friendly bacteria in the mouth – is better preserved when naturally present species are not killed. “The ideal situation,” she adds, “is to simply attenuate bacterial virulence.”
As the bacterium grows under the protection of the biofilm, organic acid byproducts of its metabolism attack the tooth enamel, causing cavities. For their study, the researchers focused on how the salivary mucin MUC5B affects the ability of S.mutans to attach to teeth and form a biofilm. These are the two key steps necessary for cavities to form, Frenkel explains.
The investigation grew out of previous work looking at gastric mucins in pigs that protected against lung pathogens. The researchers wondered if salivary mucins might also play a protective role. Frenkel says common diseases like cystic fibrosis, ulcerative colitis and asthma have been linked to problems with mucin production.
“There is increasing evidence that mucins aren’t just part of the mucus for structure or physical protection, but that they play an active role in protecting the host from pathogens and maintaining a healthy microbial environment,” she adds. Prof. Ribbeck says this kind of research is important because it changes scientists’ views on host-microbe interactions:
“It is generating a paradigm shift from the textbook view of mucus as a simple catchall filter for particles, towards the understanding that mucus is a sophisticated bioactive material with powerful abilities to manipulate microbial behavior.” Meanwhile, Medical News Today recently learned that Roman Britons had less gum disease than modern Britons. The surprising discovery provides further evidence that modern habits like smoking can be damaging to oral health.
Saliva’s Job in Your Mouth
