No one likes going to the dentist, but youshould all go every year. Because really, do you want to risk an infection in the biggesthole in your headé! Hey guys, Amy talking the joys of oral hygienewith you on DNews today! As many as 700 types of bacteria can livein our mouths, though most people only host between 34 and 72 varieties. Some of thesebacteria are innocuous, others known as probiotics actually help us digest food. There are evenbacterial strains that protect our teeth and gums. But there are some bad bacteria livingin your mouth as well. One is called streptococcus mutans. This bacteriafeeds on the sugars and starches you eat,
producing enameleroding acids as a byproduct,which can lead to tooth decay. Another bad bacteria is porphyromonas gingivalis, whichis linked to periodontitis, a serious and progressive disease that affects the softtissue and the alveolar bone that support the teeth causing tooth pain and in some casestooth loss. For most of us, our main dental issue willbe plaque, the film that builds up on your teeth and contains the bacteria that producesenameldestroying acids. Regular cleanings get rid of plaque, but if you don't cleanthe plaque from your teeth it hardens into tartar, which can get below your gums, causinginflammation and infection. That can open
a pathway into your bloodstream. Once thatbacteria is in your blood, it can get anywhere. The first place that bacteriafilled bloodcould go is your heart where there is some evidence that it can lead to atherosclerosis,or a hardening of the arteries caused by plaque, though this is a different kind of plaquethan you'd find on your teeth. The plaque in your arteries is made of cholesterol, fattysubstances, cellular waste products, calcium and a clotting agent called fibrin. It buildsup and thickens the walls of the arteries, constricting blood flow and increasing riskof a heart attack. Clogged or blocked arteries can also restrict blood flow to the brain,increasing risk of stroke.
A recent single study in Osaka, Japan,found that a quarter of stroke victims had a bacteria called cnmpositive S. mutans intheir saliva. The researchers acknowledged that it's a rare bacteria only 10 percentof people have, but it's still enough to reinforce the link between the oral bacteriumand stroke. And mouth bacteria can even follow a pathto your brain, increasing risk of dementia. A 2013 study from the University of CentralLancashire found a correlation between the bacteria commonly associated with gingivitisand an immune response that may kill neurons. This could ultimately change the brain ina way consistent with Alzheimer's disease.
And, if that weren't bad enough, letting bacteriaform colonies in your mouth can also lead to lung infections, but not through the bloodstreamâ€¦Instead you literally breathe oral microbes into your lungs, where it can infect and spread. And your oral health doesn't just impactyour body health, it can be a good indicator of your overall health. For example: gum diseasecan be a sign of diabetes, painful mucosal lesions are more common in people who areHIV positive, and tooth weakness or loss can be a sign of osteoporosis. So it should be said that this is a huge â€œmoreresearch is neededâ€� topic since most studies
have small sample sizes and need followupwork. And experts somewhat begrudgingly admit that we just don't know yet whether treatinggum disease can reduce the risk of heart attack, stroke, or dementia. But, really, do you needmore motivation for keeping up with dental visits than maintaining good teeth for chewingéFloss! Brush! And above all: go to the dentist!

Cold vs Flu Whats The Difference
This episode of DNews is brought to you byHARRY'S. So, it's cold and flu season. That sucks.But whenever I feel crappy, I can't tell if I've got the cold, or the flu does it matteréWhat's the differenceé! When I get a cough, or a headache or whateverfor a few days, I always assume it will go away, or that I just have a coldâ€¦ but sometimesâ€¦it's the FLU! Even though the medicine says its for both the cold and the flu, they'reentirely different viruses. The common cold is caused by over 200 different viruses! Coronaviruses,rhinoviruses, metapneumoviruses, enteroviruses and parainfluenza viruses all make the shortlist; but they really are all different. This
is why we can't quot;curequot; the common cold. Theflu, on the other hand, is caused by influenza viruses. These respiratory viruses invadethe body and set up shop and cause very similar symptoms, because the human body only hasso many ways to fight. When your body is invaded by a virus, chancesare you'll get the same symptoms every time, dry or sore throat, coughing and sneezing,mild fever, congestion and maybe a headache. Pretty standard stuff. If it's REALLY bad,you'll get aches and pains and exhaustion too. This happens because your body is spendingresources fighting off the viral infection. In general, flu is worse than the common cold,the fever is higher, the aches and level of
exhaustion are more pronounced, and the coughcan be more intense. While there's almost no way to tell the difference between thetwo infectionsâ€¦ colds tend to produce a fever less than 101 (38C), affects the throatand cause a runny nose. The flu, affects the lungs and the joints so you're likely tofeel more achy than leaky. Telling the difference is one thing, but onceyou're infected you only have a couple days to get treatment. After the first 48 hours,the infection has usually stopped multiplying and is wreaking havoc on the body instead.Regardless, once symptoms start for viral infections, there's no simple cure. AntibioticsWILL NOT HELP, because they fight BACTERIA
not VIRUSES. Taking an antibacterial drugduring a viral infection is pointless. In fact, a lot of the remedies for colds andthe flu aren't really based onâ€¦ well science. Many people take vitamin C like it's goingout of style, but a study from the University of Alberta looked at results and found there'sreally no evidence that it helps. Results suggest it MIGHT help with marathon runnerswho have compromised immune systems due to exhaustion, but even then it's a minor help.I like to take zinc when I'm starting to feel ill, and science DOES support that. Zinc isused by human immune cells as a catalyst, so when you boost the amount of zinc yourimmune cells can protect the body a bit better,
but too much can damage it so don't overmedicate. In the end, a cold will persist for 10 days,while some flu symptoms will persist for three weeks; long after the influenza virus hasbeen eradicated. If you REALLY want to avoid getting sick, get a flu vaccination. Only30 percent of surveyed adults get vaccinated year over year. Flu vaccines are made everyyear by specialists who use massive datasets to predict which influenza viruses will dominatethis season see, there's more than one mutation, and they vie for power and bodiesto infect. The 2014 flu vaccine will protect against Influenza A H1N1 and H3N2, as wellas a couple influenza B viruses. You might
recognize H1N1, we're still seeing that leftover from 2009's unexpected flu epidemic! Crazy righté So yes, there IS a difference between coldsand flu, but if you catch one of the over 200 viruses that cause these crappy feelingsthe best way to handle it is to drink fluids and help keep yourself hydrated and rest.If you minimize nutritional strain on your immune system by enjoying warm chicken soupand let your immune system do it's work, you'll be fine. Empathy can also help, studies haveshown people who have families or even an empathetic recover faster than thosewho don't so help out a friend if they're
