Rethink Your Drink

 As summertime temperatures are going up, the California Dental Association is encouraging the public to “rethink your drink” before downing a sugary beverage to quench thirst. 

While the media often focuses on the risks of obesity and diabetes, it’s important to realize that drinking sugar-filled sodas, sports drinks or juices can contribute to tooth decay and dental pain.
According to the California Center for Public Health Advocacy, the average American consumes 50 gallons of soda and other sweetened beverages each year.

 What’s more, statistics from the Centers for Disease Control and Prevention show more than 19 percent of children ages 2 to 19 have untreated cavities.

According to the CDA, bacteria feed on what you eat and drink, especially sugars, and this creates acid that can break down the tooth’s outer surface and dissolve the valuable minerals that protect teeth from decay.



“Sipping sugary drinks gives bacteria in the mouth more power to create acid that weakens tooth enamel and causes cavities,” said CDA President-elect Lindsay Robinson, DDS. “In addition, sports drinks pose many of the same risks as other sugar-loaded beverages, such as irreversible dental erosion, and should not be substituted for water.”



CDA urges people to swap out sugar-laden drinks for a glass of milk or water this summer.


“Water contains no sugar, no acids and no calories, so your teeth, and your body, will benefit,” said Robinson. “Water also helps keep gums hydrated and rinses away food particles that would otherwise remain in the mouth promoting bacterial growth that causes decay.”



Most importantly, protect teeth throughout the year by brushing for two minutes, two times a day with fluoride toothpaste, flossing regularly and visiting a dentist for a complete dental checkup on a regular basis.

Equip Yourself With The Best Weapon For Success: Knowledge

Take an online college class at no cost via Coursera (https://www.coursera.org/)




PHILADELPHIA –- The University of Pennsylvania will join Princeton University, the University of Michigan, the University of California, Berkeley and Stanford University in partnering with Coursera, an online education platform, to make Web-based courses available free and to improve teaching on campuses.

The Coursera education platform is the first to host content from multiple world-renowned universities at one online destination. These courses include video lectures with interactive quizzes, mastery-building interactive assignments and collaborative online forums.

Penn faculty will provide courses in medicine, business, music, literature, mathematics and computer science, among others.

"Penn is delighted to participate in this innovative collaboration that will make high-quality learning opportunities available to millions of people around the world," Penn President Amy Gutmann said. "Expanding access to higher education both nationally and globally remains one of our most critical responsibilities. This initiative provides an invaluable opportunity for anyone who has the motivation and preparation to partake of a world-class education."

With the capacity to reach millions of people at once, Web-based courses are pioneering a new model for higher learning, one that potentially gives everyone in the world access to a top-level educational experience. With an innovative design inspired by educational research on effective learning, the Coursera platform creates an interactive learning experience for the participating universities’ course offerings. Recorded video lectures contain frequent quizzes that reinforce concept retention, as well as deeper assignments that test students’ understanding and build mastery of the material. The Coursera platform also offers community forums that encourage students to participate actively with classmates from around the world.

Coursera was founded in the fall of 2011 by Daphne Koller and Andrew Ng, Stanford computer science professors. It builds on the technology they helped develop that was used to host Stanford’s free online classes. These classes were an instant success, receiving more than 350,000 enrollments across 172 different countries. Seven courses from Stanford and the University of California, Berkeley have been running for several weeks, and additional courses will launch later this week and through late summer.

During the next few months, new online courses across a range of disciplines will continue to be added to the online platform, from current university partners as well as other top-tier educational institutions.

Flu Virus: How long do cold and flu virus stay alive after the sneeze


It varies, depending partly on where the germ-laden droplets fall. Experiments with specific cold and flu germs have shown potential survival times ranging from a few minutes to 48 hours or more. How long such germs remain capable of infecting you in day-to-day life is harder to say.

According to Dr. Steckelberg of the Mayo Clinic, Researchers have repeatedly found that cold and flu germs generally remain active longer on stainless steel, plastic and similar hard surfaces than on fabric and other soft surfaces. On any surface, though, flu viruses seem to live longer than cold viruses do. Other factors, such as the amount of virus deposited on a surface and the temperature and humidity of the environment, also have effects on how long cold and flu germs stay active outside the body.

The rapid spread of some colds and types of flu certainly suggests that indirect transmission is common. You might, for example, catch the flu or a cold from rubbing your nose after handling an object an infected person christened with a sneeze a few moments ago. That said, it's important to note that cold and flu viruses primarily spread when an uninfected person has direct contact — a handshake, for example — with an infected person.

This is the height of flu season. The best way to avoid becoming infected with a cold or flu is to wash your hands frequently with soap and water or with an alcohol-based sanitizer. Also, try to notice and stop yourself when you're about to rub your eyes or nose or bite your nails. And — most important — get a seasonal flu vaccine every year and the H1N1 (swine) flu vaccine when it's available. Some people will always be careless about spreading their germs, but you don't have to catch them.

Gummy Tummy?


At our OrthoWorks offices, we know the rumors going around—mostly among young people—that once you swallow a piece of chewing gum it will stake a claim and take up residency in your stomach for at least seven years! We really hate to take all the fun out of the mystery, but the truth is that chewing gum, when swallowed, will enter the stomach and move through the digestive system just like any other piece of food and leave the body long before seven years! So, if you ever have accidentally swallowed a piece of gum, there is no need to worry!

This being said, gum does not have any dietary benefits, so while it’s not harmful to swallow, you still want to avoid swallowing it. If you are a gum-chewer, make sure you chew sugarless gum, because gum with sugar can lead to cavities. Sugarless gum still has the same amount of flavor, but with less cavity causing ingredients. You see, when the bacterium in your mouth breaks down sugar, what’s left behind is acid. This acid eats away at the enamel coating of your teeth, causing holes that we call cavities. Cavities can lead to other long term mouth problems if they are not treated in time, so it is best to try and avoid overexposing your teeth to too many harmful substances!

Happy (sugar-free) gum chewing!

What is Obstructive Sleep Apnea


Obstructive sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts during sleep. Several types of sleep apnea exist, but the most common type is obstructive sleep apnea, which occurs when your throat muscles intermittently relax and block your airway during sleep. The most noticeable sign of obstructive sleep apnea is snoring.

Anyone can develop obstructive sleep apnea, although it most commonly affects middle-aged and older adults and people who are overweight. Obstructive sleep apnea treatment may involve using a device to keep your airway open or using a mouthpiece to thrust your jaw forward during sleep. Some undergo a procedure to change the structure of their nose, mouth or throat.

What are the symtoms?

Signs and symptoms of obstructive sleep apnea include:

Excessive daytime sleepiness (hypersomnia)
Loud snoring
Observed episodes of breathing cessation during sleep
Abrupt awakenings accompanied by shortness of breath
Awakening with a dry mouth or sore throat
Morning headache
Difficulty staying asleep (insomnia)
Difficult-to-control high blood pressure

When to see a doctor?

Consult a medical professional if you experience, or if your partner observes, the following:

Snoring loud enough to disturb your sleep or that of others
Shortness of breath that awakens you from sleep
Intermittent pauses in your breathing during sleep
Excessive daytime drowsiness, which may cause you to fall asleep while you're working, watching television or even driving a vehicle
Many people don't think of snoring as a sign of something potentially serious, and not everyone who snores has obstructive sleep apnea. But be sure to talk to your doctor if you experience loud snoring, especially snoring that's punctuated by periods of silence. With obstructive sleep apnea, snoring typically is loudest when you sleep on your back, and it quiets when you turn on your side.

Ask your doctor about any sleep problem that leaves you chronically fatigued, sleepy and irritable. Excessive daytime drowsiness (hypersomnia) may be due to other disorders, such as narcolepsy.

What Causes Tooth Sensitivity?


What is it?

Tooth sensitivity is something that affects a number of people. It is often caused by eating or drinking something hot, cold, sweet or acidic. Under normal conditions, the underlying dentin of the tooth (the layer that immediately surrounds the nerve) is covered by the enamel in the tooth crown, and the gums that surround the tooth. Over time, the enamel covering can get thinner, thus providing less protection. The gums can also recede over time, exposing the underlying root surface dentin.

The dentin contains a large numbers of pores or tubes that run from the outside of the tooth to the nerve in the center. When the dentin is exposed, these tubes can be stimulated by changes in temperature or certain foods.

What causes it?

Exposure of the dentin can occur due to a number of factors. Some of the more common reasons are:

Gum recession due to age or improper tooth brushing. Acidic beverages (such as soda) that cause enamel erosion and dentin exposure.
Tooth grinding. This may actually cause most or all of the teeth to feel sensitive.
Brushing with a very abrasive toothpaste, brushing incorrectly and/or brushing more than three times a day could result in a loss of enamel.
Gum disease, which can result in gum recession
A chipped or fractured tooth may expose the dentin
In addition, some dental treatments can cause sensitivity. Treatments such as such as teeth whitening, professional dental cleanings, having braces put on or getting a filling placed have been known to cause sensitivity during or after the procedure.

What can I do about it?

The first step in doing something about dental sensitivity is to find out what the cause is – a dental professional can help you with this. If the sensitivity is due to exposed dentin, there are a number of steps you can take, as can your dental professional, to help reduce the sensitivity. These can include:

Using a very soft bristle tooth brush
Brushing correctly to help prevent abrasion of the enamel and recession of the gums
Using a toothpaste specially formulated to help reduce sensitivity.
Your dentist can apply a fluoride varnish on the sensitive areas to help strengthen the tooth. He or she can prescribe a high fluoride tooth paste or gel to use every day. The fluoride can help to plug in the pores in your dentin thus making your teeth less sensitive. Or your dentist can place a dental filling to build up the areas that have lost enamel.
In the end, whether you need an in-office procedure or over-the-counter products, the most important step is to see a dental professional so that he or she can determine the cause of the tooth sensitivity and help you find a solution that will work. If you have further questions about tooth sensitivity, please feel free to call our office, OrthoWorks, at 1 888 BRACES-2 and we would be glad to answer your questions for you.
