Let’s talk about the science of our teeth for a moment. Our enamel has a very high mineral content, making it extremely strong.  In fact, enamel just happens to be the hardest substance in our bodies.  But, unfortunately, it is not indestructible! Certain foods we eat can actually damage the surface of our teeth. Some simple and entertaining experiments can show children how our teeth can be affected by things we eat and drink, and how we can help protect them.

If you have a science-minded student at home, there are many activities you can do together, using educational websites, common household products and lots and lots of eggs. (Why eggs? Eggshells are a great substitute for teeth in these experiments. Not only are they various shades of white--like our own teeth, they are also calcium-rich—like our own teeth.) You can find any number of experiments using uncooked eggs, hardboiled eggs, whole shells with the contents blown out, or eggshells alone, so you can find just the right activity for whichever egg treatment works best for you.

Examine Enamel Erosion

One of the ways we protect our teeth is with healthy eating. The bacteria in plaque use the sugars and starches in our foods to produce acids. These acids are the substances that break down the minerals in our enamel and leave the enamel weaker. Weaker enamel is more easily attacked by bacteria and acids, which leads to cavities.

With eggs or eggshells and some carefully selected food products, you can see just how acidity affects teeth. Different websites suggest a variety of acidic liquids to dunk your eggs in, such as vinegar, soda, or citrus juices, so it’s easy to find an experiment that works with your pantry. Always use a plain water sample when you submerge eggs or shells to act as a control to measure differences against. How do the egg shells soaked in acidic liquids differ from those in plain water? It’s also fun to add simple sugar water as a test liquid to see what happens. Is it sugar or acid that causes more damage? And why might that be?

The Fluoride Fix

Fluoride is well known as a mineral that protects the structure of our teeth and helps prevent cavities. And there are actually experiments out there to test the protection fluoride provides using your egg stand-ins.

In some experiments, a hardboiled egg is coated with fluoride toothpaste or rinse for a specific amount of time and then dunked into vinegar. An untreated egg also gets a vinegar bath. You are asked to observe what is happening to each egg as it sits in its vinegar bath—are there bubbles on one egg and not the other? What do the bubbles mean? Other experiments require longer exposure to fluoride and then to vinegar—what happens to the shells of the treated and untreated eggs? What could this mean for our teeth?

Staining Studies

Our diet can do more than help create cavities. Enamel is very strong, but it is not stain-proof! Dark colored foods and drinks can make our teeth appear darker or more yellow. (And teeth that have suffered enamel erosion can pick up stains more easily.) How does food affect the brightness of our smiles?

If this question interests you, find experiments that use favorite beverages as a soak for your eggs. Choose liquids with a range of color, such as coffee, soda, and apple juice. Or choose an experiment that uses different varieties of soft drinks. Will foods the same color cause the same amount of discoloration in your egg volunteers? Do you want shorter or longer soaks in each liquid? Do you want to make use of a recycled toothbrush to see if brushing that discolored shell makes a difference? With toothpaste or without?

Even though these activities are designed for older children, they still require adult supervision. You can find detailed instructions for any of these experiments at many science and educational sites online. With some household supplies, plenty of extra cups, and a quantity of eggs, you and your child can demonstrate some of the basic effects our food choices have on the health and appearance of our teeth. It’s a wonderful way to promote healthy eating and brushing habits, scientific curiosity, and shared experiences!

Don’t forget to let Drs. Nasrin Azimzadeh, Kristina Djukic, and Tabasam Akbar know how your experiments turned out the next time you visit our Chicago office!

You may have heard how important calcium is to your body. Over 99% of the calcium in our bodies is used to form teeth and bones, providing strength and structure to the hardest parts of the body. But that’s not the only task on the calcium to-do list. Calcium is also necessary for:

• muscles to work
• nerves to carry messages
• blood to deliver nutrients and oxygen
• the release of hormones

When we don’t get enough calcium in our diets, our bodies start to draw the calcium they need for these critical functions from our teeth and bones. Over time, a severe calcium deficiency can lead to teeth that are brittle, or more vulnerable to decay, or loose due to weakened bone density in the jaw.

We can get the calcium we need from a balanced diet. Dairy products are our most common source of calcium, and several servings of milk, cheese, or yogurt each day supply most of our needs. If dairy’s not on your menu, though, you can get calcium from other foods like broccoli, kale, collard greens, canned salmon, or sardines. Because calcium is so essential to our health, many foods are fortified with it, including fortified juices, bread, cereals—even tofu!

But there’s a snag here, and it’s a big one. We can’t really benefit from our careful consumption of calcium without the help of vitamin D. If calcium is the doorway to strong teeth and bones, vitamin D is the key that unlocks all of calcium’s benefits.

Without enough vitamin D, our bodies can’t absorb and make use of calcium. However, getting enough of this essential vitamin can be a problem. While we can get most of the vitamins we need from a balanced diet, there aren’t a lot of foods which are naturally rich in vitamin D.

So, how do we get this vital vitamin? The original option comes from nature.

• Sunlight

Vitamin D is called “the sunshine vitamin” because of the unique chemical reaction that creates it. When the ultraviolet B rays of the sun reach special cells in our skin, they convert cholesterol in these cells to a basic form of vitamin D. These vitamin molecules travel through the body, picking up hydrogen and oxygen molecules in the liver and kidneys to become active vitamin D.

Since sunlight exposure is easy, available, and free, it seems like a simple solution to getting the vitamin D we need.

But we’ve understandably moved away from the days of basking in the sun for hours at a time. Over-exposure to UV rays damages the skin, causing premature aging and, worse, a much greater risk of skin cancer. If you enjoy time in the sun, talk to your doctor about safe sun exposure, which can depend on the part of the country you live in, the time of year, and your individual skin type.

And, if you need to avoid sun exposure, there are other opportunities for getting the vitamin D you need.

• Diet

While there aren’t a lot of foods which are naturally rich in vitamin D, there are still a few options on the menu. Oily fish like salmon, tuna, and herring—and old-fashioned cod liver oil—are good sources of the vitamin. But most of us don’t live on a strict fish diet!

Instead, we can get the vitamin D we need from fortified foods. Vitamin D is commonly added to cow’s milk, soy milk, orange juice, and cereals to make sure the calcium in our diet is working effectively to keep our teeth and bones strong. Check out nutritional labels to discover whether your favorite grocery products contain vitamin D.

• Supplements

For hundreds of years, people who lived in climates and cities without a lot of sunshine suffered from the effects of vitamin D deficiency. Diseases like rickets, where the teeth and bones don’t form properly, were common in children. Adults who couldn’t absorb enough calcium suffered from weak teeth and bones.

Today, depending on age, allergies to sun or food products, dietary choices, and health conditions, some people are still at risk for vitamin D deficiency. If you’ve been diagnosed with this deficiency, your doctor might recommend a vitamin D supplement. (It’s important to take any supplement as directed, because taking too much vitamin D can be harmful, too.)

So, which form of vitamin D is best? Fortified foods? Supplements? Or is it that radiant original source—the sun? No need to worry. With any form of vitamin D, you’re getting the key you need to unlock the benefits of the calcium in your diet—benefits which make healthy teeth and bones possible.

If you have any concerns, talk to Drs. Nasrin Azimzadeh, Kristina Djukic, and Tabasam Akbar at our Chicago office about whether you’re getting the vitamin D you need. Your sunny smile will thank you!

What is oral cancer?

April is Oral Cancer Awareness Month. If you have been putting off a visit to our Chicago office, now is an excellent time to schedule one. Regular visits to South & West Loop Dental can be the first line of defense against oral cancer, by identifying early warning signs of the disease, or helping you with preventive care tips to lower your chances of developing it.

Oral Cancer Rates in America

Nearly 40,000 people in the U.S. will be diagnosed with oral cancer this year, and more than 8,000 die every year from this disease. It is a devastating illness: most people who are diagnosed with it do not live more than five years beyond their diagnosis. Oral cancer has a higher death rate than many other common cancers, including cervical cancer, testicular cancer, Hodgkin’s lymphoma, and thyroid or skin cancers. The high death rate results from the fact that most oral cancers go undiagnosed until the disease is well advanced and has spread to another part of the body—most often, the lymph nodes in the neck.

What causes oral cancer?

While there is no way to predict exactly which individuals will get oral cancer, there are some potential causes you should know about—because in some cases, you can minimize these risk factors.

• Age (most patients diagnosed with oral cancer are over the age of 40)
• Tobacco use, either from cigarettes or smokeless chewing tobacco
• Excessive alcohol consumption (especially in combination with tobacco use)
• Persistent viral infections, such as HPV16
• A diet low in fruits and vegetables

In addition, oral cancer tends to occur at a rate six times greater in men than in women, and more often for African Americans than other ethnic groups. No genetic links have been identified to explain the higher incidence in these populations, so lifestyle choices remain the likeliest cause.

Oral Cancer Treatments

Once a diagnosis has been made, treatment of oral cancer usually involves a multi-disciplinary team that includes surgeons, oncologists, dentists, nutritionists, and rehabilitation and restorative specialists. Our team will decide on the best approach for each patient, depending on the risk factors and how far the cancer has progressed. The strategy will be different in every case. Some of the most common methods include chemotherapy, radiation, and potential surgery.

Finding out you have cancer can be devastating news. If you are concerned that you might be at risk for developing oral cancer, talk to us about screenings and other things you can do to reduce your risk.

Sometimes the line between fact and fiction is easily blurred. This is certainly the case when it comes to dentistry, where myths and misconceptions abound. In a bid to put an end to health hoaxes, here are five dental myths to chew over.

Sugar Is the Number One Culprit of Tooth Decay

Sugar will rot your teeth. If you’re a parent, chances are you tell your children this every time they ask for something sweet. And chances are your parents told you the same thing. There’s no denying that sugar leads to cavity formation, but it's not the number one culprit of tooth decay. Sugar adds fuel to the fire, but it doesn’t light the match.

Going to the Dentist Is a Painful Experience

There are people who don’t go to the dentist because they think it’s going to be a painful experience. It’s time to put this myth to rest. New dental technology, developments in anesthetics and analgesics, and more conservative dental procedures have made visits to our Chicago office a more comfortable experience.

Bad Breath Means You’re Not Brushing

Poor dental hygiene can cause bad breath, but it’s not the only thing that will leave you looking for a breath mint. There are many factors that can cause bad breath, including illness, acid reflux, medication, and dehydration. In addition, sometimes what you eat or drink can give you bad breath no matter how many times you brush and floss. Next time you order a sub for lunch, skip the onions and garlic.

Bleaching Products Weaken Teeth

Gels, pastes, strips — there are all sorts of products available to make our pearly whites even whiter. If used according to the directions, bleaching products are harmless. They do not affect the health or strength of the teeth, only the color. At the same time, too much bleaching can cause temporary tooth sensitivity or irritated gums; the enamel, however, is not weakened.

You Will Know When You Have Tooth Decay

This is the type of false information that can lead to serious dental problems. There are no early symptoms of tooth decay. By the time you experience pain, your tooth decay has led to nerve damage, which means your decay is advanced and extensive. The only way to know if you have tooth decay —and to prevent it — is to visit Drs. Nasrin Azimzadeh, Kristina Djukic, and Tabasam Akbar twice a year for a checkup and cleaning.
