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!

The Good News

Carbohydrates are one of the body’s essential macronutrients (along with protein and fat). We use carbs to convert the food we eat into energy. How does this work? It’s a sophisticated process:

• Carbs break down into sugars as we digest them
• Sugars are absorbed into our bloodstream
• The pancreas releases insulin when blood sugar levels rise
• Insulin enables sugars to move from our blood to our cells
• Cells throughout the body use this sugar for energy.

Without the necessary amount of carbohydrates, our bodies lose a vital source of energy. So, why are carbs a dental concern?

The Bad News

Some foods immediately begin breaking down into sugars in the mouth. Sugars are a favorite food source for the oral bacteria that form plaque. They use this sugar to produce the acids that weaken our enamel and lead to cavities. And the more often we eat these foods, and the longer they remain in the mouth, the more damage our enamel suffers.

But there’s a silver lining! We can be healthier physically and get a jump on preventing damage from sugary treats by becoming more discriminating in our choice of carbs and timing our indulgences wisely.

Good Carb/Bad Carb

Unprocessed, complex carbohydrates are found in foods like whole-grain breads and cereals, legumes, and vegetables. They contain the vitamins, minerals, and fibers which are lost when foods are refined. They are composed of larger, more complex molecules, and so they break down gradually for sustained energy.

Some simple carbohydrates break down into sugars more quickly, but also offer important vitamins, minerals, and fiber. Fruits and dairy products, for example, are an important part of a balanced diet.

But some carbs are not pulling their nutritional weight. Refined sugars (think candies, desserts, and sodas) and refined starches (white bread and rice, potato chips, pastries) break down quickly into sugar in the mouth. Worse, many of these foods tend to stick around. Sticky sugars and sticky starches cling to our enamel and hide between the teeth and in the crevices of our molars. Not only do these treats provide a sugary feast for acid-producing bacteria, they take their time doing it!

So, What to Do?

If you have a diet filled with healthy carbs (whole grains, fruit and vegetables, legumes, dairy products), you’re already on the right track. Kudos! But does this mean no desserts? Ever?

No! We all need a cookie sometimes. But you can decrease the chance of enamel damage by interrupting the carbs to cavities cycle.

First, if you are indulging in a rich dessert or some salty chips, better to do it as part of a meal. When you eat a full meal, your body produces more saliva. Saliva not only helps wash away food particles, it also helps neutralize the acids that damage enamel.

Secondly, if you eat simple carbs and sugars all day, your mouth and teeth are being treated to acids all day. If you are going for a snack, there are many great options that don’t use refined sugars and starches. Think fruit smoothies (with a big dollop of vegetables) or whole-grain crackers with hard cheese instead of a can of soda and a bag of pretzels.

Carbs aren’t really bad, they’re just misunderstood. Talk to Drs. Rottschalk, Acker, and Froidcoeur at your next checkup at our Fairview Heights, IL office for ideas for the best carbohydrate choices for healthy metabolisms and healthy smiles!

Congratulations! Your pregnancy is a time of joy and excitement—and a time to take special care of yourself. You’ve discovered that pregnancy brings many physical changes, but it may still come as a surprise to learn that pregnancy hormones can affect your oral health as well. What should you look out for?

Gingivitis

Beginning in the second or third month of pregnancy, your gum tissue may show signs of gingivitis. Pregnancy hormones can cause an increase in the blood supply to your gums and affect the way your gums respond to plaque. These changes may lead to gums that are swollen, red and more likely to bleed upon brushing. This early form of gum disease should be treated as quickly as possible to avoid a more serious condition called periodontitis.

Periodontitis

Without treatment, the inflammation caused by gingivitis can increase. Periodontitis can lead to gums pulling away from the teeth, creating “pockets” that can be home to infection. These infections can lead to bone and tooth loss, so professional treatment is a must.

Pregnancy Granulomas

If you find a dark red swelling along the gumline or between two teeth, it might be a pregnancy granuloma. These granulomas are thought to be triggered by pregnancy hormones and may be a reaction to plaque or some other irritant. They often disappear once your baby is born and usually don’t cause any bother, but if you develop discomfort eating or speaking, your dentist might suggest removal.

You are looking for every way possible to provide your baby with the best start in life, so it is important to know that some studies have suggested a link between periodontal disease in pregnancy and complications such as pre-term delivery and low birth weight. Here are some important ways to maintain your oral health during pregnancy:

• Call Drs. Rottschalk, Acker, and Froidcoeur when you find out you are pregnant. We have suggestions for your dental care that you can use immediately.
• Keep to your regular schedule of dental examinations and cleanings at our Fairview Heights, IL office. If you find your gums beginning to show signs of gingivitis, call our office for an appointment. You might need to have your teeth cleaned more often during your pregnancy to avoid plaque buildup.
• Maintain your daily dental hygiene. Be sure to carefully brush along the gumline to discourage plaque formation. If you have not switched to a soft bristle toothbrush, now is the time! Talk to us about possible rinses or other at-home treatments.
• See a periodontist if needed for more serious gum problems.

Your pregnancy is a time to treat yourself and your baby with care. Talk to our office as soon as you find out you are pregnant. Making your dental health a priority can bring rewards both now and in the future, and we welcome the opportunity to suggest the best possible ways to care for yourself and your baby!

We’re all trying to find a healthy balance in our lives. Balancing work and home life. Eating a well-balanced diet. Balancing our budgets. Maintaining the right pH balance in our mouths for better dental health. Wait, what was that last one?

You probably don’t spend a lot of time thinking about your pH levels, but if your oral pH is out of balance it can affect the health of your teeth.

What do we mean by pH levels? In biology and chemistry, the pH scale is a tool used to measure the concentration of hydrogen (H⁺) ions and hydroxide (OH⁻) ions in a solution.  

The higher the concentration of hydrogen atoms, the more acidic a solution. The higher the concentration of hydroxide ions, the more alkaline. The pH scale goes from 0 to 14, with the most acidic reading possible rating a 0, and the most alkaline, a 14.

You don’t have to be a biochemist to use the information provided by pH samples. We use pH readings to discover the ideal acid/alkaline conditions in many everyday applications. Azaleas grow best in very acidic soil. Swimming pools should be just a bit alkaline. Brewers test pH throughout the beer-making process for optimal fermentation—and taste.

When it comes to saliva, a neutral pH range of around 6.2 to 7.6 is generally considered normal. High alkalinity in saliva is rare. High acidity levels? Unfortunately, much more common. And an acidic environment has real-world consequences for teeth.

Plaque contains bacteria, which produce acids. Calcium and phosphate, the minerals that help make enamel the strongest substance in the body, are leached out by these acids. The weak spots left behind make enamel vulnerable to further erosion and, eventually, decay. When saliva has a normal, neutral pH, it helps neutralize plaque acids to reduce the risk of cavities.

But it’s not just bacteria that expose our teeth to acidic conditions—we do it ourselves with our choice of food and drink.

Acidic foods can directly lower the pH level in saliva. Lemon juice, for example, has a pH between 2 and 3. Red wine has a pH between 3 and 4. Blueberries? Around a 3.2. When the pH level in saliva becomes 5.5 or lower, the minerals in our teeth start to “demineralize,” or lose the minerals which keep enamel strong and intact—just the way enamel is demineralized by acids from plaque. This process is known as acid erosion.

Many of our favorite foods are acidic to some degree. Citrus and other fruits, pickled foods, vinegar, wine, coffee, tea—all of them can lower the optimal pH level of saliva. And sports drinks, energy drinks, and sodas? Check the labels and you’ll often find citric acid, phosphoric acid, and/or carbonation, all of which combine to create extremely erosive conditions.

So, no more soda? Or fruit? No. You don’t have to give up acidic foods altogether for healthy teeth. True, you won’t give up much eliminating soda from your diet. But fruits, vegetables, dairy foods, and meats are the source of essential vitamins, minerals, and proteins, and many of these healthy food choices have an acidic pH. How to eat nutritiously while protecting your enamel? Again, it’s a balancing act.

• Enjoy acidic foods sparingly, or as part of a meal. Saliva can neutralize acids more effectively when they aren’t washing over your teeth all through the day.
• Use a straw when you drink something with a low pH to reduce your enamel’s exposure to acids.
• Balance high-acid foods with low-acid choices to help neutralize the acids in your diet. Add a banana to your blueberry smoothie. Pair your wine with some cheese.
• Rinse with water after eating or drinking. When it comes to balanced pH, pure water is a 7.0 on the scale, a perfect neutral.
• Chew sugarless gum to increase saliva production.
• Use fluoride toothpaste—it not only helps prevent cavities, it helps remineralize teeth.

Even with your best efforts, acid erosion can be a problem. You might be experiencing enamel damage if you notice any of these symptoms:

• Tooth pain or sensitivity.
• Teeth that appear discolored. This happens as the whiter enamel thins, revealing the yellowish dentin underneath.
• Changes in the shape of your enamel—your teeth become rounded or have little dents or pits, known as cupping.
• White spots on your teeth, which could be a sign of demineralization.

If you think you could be suffering from enamel erosion, it’s a good idea to talk to Drs. Rottschalk, Acker, and Froidcoeur when you visit our Fairview Heights, IL office. We can diagnose conditions causing acid erosion, treat you if enamel damage has occurred, and offer suggestions for diet and eating habits to make sure your oral pH—and your dental health—is always in balance.
