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!

Hand-foot-and-mouth disease, or HFMD, is a type of contagious viral illness that causes a rash in the mouth and on the hands and feet of infants and young children, and, while rare, adults. Characterized by sores in the mouth and a rash on the hands and feet, hand-foot-and-mouth disease is most commonly caused by a coxsackievirus, a bacterium that lives in the human digestive tract. HFMD can spread from person to person, typically via unwashed hands.

What are the symptoms of HFMD?

Symptoms of HFMD usually begin with a fever, sore throat, poor appetite, or general malaise. A couple of days after the fever starts, kids may develop painful sores in the mouth. A skin rash characterized by red spots may also develop, usually on the palms of your child’s hands and soles of their feet. It’s important to note some children may only experience a rash while others may only have mouth sores.

Is HFMD serious? Should we be concerned?

Usually not. Nearly all children infected recover anywhere between seven to ten days without medical treatment. Rarely, however, a child can develop viral meningitis and may need to be hospitalized. Other rare complications of HFMD can include encephalitis (brain inflammation), which can be fatal.

How can my child prevent HFMD?

There is no known vaccine to defend your child against HFMD. However, the risk of your child contracting the disease can be reduced by:

• Making sure your child washes his or her hands often
• Thoroughly cleaning objects and surfaces (these include doorknobs and toys)
• Making sure your child avoids close contact with those who are infected

We probably all remember sitting through history lessons during our schooling years. Revolutionary war heroes, English royals, and pop-culture icons filled the pages of our textbooks. Although you may recall a detail or two about their historical significance, how much do you know about their teeth?

Picture England in the mid 1500s. People wore frilly clothes as they hustled along the street, and talked about the latest import from the Indies: sugar. Wealthy Brits did not hesitate to indulge their sweet tooth, and it was no different for the monarch, Queen Elizabeth I.

The queen was especially fond of sweets, but not so fond of the dentist. Her teeth rotted; they turned black and gave off a foul odor. Eventually, Elizabeth lost so many teeth that people found it difficult to understand her when she spoke.

Flash forward to the Revolutionary-era colonies in the 1770s and we encounter the famous dentures of George Washington. They were not made of wood, but rather a combination of ivory and human teeth, some of which were his own pulled teeth and some he purchased from slaves.

Washington did not practice proper dental hygiene throughout his life. He began to suffer dental problems as early as age 24, when he had his first tooth pulled. By the time he was inaugurated in as the first president in 1789, he had only one tooth remaining in his mouth, which was pulled in 1796.

Washington’s dentures were made too wide and never quite fit his mouth properly. He complained that they were painful to wear and caused his jaw to protrude visibly outward.

If you’ve heard of Doc Holliday, you know him as the gun-toting, mustached criminal that ran the Wild West in the late 1800s. You might be surprised to learn that John Henry “Doc” Holliday actually had a career as a dentist.

He graduated from dental school in 1872 and began to practice in Griffin, Georgia. Holliday was later diagnosed with tuberculosis and his violent coughing fits during exams drove patients away. Jobless, he packed his bags for Texas and spent the rest of his days running from town to town as a criminal.

The Beatles brought pop music and British culture to their fans, as well as … teeth? In the mid-1960s, John Lennon had a molar removed that he presented as a gift to his housekeeper, Dorothy. Dorothy’s daughter was a huge fan of the Beatles and he thought she might like to a keepsake. Her family held onto the tooth until 2011, when they auctioned it off to a Canadian dentist for $31,000.

These historical figures had very different experiences with their teeth, but it’s safe to say a bit of extra brushing and flossing could’ve saved them a lot of trouble. Whether you’re queen, president, or an average citizen, it’s up to you to practice good dental hygiene!

Many people who are careful about brushing and flossing their teeth wonder how they still end up with cavities or tooth decay. Several factors affect wear and tear on tooth enamel. Diet is a major factor, with certain foods increasing the likelihood that your enamel will become discolored or decayed. Pay close attention to the foods you eat to keep your pearly whites looking healthy and clean.

What causes enamel damage?

Tooth enamel refers to the hard, semi-translucent, whitish part of the tooth that shows above your gums. The enamel is primarily composed of minerals that are strong but susceptible to highly acidic foods. When acid reacts with the minerals in enamel, it results in tooth decay. Strongly pigmented foods can also damage enamel by discoloring the surface of the tooth.

Foods that harm enamel

Acidic foods are the greatest source of enamel damage. To determine whether a food is acidic, look up its pH. Scientists use pH, on a one-to-seven scale, to define the relative acidity or alkalinity of a substance. Foods with low pH levels, between a one and three, are high in acidity and may damage your enamel. Foods with high pH levels, such as a six or seven, are far less likely to cause enamel harm.

So which foods should you avoid? Many fruits are high in acidity, including lemons, grapefruit, strawberries, grapes, and apples. The high sugar and acid content in soda makes it another huge contributor to enamel decay. Moderately acidic foods include pineapple, oranges, tomatoes, cottage cheese, maple syrup, yogurt, raisins, pickles, and honey. The foods that are least likely to cause enamel damage include milk, most cheeses, eggs, and water.

Beverages such as red wine and coffee also damage the enamel by discoloring it. Although stains do not necessarily undermine the integrity of your teeth, they can be unsightly.

What can I do to prevent enamel damage?

Fortunately, there are several measures you can take to prevent your enamel from discoloring or decaying. The easiest way to avoid decay is to steer clear of high-acidity foods. This may not always be possible, but eliminating sugary fruit juices and soda from your diet is a good start. Brushing your teeth after each meal and flossing frequently also preserves your enamel. Another good idea is to rinse your mouth with water or mouthwash after eating to wash away high-acidity particles.

Although enamel damage is common, it does not have to be an inevitable occurrence. Knowing the foods that harm your teeth gives you the tools to prevent discoloration and decay. With some easy preventive measures, your teeth will stay strong and white for years to come! Give us a call at Pediatric Dental Specialists of Central Oklahoma to learn more!
