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. Paul Pasternack, Chara Pasternack, and Christine Biondi know how your experiments turned out the next time you visit our Vorhees office!

Drs. Paul Pasternack, Chara Pasternack, and Christine Biondi and our team at Pasternack Pediatric Dental specialize in pediatric dentistry, and we understand that children can be frightened of things they do not understand. This anxiety is often heightened by an unpleasant dental experience or stories they hear from classmates. We have many methods at our Vorhees office to make your child’s dental visit pleasant and anxiety-free.

Listening

The first thing Drs. Paul Pasternack, Chara Pasternack, and Christine Biondi and our team do is talk to your child, listen to any concerns he or she may have, and take the time to explain the dental work that will be done. Often children will lose their fears by simply understanding what is happening and why. In addition, you are welcome to be in the room with your child during exams and treatments. When a child is able to see that the parent is relaxed, this is more conducive to the child’s relaxation.

Relaxation

When you arrive at Pasternack Pediatric Dental, let your child to play with the toys we provide. This starts the visit in a positive manner. Taking your child’s mind off the exam is useful. While your child is undergoing an examination or procedure, listening to music or watching a video can support a sense of relaxation. When children understand that we care, their anxiety levels are reduced.

Sedation

Nitrous oxide is a sedation technique commonly used to reduce anxiety and alleviate any pain. It is beneficial partly because the effects wear off quickly. Topical pain relievers can also be useful for children with sensitive teeth, and this will eliminate discomfort.

Deeper sedation is useful for complex dental issues, extreme anxiety, or a fear of needles. A liquid or tablet sedative can be given before your child’s appointment. This type of sedation is also helpful for children with a fear of the masks used for nitrous oxide.

We welcome you and your child to discuss any concerns that you have regarding his or her dental appointment. We want your child to be free from anxiety about visiting Drs. Paul Pasternack, Chara Pasternack, and Christine Biondi. The earlier your child’s fears are addressed, the less likely the fear will carry into adulthood.

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
