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 Dr. Parulkar know how your experiments turned out the next time you visit our Lewis Center, OH office!

The dog days of summer are upon us, and what better time for Dr. Parulkar and our team to ask our patients about their summer!

Whether you visited our nation’s capital, went on a camping trip, or just stayed in Lewis Center, OH and relaxed, we want to know how you’re all spending your summer! Please feel free to share your summer plans and experiences with us below or on our Facebook page as summer rolls on!

School’s out and you’ve emptied your gym locker until next fall. But while you’re stowing away the football gear, the basketball warm-ups, the field hockey sticks, and all the other equipment you’ve collected over the school year (that’s where that other shoe went!), be sure to keep one item handy: your mouthguard.

Team and contact sports like football, basketball, and wrestling aren’t the only potential dental dangers. In fact, almost any sport or activity can be made safer when you use your mouthguard.  While you’re keeping active and fit in the summer months, remember to look out for your smile.

• Sports on wheels

Biking, skate boarding, rollerblading—it only takes one fall to make you realize that roads, sidewalks, and concrete are not ideal landing pads. If you do take a spill, using a mouthguard, along with your helmet, will help protect your teeth and jaw.

• Court sports

Handball and tennis are not what we consider contact sports, but an unexpected bounce from a ball, or a completely unexpected backhand from your partner, can lead to dental injuries. Ace your workout and wear a mouthguard.

• Water sports

A fall in the water can lead to a collision with your surfboard or water skis, and water polo often seems to be a game of stamina, accuracy and elbows. Wear your mouthguard on land and sea, and help reduce your chance of dental injury.

• Team sports

Anyone who has played summer league baseball, softball or soccer knows that occasional contact with other players is pretty much a given. Cushioning your head, mouth, and teeth with a mouthguard will not only protect you, but keep you in the game—and your teammates will appreciate that!

If you already use a mouthguard, keep up the good work! If you don’t, talk to Dr. Parulkar about the importance of protecting your smile with a mouthguard. There are ready-made options available at drug stores and sporting goods shops. These will provide protection to your mouth and teeth, but can sometimes be bulky and uncomfortable and should never be used with braces. If you would like a mouth protector that provides the best fit and comfort, or if you wear braces, we can customize a mouthguard in our Lewis Center, OH office that will be a perfect fit for your teeth and bite.

Whatever activity you choose, play it smart! Don’t gear up without your mouthguard, and you’ll greet next year’s classes energized, fit, and sporting a beautiful smile!

Happy Independence Day from Dr. Parulkar and team! The Fourth of July celebrations in America may have changed a lot over the years, but there is no doubt that we Americans love to celebrate the anniversary of our country's independence! Today we're devoting the Delaware Pediatric Dentistry blog to some fun facts about the Fourth!

• My, how we have grown! This year the United States Census Bureau estimates that our country has 313.9 million residents celebrating the Fourth of July this year, but back in 1776 there were just 2.5 million members of the country.
• Our country loves to show how proud that we are of our independence. Did you know that there are 31 United States places with the word “Liberty” in their names? The state of Iowa actually has four towns with the word Liberty in the name: Libertyville, New Liberty, North Liberty, and West Liberty.
• The United States loves Fourth of July food! It is expected that around 150 million hot dogs are eaten on the Fourth each year. One of the Fourth's most popular sides, potato salad, goes just perfectly with the hotdogs and hamburgers that are standard Fourth of July fare. Some people choose potato chips instead, but we wouldn't have such a plethora of potatoes if not for the prodigious production of the states of Idaho and Washington -- they provide about half of all the potatoes in the United States today!
• Americans love celebrating the Fourth outdoors: About 74 million Americans fire up their BBQ grill every Fourth of July.
• The Chinese contribution: Did you know that Americans have spent more than $211 million on fireworks that were imported from China?

No matter how your family chooses to celebrate the Fourth, stay safe, take precautions, and don't forget to brush after your fabulous Fourth feast!
