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. Goodall know how your experiments turned out the next time you visit our Frisco office!

While the last baby teeth generally aren’t lost until age ten or 11, most children stop believing in the tooth fairy by the time they're seven or eight. Of course, children are more than happy to play along with the game when there’s money at stake! While it is impossible to know what the tooth fairy does with all those teeth (are they labeled and stored like museum pieces in a giant fairytale castle?), it is possible to trace the history and myth of the tooth fairy to several cultures and traditions. Dr. Goodall and our team learned about some interesting myths about the tooth fairy!

The Middle Ages

Legend has it that Europeans in the Middle Ages believed a witch could curse someone by using their teeth, so it was important to dispose of baby teeth correctly. Teeth were swallowed, buried, or burned. Sometimes baby teeth were even left for rodents to eat. Despite being pests, rodents were valued for their strong teeth; it was generally believed a tooth fed to a rodent would lead to the development of a healthy and strong adult tooth.

Eighteenth Century France

The tooth fairy myth began to show more characteristics of a conventional fairytale in 18^th century France. La Bonne Petite Souris, a bedtime story, tells the strange tale of a fairy that changes into a mouse to help a good queen defeat an evil king. The mouse secretly hides under the evil king’s pillow and defeats him by knocking out his teeth.

Scandinavian Lore

So, why does the tooth fairy leave money under the pillow? The idea of exchanging a tooth for coins originated in Scandinavia. Vikings paid children for a lost tooth. Teeth were worn on necklaces as good luck charms in battle. While the idea of exchanging a tooth for coins quickly spread throughout the rest of Europe, a fierce, horn-helmeted Viking is far cry from the image of a fairy collecting teeth.

While the tooth fairy as children know her today didn’t make an appearance until the 1900s, tooth myths and rites of passage have existed in numerous cultures since the dawn of time.

Millions of people, around Frisco and beyond, wear green on St. Patrick’s Day so they can show their spirit for the holiday and avoid getting pinched. While it may be easy for you to throw on a green shirt, sport a St. Patrick’s Day button, or wear a pair of emerald-hued shoes, if you’re an avid St. Patty’s Day enthusiast you may want to try something different this year. Dr. Goodall thought of a few ideas that will help you take your holiday spirit to the next level:

Visit Chicago’s Green River

If you happen to be near the Windy City during St. Patrick’s Day or you’re thinking of planning a trip, don’t miss out on going downtown to watch the large-scale celebration that kicks off when the city dyes the river bright green. According to the Chicago Sun-Times, Chicago has been celebrating the holiday with this tradition for more than 50 years, with tens of thousands of people gathering annually to witness the mysterious dying process and the stunning result.

Don Green Face Paint

Just like an avid sports fan on game day, you can use green face paints to showcase your enthusiasm for this holiday. Avoid breakouts or allergic reactions by only using paints that are specifically meant to be applied to the skin. A little bit of face paint can cover a large area, so feel free to get creative and decorate the whole family on St. Patrick’s Day.

Eat Green All Day

Not a fan of green eggs and ham? With the increasing popularity of green smoothies, there’s no better time to get in on this health craze. To create a green smoothie without the aid of food coloring, you can simply blend a generous amount of a leafy green vegetable, such as spinach or kale, with the ingredients that you would typically use to make a smoothie, like fruit, ice, milk, or juice. Keep the trend going throughout the day by using those same vegetables to create a green soup, egg salad, or a batch of bright green pastries. As an added bonus, you’ll get a healthy dose of vitamins without changing the taste of most of these foods.

If your old holiday routine has gotten stale, leave your green T-shirt in the drawer and try one or all of these tips. Don’t be surprised if you have so much fun that you decide to start a new, annual St. Patrick’s Day tradition! Have a happy St. Paddy’s day from More Than Smiles!

If you have been bringing your baby in for regular checkups since that first tooth arrived, you might expect that he or she is already familiar with Dr. Goodall and our staff. Often, though, months pass between visits, which is a very long time for a child. How can you make your preschooler’s return visit a happy one? We have some suggestions!

Before Your Visit

• Prepare your child for her visit. Simple explanations are best for a young child. You might tell your daughter that a dentist is a doctor who helps keep her teeth strong and healthy. Let her know a bit about what will happen. Being told, “You will sit in a special chair,” or, “Can you open wide so we can count your teeth?” will give her some idea of what it’s like to visit our office.
• There are many entertaining books for young children about visiting the dentist. Reading some of these to her for a few days before the appointment will let her know what to expect.
• Use playtime to prepare. You might count your daughter’s teeth or let her “play dentist” and brush the teeth of her favorite doll or stuffed animal.

When You Arrive

• Your attitude can be contagious! If you treat a visit to the dentist like any other outing, chances are your child will too. Your calm presence is exactly what your child needs.
• You might want to come a bit early to let your son explore the office. Bring a favorite toy or book to keep him entertained if you need to. A favorite stuffed toy can be a comfort in an unfamiliar place.
• If you are with your child during his checkup, follow our lead. Don’t be concerned if your child seems uncooperative at first or even throws a tantrum—we are used to working with children, and have techniques to make his experience as relaxed and as positive as we possibly can.
