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. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying know how your experiments turned out the next time you visit our Hiawatha, IA office!

Fluoride is a mineral that plays an essential role in oral health. In fact, the significant reduction in American tooth decay in recent decades can be attributed to a greater availability of fluoride in public water supplies, toothpaste, and other resources. When it comes in contact with the teeth, fluoride helps protect the enamel from acid and plaque bacteria. In some cases, it can even reverse tooth decay in its earliest stages.

Despite the benefits of fluoride, tooth decay is still common, especially among teenagers. The Centers for Disease Control reports that cavities can be found in more than half of young teens and two-thirds of older teens over age 16. Many of those teens are deficient in fluoride, either due to a lack of public water fluoridation or the use of bottled water. So how can parents ensure their teens are getting the fluoride they need to facilitate strong, healthy teeth?

Monitor Fluoride Exposure

Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying and our team at Blair Ridge Dental recommend you start by measuring your teen’s fluoride exposure. Make sure you purchase fluoridated toothpaste for your household, and find out if your tap water is fluoridated. If your teen primarily consumes bottled water, examine the bottle to determine whether fluoride has been added. The majority of bottled waters are not supplemented with fluoride, but those that are will be clearly labeled.

Fluoride Supplementation

Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying may recommend topical fluoride treatments at routine dental exams. These treatments are painless for your teen and may help establish stronger enamel that is more resistant to plaque and tooth decay. If you have a public water supply that is non-fluoridated, we may recommend fluoride supplementation between visits. These can be administered as drops, tablets, or vitamins.

Keep in mind that fluoride is most important for children and teens under the age of 16. Be proactive about your teen’s oral health by speaking with us about your family’s fluoride needs at your next dental visit.

We’re parents, so we worry. It comes with the job description! That’s why we make sure our children use toothbrushes with soft bristles and apply just the right amount of fluoride toothpaste. That’s why we make regular appointments with their dentists for preventive care and examinations. And that’s why we want to know all about the X-rays that are used in our children’s dental exams.

First of all, it’s reassuring to know that the amount of radiation we are exposed to from a single dental X-ray is very small. A set of bitewing X-rays, for example, exposes us to an amount of radiation that is approximately the same as the amount of radiation we receive from our natural surroundings in a single day.

Even so, dentists are especially careful when children need X-rays, because their bodies are still growing and their cells are developing more rapidly than adults. And children often have different dental needs than adults, which can require different types of imaging.

In addition to the usual X-rays that are taken to discover cavities, fractures, or other problems, young patients might need X-rays:

• To confirm that their teeth and jaws are developing properly
• To make sure, as permanent teeth come in, that baby teeth aren’t interfering with the arrival and position of adult teeth, and that there’s enough space in the jaw to accommodate them
• To plan orthodontic treatment
• To check the progress and placement of wisdom teeth

So, how do dentists make sure your child’s radiation exposure during X-ray procedures is as minimal as possible?

Radiologists, the physicians who specialize in imaging procedures and diagnoses, recommend that all dentists and doctors follow the safety principal known as ALARA: “As Low As Reasonably Achievable.” This means using the lowest X-ray exposure necessary to achieve precise diagnostic results for all dental and medical patients.

Moreover, radiologists are devoted to raising awareness about the latest advances in imaging safety not only for dental and medical practitioners, but for the public, as well. With children in mind, pediatric radiologists from a number of professional associations have joined together to create the Image Gently Alliance, offering specific guidelines for the specific needs of young patients.

And because we are always concerned about the safety of our patients, dental associations around the world, including the American Academy of Pediatric Dentistry, the American Dental Association, the American Dental Hygienists’ Association, the Canadian Academy of Pediatric Dentistry, and the Canadian Dental Hygienists Association, are Image Gently Alliance members.

The guidelines recommended for X-rays and other imaging for young people have been designed to make sure all children have the safest experience possible whenever they visit the dentist or the doctor. As dental professionals, Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying and our team ensure that imaging is safe and effective in a number of ways:

• We take X-rays only when they are necessary.
• We provide protective gear, such as apron shields and thyroid collars, whenever needed.
• We make use of modern X-ray equipment, for both traditional X-rays and digital X-rays, which exposes patients to a lower amount of radiation than ever before.
• We set exposure times based on each child’s size and age, using the fastest film or digital image receptors.

We know your child’s health and safety are always on your mind, so you’re proactive about dental care. And your child’s health and safety are always on our minds, too, so we’re proactive when it comes to all of our dental procedures available at our Hiawatha, IA office.

Please free to talk with Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying about X-rays and any other imaging we recommend for your child. We want to put your mind at ease, knowing that X-rays will be taken only when necessary, will be geared to your child’s age and weight, and will be used with protective equipment in place. Because ensuring your child’s dental health and safety? That comes with our job description!

Perhaps you’ve heard your friends talking about dental sealants, and how well they prevent cavities. And as soon as your child’s permanent molars come in, you absolutely plan to make an appointment at our Hiawatha, IA office for this treatment. But should you also be concerned with your child’s baby teeth? Could they benefit from sealants too?

Even though those beautiful baby teeth are going to be replaced with permanent teeth, they should still be protected. Primary teeth help with speech development, enable your child to develop proper chewing and eating habits, and serve as place holders so that permanent teeth can erupt in the correct place. That’s why you’ve been so careful to help your child brush and floss twice daily, and make regular visits to our office for exams and cleanings.

But some teeth are just harder to keep clean with regular brushing than others. Primary molars, just like permanent ones, have depressions and grooves on the chewing surfaces. These grooves collect bacteria and food particles that are hard for bristles to reach, providing a perfect opportunity for cavities to develop in those little molars.

Cavities are not the only problem which can affect primary teeth. Because baby teeth have thinner layers of protective enamel, a cavity can actually reach the pulp (the center of the tooth) more quickly, leading to pain and potential infection.

While baby teeth can be treated, with fillings, restorations, and even stainless steel crowns, preventing tooth decay is always our first, best choice. And dental sealants are recommended by the American Academy of Pediatric Dentistry and the American Dental Association as one of the most effective ways to prevent cavities in both baby teeth and adult teeth.

Dental sealants are safe and effective.  Sealants are thin coatings (usually a plastic resin or other dental material) that cover a molar’s grooves and depressions, making it impossible for bacteria and food particles to collect there. Applying them is a simple, pain-free process.

Each tooth will be examined first. If we find any signs of decay starting, we will gently treat that area before applying the sealant. After the tooth is cleaned and dried, an etching solution will be brushed on to the surface area being sealed. This etching roughens the surface so that the sealant will hold to the tooth more effectively. A thin coat of the sealant is then painted on and hardened under a curing light.

That’s all there is to it! Sealants typically last from three to five years, and some last even longer. Keep up your regular careful brushing and flossing, and we will monitor the condition of the sealants at each exam.

Talk to Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying about dental sealants. We’ll let you know if your child can benefit from the procedure even before those baby teeth give way to permanent ones. It’s never too early to prevent tooth decay!
