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. Jason Rector know how your experiments turned out the next time you visit our Ocean Springs office!

Since the introduction of the power toothbrush in the 1960s, this tool has undergone many technological advances, from design and bristle motions to rotation oscillation and sonic vibration.

What is rotation oscillation? That’s when the head of the toothbrush alternately rotates in one direction and then the other. Power toothbrushes can deliver up to 50,000 strokes per minute, which is much more effective than the average 300 strokes per minute with a manual toothbrush.

A smaller brush head is available for hard-to-reach areas, which is a good alternative for small mouths. The brush heads are replaceable and should be changed every three to six months. Each family member should have his or her own brush head while sharing the base motor. What a great deal! Check the handle size. A large handle is better for members of the household with arthritis, children, or family with other physical disabilities.

A rechargeable toothbrush is ideal. It should deliver enough power on a full charge for one week of brushing.

We recommend you brush for a minimum of two minutes. Some electric toothbrushes include a signal you can hear, such as a beep every 30 seconds, to indicate it's time to switch to a different area of the mouth. Others sound an alert after the full two minutes has elapsed.

Will an electric toothbrush harm the teeth or gums? Studies indicate that people tend to apply more damaging pressure to their teeth and gums during manual brushing than when they use an electric toothbrush. If you experience tooth sensitivity, choose a model with pressure sensors that stop the toothbrush any time you press too hard.

Who would benefit from an electric toothbrush? Everyone! Consumers with a physical disability may have specific needs that power toothbrushes can address. Children also tend to maintain better oral health hygiene when they use an automatic toothbrush. Plus, many of them find it fun to brush!

Automatic toothbrushes really do remove debris better than the old-fashioned way. You may have heard the term “biofilm.” Better known as plaque when it occurs in the mouth, biofilm is the debris and bacteria that cause infections to your teeth. It regenerates quickly, so healthy habits are the best defense for a healthier you! With a healthier mouth, you face a lower risk of gum disease and other conditions like heart disease: mouth health has been linked to heart health.

Memorial Day didn't become an official holiday until 1971, but Americans started gathering annually in the spring to remember those who lost their lives in war during the 1860s, right after the Civil War. Celebrated on the last Monday in May, people still decorate the grave sites of war veterans and hold memorial services, but Memorial Day has also evolved into a day that signifies the beginning of summer.

During the summer months, many people take road trips to visit family members. Some head off to the airport to enjoy a long-awaited vacation far away, while others look forward to spending time with friends and family at home. However you spend Memorial Day and the subsequent summer months, there are a few things you can take care of to ensure your summertime is enjoyable.

Checklist for an Enjoyable Summer

• Have the AC Checked. During the hottest days of summer, many families find themselves sweating it out due to a broken air conditioning system. Be proactive so you can avoid waiting for hours or days because the HVAC repair person is booked solid. Have your air conditioning system checked before or around Memorial Day each year.
• Ensure Security While You're Away. When you leave for vacation, the last thing you should have to worry about is the security of your home. Install a home security system, if possible, and put a timer on your lights so they go on and off at normal hours. You can also alert your local police department that you'll be gone, and ask them to drive by your house once in a while to make sure everything is okay.
• Visit Dr. Jason Rector Before Vacation. Many people put off exams until after summer vacation. Avoid the crowds and make sure your physical and oral health are in top shape prior to vacation time so there are no unpleasant surprises.

Our team at Rector Pediatric Dental wants you to look forward to Memorial Day and the days of summer by preparing to spend the time safely and comfortably. As you plan ahead, take care of your health and secure your home, you can place your focus on creating memories with family members and friends while enjoying your favorite Memorial Day traditions.

You’ve been going to Rector Pediatric Dental for a while now, so you pretty much know what to expect when you get to our Ocean Springs office.

You’ll see Dr. Jason Rector, your hygienist, and all the other members of your friendly dental team again. You’ll sit in a comfortable chair just your size. And you’ll have a checkup to make sure your teeth are healthy.

But once you’re sitting back in that comfortable chair, you might be wondering just what exactly gets checked during your checkup. The answer is, a lot!

• Checking Your Tooth and Gum Health

It’s important to have regular checkups because finding a small problem right away, like a weak spot in your tooth enamel, means your dentist can prevent it from becoming a bigger problem, like a cavity, later!

So your dentist will carefully examine each tooth for signs of tooth decay, using a little mirror to see behind your front teeth and around those hard-to-see teeth in the back of your mouth. The visible part of your smile doesn’t always tell everything about your dental health, though. At some checkups, you might need X-rays to make sure the insides of your teeth and their roots are healthy.

Oral health means more than just your teeth. That’s why your dentist will examine your gums and the inside of your mouth, too.

• Checking Your Bite

Dr. Jason Rector will check the way your teeth fit together when you bite, and can take X-ray images to show the size and shape of your jaw bones and the size and position of your permanent teeth before they even come in.

If your teeth and jaws fit don’t together just right, or if it looks like there might not be enough room for all your adult teeth to come in without crowding, your dentist might recommend pre-orthodontic or orthodontic treatment. 

• Cleaning Your Teeth

Plaque can hide in hard-to-reach places between your teeth and around your gums. You might know that plaque can cause cavities if it’s not brushed away, but did you know that plaque can also hurt your gums? That’s why an expert cleaning is usually part of every checkup.

Your hygienist will use special dental tools and carefully remove any plaque you might have missed or any tartar (hardened plaque) that’s built up over time. Then after flossing and rinsing, you’ll have a clean, sparkling, plaque-free smile.

Bonus: Your dental hygienist can teach you how to brush and floss better if you’ve been missing a few spots!

• Can Your Teeth Use Extra Protection?

Once your teeth are cleaned and examined, your dentist might use a fluoride treatment or sealants to give your teeth extra protection against cavities.

Fluoride treatments help make your tooth enamel stronger. If your dentist thinks you need this kind of fluoride protection, your teeth will be coated with a special fluoride gel or varnish or foam. This treatment doesn’t take long and will strengthen your enamel for months afterward.

People’s molars get the most cavities because their uneven surfaces make good places for plaque and bits of food to hide from brushes. A sealant is a thin coating which is brushed on the top of your molars to prevent plaque from hurting your enamel.

• Checking In with You!

Part of your checkup is talking to your dentist about how you can protect and even improve your dental health.

• Find out whether the foods you eat make your tooth enamel stronger—or weaker.
• Discover how brushing and flossing help prevent tooth decay and gum disease, and see if your brushing and flossing skills need any work.
• Learn how to protect your teeth during active sports (hint: wear a mouthguard).
• If you have habits which can hurt your teeth, like nail biting, get advice on how to quit.
• Don’t forget to ask any questions you might have!

Your checkup might be a little different, because your exam is designed just for you, but there’s one thing which all of us can expect. Visit our Ocean Springs pediatric dental office for regular checkups, work together with your dental team, and you can expect a healthier, happier smile!
