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!

Whether you’ve lost a tooth from decay, are preparing for dentures, or were born with a gap where a tooth should have been, you could be a candidate for dental implants.

Dental implants have changed a lot since their debut in 1965, thanks to continuing advances in design and technology. Today, you no longer have to worry about whether dental implants might have a negative aesthetic impact on your smile.

So what are dental implants? Pretty much what they sound like: An implant is a replacement tooth that substitutes for a missing natural one. It gets placed through several steps; it’s a process that can take a few months.

The initial step involves the surgical implantation of the implant root, which resembles a small screw. After that’s placed, the top is covered with gum tissue to enable it to heal faster. This is an essential phase in the process, since this portion of the implant will serve as the base of support for everything else.

In the second step, the implant gets uncovered and an implant restoration (or crown) is created and affixed to it. After that, you’ve got yourself a new tooth!

While dental implants require a little special care, it’s all easily manageable. All you have to do at home is make sure you brush and floss your implant daily, the same as you would for any other tooth. Although an implant can’t develop a cavity, if something were to get stuck in it, that could lead to a gum infection.

If you have any other questions about dental implants, give our Sioux Falls, SD office a call!

The sounds of the season are filling the air—falling leaves rustling along the sidewalk, football cheers, holiday greetings—and the coughs and sneezes of your fellow sufferers. Yes, it’s cold and flu season, and you’re one of the unfortunate people who’s caught whatever it is that’s been going around. While you’re recuperating, here are some tips for looking after yourself and your dental health.

• Keep Hydrated

Fevers, sweating, diarrhea, and vomiting can all lead to dehydration. You know how serious that can be for your overall health, but it also leads to problems for your oral health. Lowered saliva production puts you at an increased risk for cavities, since saliva washes away food particles and bacteria, neutralizes cavity-causing acids, and helps strengthen tooth enamel. In addition to the dehydration illness can cause, many over the counter medications leave your mouth dry as well. Be sure to drink fluids throughout your illness, and, as always, try to avoid sugary beverages and acidic drinks.

• Keep Up Your Dental Hygiene

You may feel like you never want to get out of bed again, but it’s important to maintain your dental routine. Brushing and flossing are still necessary to protect your teeth and gums. And try gargling with warm saltwater or a mouth rinse. You’ll not only soothe a sore throat and help prevent the bad breath that sinus problems can cause, but you’ll also reduce oral bacteria and plaque.

• Keep Away from Your Toothbrush after Vomiting

Even though cleaning your mouth and teeth might be the first thing you want do to after throwing up, wait at least half an hour before brushing your teeth. Cavities occur over time when tooth enamel is weakened by the acids oral bacteria produce. When you vomit, your teeth are exposed to much stronger stomach acids, and immediate brushing simply brushes these acids on to your enamel. One common recommendation is to mix a teaspoon of baking soda with a glass of water, swish it around your mouth, and spit it out. Or simply use a glass of plain water, and repeat if needed.

• Keep Your Cough under Control

Here’s a tip your family, friends, co-workers, and fellow public transportation users will thank you for: If you are sick, stay home. If you do find yourself coughing while around others, cover your mouth. Cough into a tissue instead of your hands or the open air. If you don’t have a tissue available, cough into your upper sleeve.  And while you’re protecting others, protect your tooth enamel. Replace overly sweet cough syrups with tablets, and, if you are using cough drops, remember that sucking on a sugary cough drop is like sucking on candy. Look for the sugar-free variety and use only as directed.

• Don’t Keep Your Toothbrush

Now that you’re feeling better, it might be time to throw out your toothbrush. The chances of re-infection are low (unless you have a compromised immune system), but we often hang on to our toothbrushes long after their effective days are past. A toothbrush should only last around three to four months. If yours is older than that, this is a perfect opportunity to replace a brush that might be getting a bit long in the tooth with a fresh, germ-free model.

Above all, be good to yourself when you are ill. Drink healthy fluids, maintain your dental routine, and treat your teeth and your body with care. Here’s wishing you a speedy recovery, continuing dental health, and a season filled with beautiful smiles.

Dr. Cody Henriksen and our team want you to have the healthiest possible smile in the healthiest possible body. Oral cancer can affect the mouth, tongue, throat and jaw. Early detection is vital for the best possible outcome when treating this disease. That is why we check for symptoms of oral cancer at every dental examination.

What can you do to reduce the chance of oral cancer?  Reduce your risk factors. You can help prevent oral cancer by adopting these healthy habits:

• Don’t smoke. Don’t chew tobacco. Don’t use a pipe. If you use any tobacco products, quit. Tobacco use is the single largest risk factor for head and neck cancers. Talk to us—we have suggestions for helping you break the habit.
• Drink alcohol in moderation. Heavy drinkers have a higher rate of oral cancer. More than one to two drinks per day can be considered heavy drinking, depending on factors such as weight, age, and even gender. Check with your doctor to find your personal definition of moderation.
• Eat a healthy diet. Cancer-fighting fruits and vegetables are a great addition to any menu.
• Protect yourself from the sun. Help prevent sun-related lip cancers by always wearing a UVA/UVB blocking sun screen or lip balm whenever you are working or playing outside—and reapply frequently.
• Some forms of the HPV virus have been linked to oral cancer, and those affected are generally younger and less likely to be smokers. Research indicates that the HPV vaccine, known for preventing several types of cancer, might also help prevent HPV-related oral cancers.
• Schedule regular dental exams. We are trained to recognize oral cancer and precancerous conditions that you might miss.

Of course, cancer can occur even with the healthiest habits. Do come see us if you detect any of these symptoms:

• A sore or ulcer that doesn’t heal, or persistent tenderness and pain in the mouth
• Lingering sore throat, hoarseness, or vocal changes
• Pain in the neck or ear that doesn’t go away
• A lump, a rough or thickened area, or eroded tissue in the skin lining the mouth
• Red or white patches in the lining of the mouth or on the tongue
• Difficulties chewing, swallowing, speaking, or moving the tongue or jaw
• Numbness in the tongue or mouth
• Changes in the way your natural teeth or your dentures fit together.

Not every symptom is caused by cancer, but it is important to rule out the possibility. We are trained to recognize early signs of oral cancer, and can recommend further tests if needed. Call our Sioux Falls, SD office immediately if you have any concerns. Early detection and treatment lead to the most successful outcomes.
