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!

Xerostomia might sound like a serious and rare condition, but it’s more common than you think. If you’ve been feeling like your mouth is constantly dry, you may already be having your first encounter with it.

Xerostomia refers to when you have a dry mouth due to absent or reduced saliva flow. Now you might assume this is not a big deal, but a lack of saliva can threaten your dental health or worse, because it can be a sign of a bigger overall problem.

Some of the more common symptoms to watch for are a sore throat, difficulty swallowing, a burning sensation on the tongue, and of course, a significant lack of saliva. Because xerostomia entails a reduction in saliva, you have less of a buffer between your teeth and the food you eat, which makes you more vulnerable to cavities and tooth decay. It also means that food is more likely to get stuck in your mouth.

So what causes xerostomia? There can be many different culprits. One of the most common causes involves medication. If you’re taking antidepressants, muscle relaxers, anti-diarrhea medicine, anti-anxiety medicine, or antihistamines, this could be the reason for your xerostomia.

Dry mouth may also be a warning sign for other health issues. These can include lupus, diabetes, thyroid disease, arthritis, or hypertension. Patients that receive any kind of chemotherapy might also experience xerostomia as a side effect of their treatment.

If you’re experiencing symptoms of dry mouth, there are several things you can do:

• This may seem obvious, but you should drink generous amounts of water. If you’re taking any of the medications known to cause xerostomia, a glass of water before and after administering the medication could be helpful.
• Avoid heavily caffeinated drinks, since they will dehydrate you further.
• Opt for a mouthwash that contains little to no alcohol.
• Consume excessively sugary or acidic foods in moderation, if at all.
• Try adding a humidifier to your room while you sleep, to add moisture to the air you’ll be breathing.

As always, stay on top of your brushing and flossing routines, and if you feel you might be suffering from xerostomia, please let Sandra Martin know during your next visit to our Wake Forrest, North Carolina office. We’re happy to recommend products we’ve found to be successful in treating xerostomia.

Xylitol tastes sweet, but unlike sugar, it is not converted to acid that can cause your teeth to decay. It’s a naturally occurring sweetener found in plants, fruits, and vegetables; even the human body produces it in small amounts. Xylitol is widely used in sugar-free chewing gum, mints, candies, and even certain forms of medicine.

The World Health Organization has approved xylitol because only a small amount is needed for its health benefits. It’s even safe for diabetics, with a glycemic index of only seven. Xylitol has 40% fewer calories than other types of carbs: less than three calories per gram.

So how can this natural sweetener benefit your oral health? Take a look at the facts. Tooth decay starts when bacteria consumes the sugars left in your mouth. When you eat sugary foods, the bacteria on your teeth will multiply and make acid that can destroy your enamel.

Xylitol is derived from fibrous parts of plants, so it does not break down like a regular sugar. It actually helps maintain a neutral pH level in the mouth, which in turn prevents bacteria from sticking to the teeth. The bacteria are then unable to digest xylitol, which means your teeth won’t develop enamel damage and cavities.

Studies have shown the consumption of xylitol as a sugar substitute or a dietary addition had a dramatic reduction in new cavities and even reversed existing cavities. These effects are long lasting: low cavity rates remained years after the trials were done.

When there’s less bacteria and acid in your mouth due to xylitol, your teeth stay healthier. The more frequently it’s ingested, the more you will prevent enamel damage.

Aim to consume around five grams a day, or one gram every three hours if possible. You can do this by consuming gum, tablets, candy, or mints that have xylitol as one of the first ingredients after your meals. You can find these products in health food stores and specialty grocery stores.

Since xylitol replaces sugar on a one-to-one ratio, it’s used in several common items:

• Toothpaste
• Mouth rinse
• Baby oral wipes, gel, and pacifiers
• Nasal wash
• Dry mouth spray
• Granulated forms for cooking
• Granulated packets to add to drinks
• Commercially prepared foods

Make sure to pick up items that contain xylitol the next time you’re at the store! This is an easy way to maintain great oral health. If you have specific questions about xylitol, ask Sandra Martin during your next appointment at our Wake Forrest, North Carolina office.

Father’s Day is coming up, and, just in case your dad has enough ties, we have some gifting suggestions for you. Here’s a selection of gifts large and small tailored to your dad’s interests and his dental health.

• The Outdoor Dad

If your dad is happiest out camping, or his most relaxed at the lake fishing, or gets rid of stress with a 20-mile hike, help your dad stay happy, relaxed, and stress-free with an emergency dental kit for any unexpected problems which might crop up during his adventures.

You can find these lightweight kits in sporting stores and online. Supplies like cotton rolls, dental floss, oral pain relievers, a dental mirror, and even temporary fillings are included, because, as your dad no doubt told you, it’s always best to be prepared!

• The High-Tech Dad

For the dad who’s first with the latest in smart phones and tablets, a new smart toothbrush might tick all the boxes.

Modern electric toothbrushes have plenty of options for the tech-savvy. They come with different settings for brushing and massaging. They can let your dad know if he’s brushed long enough (two minutes, please!), if he’s brushing too hard, or when the brush head needs to be retired. Smart models even link to apps, which can, among other things, map out any missed spots in his brushing coverage or suggest more effective brushing angles.

• The Dad on the Go

With his active life, any gift which makes your dad’s busy schedule run more smoothly is a good thing—such as a portable kit filled with dental necessities.

A travel toothbrush, a small tube of his favorite toothpaste, a compact mirror, dental picks, dental floss, and a mini-bottle of mouthwash are great basics for a confident smile any time of day. Put everything in a sturdy lightweight travel bag. And don’t forget to include a pack of sugarless gum! Sugarless gum helps increase saliva flow (for better hydration) and decrease oral acidity (to help prevent enamel erosion).

• The Dad with Gourmet Taste

If your dad has foodie tastes, a thoughtfully curated gift basket is a great idea for pleasing his palate and supporting his dental health.

Include items like cheeses, which are full of calcium and phosphorus for strong teeth. Fresh fruits provide vitamins for healthy teeth and gums. Nuts offer plenty of tooth-healthy minerals and vitamins, as well as packing a protein punch. For your dad’s sweet tooth, dark chocolate (at least 70% cacao) is a great source of antioxidants, iron, zinc, magnesium and other valuable minerals. It’s lower in sugar content, and some studies suggest that dark chocolate has cavity-fighting properties and supports gum health.

• The Athletic Dad

He can deke the goalie, throw a perfect spiral, and hit those threes from downtown. Or, at the very least, he gives his favorite sport his best shot! If your dad has some of his happiest moments, win or lose, on the ice, the gridiron, the court, or any other sporty venue, consider a custom mouth guard to protect his winning smile.

Custom guards are more comfortable than store-bought options because they are molded to fit the user’s teeth and mouth precisely. This is especially helpful for those with dental work like braces or bridges. And, because the fit is custom, breathing and talking are easier.

• The Picture-Perfect Dad

Your dad’s smiles light up family photos! And if he’s ever expressed an interest in lightening and brightening that beautiful smile, a professional whitening treatment might be a perfect gift.

Professional whitening at our Wake Forrest, North Carolina office is the most effective way to brighten teeth, with results which are generally faster and more long lasting than over-the-counter treatments. And it’s done with your dad’s dental health in mind, with a checkup to make sure his teeth are in perfect shape before whitening, and with protective measures in place for sensitive mouth and gum tissue.

Of course your dad will appreciate another tie, or any other traditional gift, because you give it to him. But just in case you’re looking for something a little different to celebrate Father’s Day, choose a dental-healthy gift designed with your dad in mind—so you can celebrate his smile for years to come!
