Tooth Worms? The History of Cavities and Tooth Fillings

January 29th, 2025

Scientists have discovered tooth decay in specimens that are more than 15,000 years old. The ancients once thought that cavities were caused by something called “tooth worms” … Eew! They didn’t exist, of course, but how else could humans explain the holes that cavities make in teeth?

The appearance of cavities on a widespread basis is often traced to the rise of farming. The new diet filled with grains and carbs made our mouths a haven for cavity-causing bacteria. As we added more sugar to our diets, our teeth got worse.

The “tooth worm” idea didn’t completely disappear until the 1700s when scientists finally began to understand the process of dental caries. Once that part of the puzzle was solved, they began focusing on filling existing cavities and preventing new ones.

Dental Fillings Come of Age

Many different materials, including beeswax, cork, aluminum, tin, and even asbestos, have been used to fill the holes caused by dental decay. Sometime in the mid-1800s, however, dentists began to use metal fillings such as gold, platinum, silver and lead amalgams.

The amalgam we use today is mixed from liquid mercury, silver, tin, copper, zinc, and other metals, but some patients still like the look of a gold filling. Newer options include composite-resin fillings, which are made from a tooth-colored mixture of plastic resin and finely ground glass-like or quartz particles that form a durable and discreet filling. Porcelain or ceramic fillings are natural in color, but more resistant to staining.

Dr. Chad Vanourny can help decide which filling is best for you, based on cost as well as your dental and lifestyle needs. You may not have “tooth worms,” but if you have cavities, contact our Charlotte office so we can take the proper action to protect the health of your mouth.

Three Surprising Causes of Bad Breath

January 22nd, 2025

Rumor has it that the Queen of England doesn’t allow garlic in the palace. And, even if you have no royal duties in the near future, it might be a good idea to avoid foods like garlic and onion before a big presentation or a first date. But if your diet is filled with mint, fresh apples, and parsley and you still worry about your breath, here are some common causes for bad breath that you might not have considered.

  • A Slip of the Tongue

We brush and floss to remove food particles and bacteria. After all, bacteria that linger in the mouth produce acids that damage tooth enamel and cause bad breath. But there is one important brushing target you might be overlooking—your tongue.

Remove food particles and bacteria on the surface of the tongue with a gentle brushing after you have finished cleaning your teeth. With a dab of toothpaste, brush the top of your tongue gently from back to front. There are also tools called tongue scrapers available that are specifically designed to remove food particles and bacteria from the tongue’s surface. However you choose to clean your tongue, remember to move from the back to the front, and always clean gently.

  • A Dry Spell

We spend the vast majority of our day not brushing our teeth. What helps keep breath fresh even during the hours between brushings? Saliva! As saliva bathes the teeth throughout the day, it not only washes away food particles and bacteria, but also neutralizes the enamel-damaging acids that are produced by bacteria. Yet another benefit? Saliva is not a friendly environment for the oral bacteria that produce volatile sulfur compounds (VSCs). It is these compounds that cause most of the unpleasant odors we know as bad breath.

If you are drinking the recommended amount of water each day, you are helping your body produce saliva and fight bad breath. Sometimes, a medical condition called dry mouth, or xerostomia, interferes with saliva production. Talk to Dr. Chad Vanourny about ways to deal with dry mouth. Solutions as simple as drinking more fluids or chewing sugarless gum can help, or we can suggest over-the-counter products or prescription medications if needed.

  • A Bad Night’s Sleep

We’re all familiar with the concept of morning breath. As we sleep, our saliva production naturally decreases. It’s like a nightly version of dry mouth. Without normal levels of saliva, bacterial growth takes off, VSC’s are produced in greater quantities, and we wake up wondering what on earth happened to that fresh feeling we had after brushing the night before.

Unfortunately for snorers, nighttime brings more problems. Snoring leads to mouth breathing, and mouth breathing creates an even drier environment where oral bacteria increase more quickly. If you find you are consistently waking up with an especially unpleasant case of morning breath, you could be a chronic snorer without even realizing it. If you discover or suspect you have a snoring problem, talk to Dr. Chad Vanourny or your GP. Snoring can have serious health consequences, so let’s discuss possible solutions.

One important note to end on: if you have eliminated all the obvious causes of halitosis but still have persistent bad breath, give our Charlotte office a call. Chronic bad breath can be a symptom of serious gum disease, oral infections, illnesses such as diabetes or kidney disease, and other medical conditions that should be treated as soon as possible. If the topic is bad breath, let’s make sure garlic is the only thing you have to worry about.

Why Baby Teeth Matter

January 15th, 2025

Sleepless nights, crankiness, drooling—how can such tiny teeth cause such a big fuss? But all those uncomfortable days and nights are forgotten when your baby’s first teeth make their appearance. Why? Well, certainly because your child is happier, but also because you know baby teeth, or primary teeth, are important for your child’s growth in so many different ways.

  • Chewing and Eating

Your baby might enjoy solid foods at an early age, but real chewing doesn’t happen until all the baby molars appear between the ages of one to three years. This is the time to feed children size-appropriate and texture-appropriate foods so they acquire proper chewing and eating habits for healthy digestion. Chewing also helps develop your child’s jaw and facial muscles.

  • Developing Speech

Pronouncing many of the common sounds used in speech often requires tongue and teeth working together. If teeth are missing or there is a bite problem such as an open bite, it might be more difficult to pronounce words properly. This could be only a temporary delay, or it could require speech therapy when your child is older.

  • Setting the Stage for Permanent Teeth

Baby teeth not only help with speech and jaw development, but they serve as space holders for permanent teeth. If a primary tooth is lost too early, a permanent tooth might “drift” into the empty space. The adult tooth will not have the room to fit where it should, and crowding or misalignment can occur. This might cause orthodontic problems in the future.

  • Learning Healthy Dental Habits

You are your baby’s first dental health care provider! Wiping the gums and erupting teeth with a soft damp cloth after meals, gently brushing baby teeth when your toddler is young, teaching how to brush as your child gets older, helping to establish daily routines for brushing—all these practices will prepare your child for lifelong healthy dental habits.

  • Making the Dentist a Regular Part of Your Child’s Life

Your child should visit our Charlotte office soon after that first tooth comes in, and definitely by the age of 12 months. Dr. Chad Vanourny can help with suggestions for your brushing and flossing routine, make sure your child’s teeth are healthy and clean, and ensure that teething progress is on track. In later visits, we will examine your child’s primary teeth and gums, and treat any problems, such as cavities, before they can become serious.

It turns out that baby teeth really are a big deal. Talk to us about suggestions for caring for your toddler’s teeth and about any questions you may have about teething progress, jaw and facial structure, speech development, or any other concerns at any time. We want to have a happy relationship with your child from the very start for a lifetime of healthy and confident smiles.

What is a water pick and do I need one?

January 8th, 2025

Water picks, sometimes called “oral irrigators,” make an excellent addition to your regular home care regimen of brushing and flossing. Especially helpful to those who suffer from periodontal disease and those patients of ours undergoing orthodontic treatment with full-bracketed braces, water picks use powerful tiny bursts of water to dislodge food scraps, bacteria, and other debris nestled in the crevices of your mouth. Children undergoing orthodontic treatment may find using a water pick is beneficial if their toothbrush bristles tend to get caught on their wires or brackets.

When you use a water pick, you’re not only dislodging any particles or debris and bacteria you might have missed when brushing, you are also gently massaging the gums, which helps promote blood flow in the gums and keeps them healthy. While water picks are an excellent addition to your daily fight against gingivitis and other periodontal diseases, they are incapable of fully removing plaque, which is why Dr. Chad Vanourny and our team at Catawba Valley Dental Care want to remind you to keep brushing and flossing every day.

If you have sensitive teeth or gums and find it uncomfortable to floss daily, water picks are a good alternative to reduce discomfort while effectively cleaning between teeth. Diabetics sometimes prefer water picks to flossing because they don't cause bleeding of the gums, which can be a problem with floss. If you have a permanent bridge, crowns, or other dental restoration, you may find that a water pick helps you keep the area around the restorations clean.

So how do you choose the right water pick?

Water picks are available for home or portable use. The home versions tend to be larger and use standard electrical outlets, while portable models use batteries. Aside from the size difference, they work in the same manner, both using pulsating water streams. A more crucial difference between water picks is the ability to adjust the pressure. Most home models will let you choose from several pressure settings, depending on how sensitive your teeth and gums are. Most portable models have only one pressure setting. If you want to use mouthwash or a dental rinse in your water pick, check the label first; some models suggest using water only.

Please give us a call at our Charlotte office if you have any questions about water picks, or ask Dr. Chad Vanourny during your next visit!
