When Is a “Cavity” Not a Cavity?

April 29th, 2020

Is this a trick question? After all, you and your family probably already know quite a lot about cavities:

  • It all begins when bacteria-filled plaque sticks to teeth and starts to attack enamel. How?
  • Because the bacteria in plaque use the sugars and other foods we eat to produce acids.
  • These acids gradually weaken teeth by dissolving minerals that help make up our enamel (a process called demineralization).
  • Over time, a hole, or cavity, develops in the tooth surface.
  • Left untreated, bacterial decay can spread to the inside of the tooth, creating a more serious cavity.

Dr. Varble, Dr. Appelbaum, Dr. Dill and Dr. Wong might discover an unexpected cavity at a regularly scheduled dental exam at our Creve Coeur, MO and St. Charles, MO office, but there are also some symptoms that should have you calling for an appointment. A cavity can cause sensitivity when eating something hot or cold, or it can be painful, or you might even notice visible discoloration or damage to the tooth surface.

So, if your child has any of these symptoms, it’s a cavity, right? It might be—but it might not. Sometimes, because the symptoms are similar, what we suspect is a cavity is really enamel erosion.

The bacteria-created acids weaken enamel. But it’s not just bacteria that subject our teeth to acids. Acidic foods are one of the leading causes of tooth erosion.

And while we expect damage from a lifetime of acidic foods and beverages to catch up with us as we age, the fact is that erosion is becoming a problem even for young children. How is this possible? Let’s look at some food chemistry.

Our normal saliva pH level is around a 7, which is neutral. Any number lower is acidic; any number higher is alkaline. Acidic foods have a low pH (the pH of lemon juice, for example, measures between 2 and 3), and can reduce our normal, neutral pH level. When saliva pH levels drop to 5.5 or lower, tooth enamel starts to demineralize, just as it does when exposed to the acids from oral bacteria.

Regularly snacking on citrus and other acidic fruits, fruit juices, flavored drinks, sour candies, and other acidic foods can cause enamel erosion. Especially erosive are sports drinks, energy drinks, and colas, because they contain some combination of citric acid, phosphoric acid and/or carbonation.

So, when might you suspect enamel erosion? Your child might be sensitive to hot or cold foods, or feel pain, or even have noticeable enamel loss or pitting. Even though these symptoms may not have been caused by plaque and bacteria, acidic erosion from our diets leaves weakened enamel just as vulnerable to cavities and decay.

How to avoid erosion?

  • Serve acidic foods sparingly, or as part of a meal. This helps our saliva pH stay in the neutral zone.
  • Balance acidic foods with low-acid choices to neutralize acids and restore a normal pH balance. For example, mix those acidic berries with a banana.
  • Use a straw! These are not only fun, but this simple solution keeps erosive drinks from bathing young teeth in acids.
  • Encourage your child to drink water instead of an acidic beverage, or drink it afterward to rinse acids away. The pH of pure water? A perfect, neutral 7. And by using tap water instead of bottled water, you’ll be providing fluoride, which helps strengthen enamel.
  • What about brushing right after eating or drinking something acidic? Ask Dr. Varble, Dr. Appelbaum, Dr. Dill and Dr. Wong if your child should rush for the brush. We may recommend waiting 30 minutes or so after an acidic treat to give the teeth time to remineralize. Otherwise, brushing might cause more wear and tear on enamel.
  • Finally, while foods are often the source of acid erosion, medical conditions can cause erosion as well. Talk to us about ways to minimize erosion while addressing these medical needs.

Be proactive. Ask your Dr. Varble, Dr. Appelbaum, Dr. Dill and Dr. Wong about healthy drinks and snacks for healthy teeth. Make sure to keep on top of brushing and flossing, and stick with fluoride toothpastes. And visit our Creve Coeur, MO and St. Charles, MO office regularly for exams and cleanings.

There’s really no trick to it—preventing enamel erosion helps keep your child’s teeth structurally strong and cavity-free for a lifetime of beautiful and healthy adult smiles.

The Perks of Dairy

April 22nd, 2020

We all remember hearing this: “Finish your milk, it’s good for your bones!” If you have kids of your own now, you may catch yourself repeating many of the things you were told growing up.

Though parents occasionally exaggerate to get their kids to do certain things (such as eat veggies or behave), they’re spot-on about milk. Consuming enough dairy every day is crucial for growing children, because this can set them up to have strong and healthy teeth for the rest of their lives.

To understand the effects of dairy on your child’s teeth, take a look at tooth structure. Think of it in terms of layers: the innermost layer is the living tissue, the second layer is dentine (a calcified tissue), and the final one is the enamel, aka the white part of the tooth. Keep in mind that 96 percent of your enamel is made up of minerals like calcium.

Now, milk and other dairy products are excellent sources of calcium, so when you consider the need to build strong enamel for the first line of defense, it’s easy to see the connection between dairy and good dental health. When your son or daughter consumes dairy products, the body sends the incoming calcium to growing bones, which includes teeth.

This makes children’s teeth and bones stronger all around. Growing youngsters who do not get enough dairy in their diet are at risk for improper tooth development, as well as other dental problems.

According to the U.S. Department of Agriculture, children under the age of eight should be receiving at least two and a half cups of dairy per day. Children older than eight require three full cups, which is the same amount recommended for male and female adults.

If you’re looking for easy ways to incorporate dairy into your children’s diet, try snacks like cottage cheese, a milk-based smoothie, yogurt, cheese sticks, non-fat milk, and fruit parfaits, to name a few. Once you get a feel for what they like most, furnishing the ideal amount of dairy to their diet should be no problem!

If you’re concerned about your child’s teeth or have questions about a healthy diet, don’t hesitate to contact our Creve Coeur, MO and St. Charles, MO office and ask a member of our team.

Just What Is Plaque?

April 15th, 2020

When you were younger, and you brushed your teeth without any help for the first time, it was a big step. It meant you’d learned the right way to brush to keep your teeth and gums healthy. But why does brushing help keep you healthy? Let’s talk about plaque!

  • What Is Plaque?

Plaque rhymes with “attack,” and that’s just what it does to your teeth. If you don’t brush for a few days (which is a bad idea!), plaque is the reason for that fuzziness you feel when you run your tongue over your teeth.

If your teeth feel fuzzy, that means that plaque has been building up for a while. But how does it begin?

Plaque is made up of saliva, bits of food, other liquids, and tiny little organisms called bacteria. While most of the bacteria in our bodies don’t bother us—and some even help us—the bacteria in plaque are not so helpful.

Plaque starts with a type of bacteria that stick to the teeth, loosely at first, and then more strongly. Within hours, they join with saliva, bits of food, and other bacteria and bacterial products to make a very sticky film. This film is plaque.

Why is it so important to brush plaque away every day? As Dr. Varble, Dr. Appelbaum, Dr. Dill and Dr. Wong will tell you, plaque can cause cavities and hurt your gums.

  • How Does Plaque Cause Cavities?

Bacteria are like us—they need food. The bacteria in plaque especially like the sugars we eat. (That’s why you shouldn’t have too much junk food or candy in your diet.) Bacteria change these sugary building blocks into a kind of acid, and because plaque is sticky, the acids stay on your teeth.

These acids breaks down the enamel, that hard coating which covers teeth. Tiny weak spots can grow and become holes in the enamel. We call these holes cavities, and your dentist can repair them by cleaning away the decay and putting a filling in your tooth to protect it.

But it’s best to prevent cavities from ever starting by brushing and flossing. Even though plaque is sticky, it is easy to brush away when you do it every day.

  • How Does Plaque Hurt Your Gums?

The gums surround our teeth and help protect them, but they are also delicate. When plaque builds up, it can irritate your gums.

You might notice that your gums get red, feel sore when you brush, or look puffy. You might have bad breath that doesn’t go away. All these are signs that your gums are reacting to the plaque around them.

The good news is that careful brushing and flossing can usually fix these problems. Talk to Dr. Varble, Dr. Appelbaum, Dr. Dill and Dr. Wong about taking good care of your gums.

  • Can We Fight Plaque?

Yes! From the time you were small and learned how to brush, you’ve been learning how to fight plaque.

  • Brush at least twice a day for two minutes, and be sure to brush all around each tooth and the gums.
  • Floss to remove plaque from where it hides between the teeth and near the gums.
  • Visit our Creve Coeur, MO and St. Charles, MO office for a cleaning, to remove plaque from hard-to-reach places and to learn the best ways to brush and floss.

As soon as you finish brushing, plaque starts to build up again. But no need to worry! Keep brushing, flossing, and visiting us for regular cleanings, and all your careful work will be rewarded will a beautiful, healthy smile.

Mouthguard Protection

April 8th, 2020

Let’s talk about mouthguards and night guards—two crucial appliances that protect your child’s teeth and jaw.

We could talk about how important a mouthguard is when your family leads an active life. Mouthguards protect teeth, delicate mouth tissue, and jaws from accidents and impacts. 

Or if someone in the house grinds his or her teeth at night, waking up every morning with tooth or jaw pain, we can talk about how a night guard can be a quality-of-life-saver.

But we’re not going to talk about any of these important topics today. Instead of looking at how a guard protects your child, today we’re going to look at how you can help children protect their mouthguards.

If you want their guards to last longer, work better, and stay (and smell!) cleaner, some basic tips make all the difference. Here are some important rules to share with your child.

  • Keep your guard clean.

This can’t be stressed enough. Without a good cleaning routine, your guard can become discolored, develop an unpleasant odor, and even cause illness. Not very appealing, right? Happily, keeping mouthguards and night guards clean isn’t difficult.

When you wear your guard, whether during daytime activities or through the night, the same plaque that is present in your mouth makes itself at home your guard. And when your night guard or mouthguard is in its case, that dark, moist environment makes it a perfect breeding ground for all kinds of bacteria, viruses, and fungi.

As soon as you take your mouthguard out, rinse it off. Brush with a soft toothbrush to remove all the plaque, saliva, or food debris that might be lingering in your appliance. (If you are on the playing field, in the park, or at some other inconvenient location, rinse it and brush as soon as you can.) Toothpaste can help get your guard its cleanest, but can be too abrasive for some appliances.

Once you’ve cleaned it, let your guard air dry in a clean spot for about 30 minutes. Air drying helps prevent bacterial growth. After your guard has dried, return it to its case.

Once a week, you might need to give your guard a good soak in a mouthwash or other dental cleaning solution.

Since cleaning instructions can be different depending on which type of guard you have, be sure to follow our instructions if you have a custom guard, or follow the manufacturer’s cleaning instructions if you have a store guard.

  • Keep it safe.

When your guard isn’t in your mouth, it should be in its case. Floating loose on the bathroom counter or tumbling around in your gym bag puts your guard at risk for breakage and bacteria.

And don’t forget to clean your case thoroughly every few days and air dry it as well. Bacteria, viruses, fungi, mold, and other unwelcome guests can collect in your case, too.

  • Keep it only as long as it’s in good condition.

You can purchase mouthguards from sporting or drug stores, or Dr. Varble, Dr. Appelbaum, Dr. Dill and Dr. Wong can make a mouthguard or night guard designed to fit your teeth perfectly. These appliances are made to be strong and durable, but they’re not indestructible. Over time they can wear down or become damaged, especially if you treat them carelessly.

Bacteria can lurk in dents and cracks, and you can cut your mouth on rough, sharp, or broken edges. But if your guard isn’t fitting properly, don’t resort to self-help! Trying to repair, reshape, or trim your appliance yourself is not a good idea, because it might affect its fit and protective ability.

Any sign that your guard isn’t fitting properly or shows signs of wear and tear could mean it’s time for a replacement. You can replace a store model, or ask our Creve Coeur, MO and St. Charles, MO team about repairing or replacing your custom guard. A mouthguard that doesn’t fit, doesn’t keep you safe.

Take care of your guard, and it will take care of you. The reward for the small amount of time and effort you put into caring for your mouthguard or night guard is a smile that will last you for a lifetime. That’s a benefit we can talk about all day!
