The grownups in your life encourage you to brush and floss, eat healthy foods, and visit us in the dental office for exams and cleanings. Why? Because we all want to help you prevent cavities.

So you might be wondering, just what are cavities? How do we get them? What do they do to our teeth? How can we prevent them? Let’s talk!

Our teeth need to be strong to bite and chew. That’s why they are protected by a coating called enamel, which is made up of very hard minerals. Enamel is the strongest part of our bodies—stronger even than our bones. But this doesn’t mean nothing can hurt it! And cavities, also called tooth decay, are one of the most common dangers facing our enamel.

So, what are cavities?

A cavity is a hole in your tooth enamel. If your tooth is not cleaned and repaired when a cavity is small, this hole can grow bigger until tooth decay reaches the inside of your tooth. Enamel doesn’t heal when it’s damaged, so you need to see a dentist to make your tooth healthy again.

How do we get cavities?

Bacteria are tiny little germs. Many kinds of bacteria live in our bodies, and some of them are quite helpful. The bacteria that cause cavities are not. These unhelpful bacteria join with our saliva and very small pieces of the food we’ve chewed to make a sticky film called plaque.

Like other living things, the bacteria in plaque need food. They get that food from the foods we eat, especially sugars and starches. As they eat, they change these sugars and starches into acids, and these acids attack the minerals that keep enamel hard and strong.

Because plaque sticks to our teeth, bacterial acids are able to make weak spots in enamel if the plaque isn’t brushed away. If you see a white spot on your tooth, which could mean that your enamel is losing minerals, and getting weaker.

What do cavities do to our teeth?

Over time, weak spots can grow bigger until there’s a hole in the enamel surface. If the cavity in your enamel is small, you might not notice it at first. But cavities can become wider and deeper, and even break through enamel to reach the inside of your tooth.

The inside of each tooth holds pulp, the part of your tooth that keeps it healthy. If tooth decay spreads to the pulp, it can cause more damage and infection, so it’s important to treat a cavity right away.

Dark spots on your enamel, a toothache, pain when you drink something hot or cold or when you bite down—these can be clues that you have a cavity, and you should visit us for an exam.

How can you prevent cavities?

Even better than treating a cavity is preventing one. Let’s make a list of some helpful do’s and don’ts for cavity prevention:

• Do: Feed yourself foods that are good for you.

Foods like milk and cheese and many dark green vegetables have lots of calcium and vitamin D to help keep your enamel strong.

• Don’t: Feed bacteria foods that are good for them.

Sugar and simple starches like potato chips are the kinds of foods bacteria like best, because they are easy to break down. This means more acids to attack your enamel.

This doesn’t mean you should never enjoy a treat! But eating lots of starchy snacks and drinking sugary sodas means more plaque, and more plaque can mean more cavities. If you’re eating something starchy or sweet, it’s a good idea to brush or rinse afterward.

• Do: Brush at least twice a day, for at least two minutes, with fluoride toothpaste.

This is the best way to get rid of plaque, which builds up every day. And fluoride toothpaste even helps make your enamel stronger.

• Don’t: Forget to floss.

Flossing takes a while to learn to do well, but it’s very important. Flossing helps prevent cavities between the teeth and near the gums.

• Do: Visit our Creve Coeur or St. Charles office for exams and cleanings.

Not only will we look for cavities, we’ll let you know the best way to brush and floss so you can get your teeth their cleanest. We even have special coatings called sealants that can protect your teeth from plaque.

• Don’t: Feel bad if you get a cavity!

Some people are more likely to get cavities than others, even when they brush just right and eat healthy foods. If you have a cavity, we can remove decay and repair your tooth with a filling.

And one last thing to do: talk to Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks if you have any questions about the best ways to protect your teeth from cavities. We have lots of suggestions to help you take care of your healthy, beautiful smile!

We want our children to have every advantage, including oral health. That’s why you encourage your child to brush twice a day. You keep the sugary treats to a minimum. You schedule dental exams and cleanings at our Creve Coeur or St. Charles office.

So, how did your child get a cavity? What to do to prevent more tooth decay?

First, don’t feel guilty. Some people are more prone to cavities, even with diligent brushing and flossing. But to make sure children have all the advantages when it comes to preventing cavities, we have some tips which might improve their dental habits.

• Better Brushing

Even for adults, brushing technique can be haphazard! Brushing’s not as effective without covering all the tooth surfaces (inside, outside, and molar tops), holding the brush at a 45° angle, gently brushing the teeth with small strokes, brushing for at least two minutes, and flossing between the teeth at least once a day.

Until children develop the motor skills to brush by themselves (around age six or seven), you can help by monitoring their brushing and flossing. If you like, you can use these four minutes a day for fun as well as dental care by playing music, awarding stickers, using an app with entertaining timers, or having your child mirror your brushing habits as you brush together.

And do make your child’s life easier with the right tools. Brush heads should be small enough to fit in little mouths comfortably, and bristles should always be soft. Floss, too, should be soft and flexible. Don’t forget to retire your child’s brush after three or four months—bristles start to fray and won’t clean effectively.

• Sealing the Deal

Ask about dental sealants. This treatment provides a protective coating for your child’s molars. Cavities are so common in molars because the tops of these teeth are quite uneven. Food particles and plaque are trapped in grooves where brushes have a hard time reaching.

The sealant process is a simple and safe one. Healthy teeth are cleaned and dried, an etching solution prepares the tooth surface, a thin coat of sealant is applied, and the coating is hardened under a curing light.

Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks might recommend sealants when your child’s first adult molars erupt. Enamel takes a while to develop its full strength, so new molars are especially vulnerable to cavities. Sealants typically last from three to five years, and studies have shown a dramatic reduction in cavities when teeth are treated with sealants.

• Fluoride Helps Prevent Cavities—in Two Ways!

Fluoride helps strengthen enamel in developing teeth. Because many communities have fluoride available in their water systems, your child gets the benefit of this natural mineral.

If you’re providing your child with fluoride toothpaste, you’re helping prevent cavities in the teeth, which have already erupted. The acids from oral bacteria weaken the mineral structure of enamel, which is the first step in forming a cavity. Fluoride helps repair weakened enamel in a process known as “remineralization.”

Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks can let you know the amount of fluoride that is right for your child, including how much or how little fluoride toothpaste to use, a prescription supplement if your water doesn’t contain fluoride, or the application of a fluoride treatment directly to your child’s teeth.

• Avoid Tricky Treats

Some treats are much better than others. We’re not talking taste, though. When it comes to dental health, texture and time are more important.

When your child enjoys a plain chocolate bar, saliva helps wash away sugary food particles. Sticky candies and starches, like caramels and potato chips, are a “stickier” problem. They cling to enamel, providing lots of sugar as fuel for cavity-creating bacteria. Similarly, drinking a soda with lunch (not every day, of course!) provides a short exposure to sugars. Sipping sodas throughout the day is like bathing teeth in sugar for hours at a time.

To eliminate some of the treats bacteria love, choose snacks with an eye to how they affect teeth throughout the day, and teach your child to brush or rinse with water after eating.

• Schedule Regular Dental Exams and Cleanings

Most children should be visiting Dentistry for Children twice a year, even during the baby teeth years. Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks will monitor your child’s primary teeth and developing teeth and bite. And a professional cleaning removes built up plaque that even the most dedicated brusher might miss.

If you have any concerns about cavities and their prevention, Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks will have suggestions tailored to your child’s individual needs. Us working together to make sure your child has a healthy, confident smile? That’s a partnership that will provide lifelong advantages!

“Non-nutritive sucking behavior”? That’s a mouthful—literally! This term describes behaviors such as thumb sucking and pacifier use, which are generally healthy, self-soothing activities for infants and toddlers. But, if followed too long, this comforting habit can have uncomfortable consequences for your child’s dental health.

When children are nursed or bottle-fed, placing a nipple in the mouth helps trigger the sucking reflex, enabling the flow of milk or formula. This is called nutritive sucking, because nourishment is the goal. The sucking reflex is so essential that it develops even before birth. And while the purpose of this reflex is nourishment, it provides other benefits as well.

For small children, sucking can be a comfort mechanism to help them cope with stressful situations and calm themselves. That’s why you often see your child sucking on a pacifier, toy, thumb, or fingers when feeling overwhelmed or tired. Non-nutritive sucking behavior, or NNSB, refers to these habits: sucking without nutritional benefit.

Such habits are extremely common in young children. Most children stop sucking their thumbs or pacifiers between the ages of two and four, and often even earlier. But if your child hasn’t, it’s a good idea to talk to Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks about easing your child away from this familiar habit before the permanent teeth start to arrive.

Why? Because when sucking behavior lasts too long, it can have orthodontic consequences. Just as the gentle pressure of braces or aligners can help shift teeth and jaws into the proper alignment, the pressure from sucking thumb and pacifier can push growing teeth and jaws out of alignment.

• Studies have shown a clear link between NNSB and malocclusions, or bite problems. These include overjets (protruding upper teeth), open bites (where the upper and lower teeth don’t make contact when biting down), and crossbites (where one or more upper fit teeth inside lower teeth).
• As young bones are still growing, prolonged, vigorous sucking can affect the shape and size of a child’s palate and jaw.
• When the teeth are pushed out of alignment, difficulties with pronunciation, such as lisps, can develop.

Sucking habits can be difficult to give up. If your child is still self-comforting with the help of thumb or pacifier past age three, and certainly if you’ve noticed any changes in teeth or speech, there are several gentle, positive steps you can take to protect your child’s dental health.

• Talk to Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks about strategies for weaning your child from pacifier and thumb, as well as possible comforting substitutes. Your healthcare team can offer suggestions for making this transition as easy as possible for your child—and for you!
• Discuss recommendations you’ve found in books or online which might be a good match for your child’s personality. Whatever you decide on, whether it’s a gradual phasing out, small rewards, a goals chart, or any other method, use positive reinforcement and plenty of encouragement.
• Set easy goals at the beginning, such as going thumb-free while playing a game, or enjoying a favorite video, or any stress-free activity, to give your child a feeling of accomplishment to build on.
• Be proactive with orthodontic health. One good idea is to schedule an orthodontic visit when your child is around the age of seven—or earlier if you notice problems with tooth alignment, speech, or bite.

Thumb sucking and pacifier use can be important, instinctive sources of comfort for very young children. And, of course, NNSB is not the only cause of childhood malocclusions. Many bite problems are genetically based and/or affected by the size and shape of your child’s teeth and jaws.

But eliminating the preventable oral health problems caused by prolonged non-nutritive sucking behaviors—that’s an opportunity we can’t afford to pass up. After all, wanting to ensure healthy, confident smiles for our children is instinctive parental behavior!

The grownups in your life want you to have healthy teeth. That’s why they remind you to brush and floss, make you tooth-friendly meals, and take you to see the dentist regularly, at an office designed just for you. You’ve been visiting Dentistry for Children for a while now, so you know all about checkups and cleanings.

At every dental exam, Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks will look at your teeth very carefully, checking not just the outside of your teeth, but around and behind your teeth as well. (That’s what those little mirrors are for.) You might have X-ray pictures taken to show the inside of your teeth. In all these ways, we make sure your teeth are healthy, inside and out.

You expect all these things at a dental checkup because you’re used to them. When you hear that you have a cavity, you might be worried. After all, if you’ve never had a cavity before, you don’t know what to expect. And sometimes not knowing is a little scary. So let’s talk about what a cavity is, and how your dentist can help make your tooth healthy again if you need a filling.

• What’s a Cavity?

Teeth are covered with a very hard white coating called enamel. Enamel is the strongest part of our bodies, even stronger than our bones. But when we eat too many sugary foods, or don’t brush the way we should or as much as we should, or even just because of the way some people’s bodies work, our enamel can be hurt by cavities.

A cavity is a hole in your tooth enamel. These holes are made by the bacteria in plaque, which turn sugars into acids. This is why it’s important to brush carefully to get rid of plaque, and to watch how much sugar we eat. It’s not just people who like sugar—bacteria do, too!

The acids bacteria create attack our enamel and make it weaker. If the enamel gets too weak, a hole will start to form. This is what we call a cavity.

• How Do You Know You Have a Cavity?

Maybe you came to our Creve Coeur or St. Charles office because you have a toothache, or it hurts when you eat something hot or cold. Those are often clues that you have a cavity.

But small, early cavities don’t always bother us. That’s why regular checkups are so important, and why Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks will look carefully at each tooth to make sure that it’s healthy.

• Getting Ready

Dr. Varble, Dr. Dill, Dr. Wong, and Dr. Parks might give you some medicine to make sure you don’t feel uncomfortable while your tooth is being repaired. The area around your tooth will get numb, which means you won’t feel anything while we work.

• Removing Decay

There are different ways to remove decay from your tooth. Some can be noisy, and some are quiet.  If noise bothers you, let your dentist know—there are ways to cover up annoying sounds.

After the decay has been removed, it’s time to clean your tooth. This makes sure that no germs or bacteria are still around when your tooth is filled.

But after all the decay is gone, you’ll still have a little hole in your tooth. That’s why the next step is . . .

• Filling Your Tooth

Since a hole in your tooth enamel makes it weaker, this hole needs to be filled up to make your tooth strong again—that’s why it’s called a “filling.”

There are different kinds of fillings, and your dentist will tell you which one is best for your tooth. A molar, one of the big teeth in the back of your mouth, needs a strong filling for all the work it does chewing food. Your dentist might use a metal filling to help your molar do its job. If you have a cavity in one of your front teeth, you might get a tooth-colored filling. This filling is made to match the color of your enamel, so no one can see the filling when you smile.

• After Your Filling

All done! In just a little while, the area around your tooth won’t be numb anymore, and we will let you know when you can eat and drink regular foods again.

If you do your best to keep your teeth healthy, you can look forward to cavity-free checkups in the future. But when you need a filling, or if you have a tooth which needs another kind of treatment, we are here to help you make sure your happy smile is a healthy smile!
