Snacks can taste good and give your child’s energy a boost, but they can also be bad for teeth. Sugary, sticky snacks, such as candy, cookies, and snack cakes can lead to tooth decay if eaten regularly between meals. Still, there are plenty of fun snacks for healthy teeth.

The trick when selecting snacks is to avoid too many added sugars and refined carbohydrates that stay on the teeth and give bacteria a chance to ferment and produce acid from them, which can lead to tooth decay. In addition, snacks should provide nutrients to support a healthy mouth. These are five fun snacks you can feel good about giving to your child.

1. Yogurt and cereal.

Yogurt contains calcium, which is an essential mineral for strong and healthy teeth. Select plain yogurt or yogurt flavored with real fruit, rather than flavored yogurt that is sweetened with added sugar. We recommend choosing a whole-grain cereal, which is less likely to lead to dental caries. Choose a low-sugar or unsweetened cereal to avoid accidentally making the snack as sugary as a candy bar.

2. Tuna and whole-wheat crackers.

Canned tuna contains vitamin D, which is an essential vitamin for helping your body absorb and use calcium. Whole-wheat crackers are natural sources of antioxidants for a strong immune system, and they’re lower in refined carbohydrates than white crackers.

3. Bell pepper strips and hummus.

Red, yellow, and green bell peppers are excellent sources of vitamin C, which is an antioxidant. Vitamin C is also a good choice for supporting regeneration or maintenance of healthy gum tissue. Vitamin E is another antioxidant, and it also supports a healthy immune system. A strong immune system is protective against infections, such as bacterial infections associated with gum disease.

4. Turkey and cheese roll-ups.

Turkey is carbohydrate-free, so it doesn’t leave residues of sugars on teeth for bacteria to ferment. Lean ham is another good choice. Low-fat cheddar, mozzarella, or Swiss cheese is a good source of calcium as well as protein. For a more substantial snack that’s still low in carbohydrates and sugar, add a few celery sticks.

5. Peanut butter and carrots.

Peanut butter is another source of vitamin E. Carrots provide vitamin A, which is essential for a strong immune system. You can also substitute cauliflower or broccoli florets for the carrots, and ranch dressing for the peanut butter, and still have a snack that’s fun to eat and good for your child’s teeth.

Perhaps you’ve heard your friends talking about dental sealants, and how well they prevent cavities. And as soon as your child’s permanent molars come in, you absolutely plan to make an appointment at our Creve Coeur, MO and St. Charles, MO office for this treatment. But should you also be concerned with your child’s baby teeth? Could they benefit from sealants too?

Even though those beautiful baby teeth are going to be replaced with permanent teeth, they should still be protected. Primary teeth help with speech development, enable your child to develop proper chewing and eating habits, and serve as place holders so that permanent teeth can erupt in the correct place. That’s why you’ve been so careful to help your child brush and floss twice daily, and make regular visits to our office for exams and cleanings.

But some teeth are just harder to keep clean with regular brushing than others. Primary molars, just like permanent ones, have depressions and grooves on the chewing surfaces. These grooves collect bacteria and food particles that are hard for bristles to reach, providing a perfect opportunity for cavities to develop in those little molars.

Cavities are not the only problem which can affect primary teeth. Because baby teeth have thinner layers of protective enamel, a cavity can actually reach the pulp (the center of the tooth) more quickly, leading to pain and potential infection.

While baby teeth can be treated, with fillings, restorations, and even stainless steel crowns, preventing tooth decay is always our first, best choice. And dental sealants are recommended by the American Academy of Pediatric Dentistry and the American Dental Association as one of the most effective ways to prevent cavities in both baby teeth and adult teeth.

Dental sealants are safe and effective.  Sealants are thin coatings (usually a plastic resin or other dental material) that cover a molar’s grooves and depressions, making it impossible for bacteria and food particles to collect there. Applying them is a simple, pain-free process.

Each tooth will be examined first. If we find any signs of decay starting, we will gently treat that area before applying the sealant. After the tooth is cleaned and dried, an etching solution will be brushed on to the surface area being sealed. This etching roughens the surface so that the sealant will hold to the tooth more effectively. A thin coat of the sealant is then painted on and hardened under a curing light.

That’s all there is to it! Sealants typically last from three to five years, and some last even longer. Keep up your regular careful brushing and flossing, and we will monitor the condition of the sealants at each exam.

Talk to Dr. Varble, Dr. Appelbaum, Dr. Dill and Dr. Wong about dental sealants. We’ll let you know if your child can benefit from the procedure even before those baby teeth give way to permanent ones. It’s never too early to prevent tooth decay!

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. Varble, Dr. Appelbaum, Dr. Dill and Dr. Wong 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 Creve Coeur, MO and St. Charles, MO office so we can take the proper action to protect the health of your mouth.

Pediatric dentists strive to make your children’s visits welcoming and worry-free, and, we want the same for you! Ask us about any questions you might have. We are happy to explain procedures, equipment, and sedation options so you know just how safe and comfortable your child’s experience can be. And if X-rays are a concern, we can put your mind at ease here as well.

What Exactly Are X-rays?

Sometimes parents feel reluctant about the process of imaging because X-rays are a kind of radiation. But the fact is, radiation is all around us. We are exposed to radiation naturally from our soil and water, sun and air, as well as from modern inventions such as cell phones, Wi-Fi, and air travel.

Why is radiation so common? Because matter throughout the universe constantly gives off energy, and the energy that is emitted is termed radiation. This radiation takes two forms—as particles (which we don’t need to consider!) and as traveling rays. This second type is known as electromagnetic radiation, created by photons traveling in regular waves at the speed of light.

We are exposed to electromagnetic radiation every day, because, whether we can see them or not, these different wavelengths and frequencies create various forms of light. Radio waves, microwaves, infrared, visible, and ultraviolet light, X-rays, and gamma rays are all part of the electromagnetic light spectrum.

Different types of radiation on this spectrum have different wavelengths and different frequencies, and produce different amounts of energy. Longer wavelengths mean lower frequencies and less energy. Because X-rays have shorter wavelengths and higher frequencies than, for example, radio waves and visible light, they have more energy.

How Do Dental X-rays Work?

An X-ray machine produces a very narrow beam of X-ray photons. This beam passes through the body and captures images of our teeth and jaws on special film or digital sensors inside the mouth (intraoral X-rays), or on film or sensors located outside the mouth (extraoral X-rays). These X-ray images are also known as radiographs.

Why are X-rays able to take pictures inside our bodies? Remember that higher energy we talked about earlier? This energy enables X-rays to pass through the softer, less dense parts of our bodies, which are seen as gray background in a radiograph. But some substances in our bodies absorb X-rays, such as the calcium found in our bones and teeth. This is why they show up as sharp white images in radiographs. 

There are different types of common dental X-rays which are used for pediatric exams, including:

• Bitewing X-rays, which are used to check on the health of the back teeth.
• Periapical X-rays, which allow us to look at one or two specific teeth from crown to root.
• Panoramic X-rays, which use a special machine to rotate around the head to create a complete two-dimensional picture of teeth and jaws.

Why Do We Need X-rays?

If all of our dental conditions were visible on the surface, there would be no need for X-rays. But there are many conditions that can only be discovered with the use of imaging—infection, decay, or injuries, for example, can show up as darker areas in the teeth or jaws. Among their many diagnostic uses, X-rays can help us find:

• Cavities between teeth
• Damage to the tooth’s pulp which might require root canal treatment
• Injuries to teeth or roots after trauma
• Abscesses, tumors, or other conditions that might be causing swelling or pain
• Unusual position or development of the teeth before and as they erupt
• Alignment and development of wisdom teeth

X-rays can also serve an important preventative role, by discovering small problems before they become major ones.

How Do Dentists Make Sure Your Child’s X-rays Are as Safe as They Can Be?

First of all, the amount of radiation patients are exposed to with a dental X-ray is very small. In fact, a set of bitewing X-rays exposes us to slightly less than the amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Dr. Varble, Dr. Appelbaum, Dr. Dill and Dr. Wong and our team are committed to making sure young patients are exposed to as little radiation as possible.

Radiologists, the physicians who specialize in imaging procedures and diagnoses, recommend that all dentists and doctors follow the safety principal known as ALARA: “As Low As Reasonably Achievable.” This means using the lowest X-ray exposure necessary to achieve precise diagnostic results for all dental and medical patients.

The guidelines recommended for X-rays and other imaging have been designed to make sure all patients have the safest experience possible whenever they visit the dentist or the doctor. We ensure that imaging is safe and effective in a number of ways:

• We take X-rays only when they are necessary.
• We provide protective gear, such as apron shields and thyroid collars, whenever needed.
• We make use of modern X-ray equipment, for both traditional X-rays and digital X-rays, which exposes patients to a lower amount of radiation than ever before.
• We set exposure times based on each child’s size and age.

X-rays play an important part in helping us make sure your child’s teeth stay their healthiest. If you have any concerns, contact our Creve Coeur, MO and St. Charles, MO office. When it comes to making sure you’re comfortable with all of our procedures, including any X-rays that might be necessary, we’re happy to give you all the inside information!
