A strong, healthy smile is built on a strong, healthy foundation. Let’s take a moment to explore just what creates that foundation—your roots.

The Root of the Matter

The visible part of your tooth is called the crown. And while we spent the great majority of our time thinking about what goes on above the gum line—brushing, flossing, whitening, sealing, preventing cavities—the roots, the parts of the teeth below the surface, are also essential to our dental health.

• What’s inside the root?

The inside of each tooth holds pulp, which is living tissue made of nerves, blood vessels, and connective tissue. The nerves in the pulp allow us to feel pain when a tooth is damaged, decayed, or infected. Tiny blood vessels provide oxygen and nutrients to the cells.

The inside of each root also contains pulp, located in one or more root canals. These canals are small tunnels that travel from the pulp chamber to the tip of each root. Nerves and blood vessels connect pulp tissue to the nervous and circulatory systems in the body, entering and exiting the tooth from very small openings in the root tip.

• What’s outside the root?

On the outside, while roots look like crowns, they’re covered with a different protective surface. Roots are covered by cementum rather than enamel. This is a hard tissue, but not as hard as enamel. But cementum has another advantage—it not only helps protect our teeth, it helps them stay anchored in our jaws. (More on this below.)

• How many roots are we talking about?

The number varies, not just depending on the tooth, but depending on the individual. Most adults have 32 adult teeth: eight incisors, four canines, eight premolars, eight molars, and four wisdom teeth, or third molars. Because the number of wisdom teeth can range from four to zero, though, that total can be smaller.

Rooted to the Spot

The reason that you can rely on your teeth for a lifetime of chewing, biting, and grinding food is the fact that they’re so securely anchored in the jaw.

• Alveolar bone in the jaw contains a socket for each tooth.

• A thin layer of connective tissue called the periodontal ligament lines the socket and surrounds each root. It’s filled with fibers that attach to the root’s cementum covering and to the alveolar bone, holding the tooth securely in place.
• The periodontal ligament not only anchors the tooth, it cushions it from the daily pressure of biting and chewing.
• Finally, the gums surround the teeth and bone, protecting them from bacteria and plaque.

Even though this design is very secure, there are situations where the root becomes vulnerable. In that case, you should see Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying at our Hiawatha, IA office right away. Our goal is for you to keep your teeth healthy and strong, and for a lifetime!

It’s the holiday season! With so much to do and so much going on, you want to be at your best. We have some ideas to help make your season bright with a few easy tips for a healthy smile.

• Keep Your Smile Merry and Bright

There’s a lot going on during the holidays. Visiting friends. Traveling to see family. Parties and get togethers. With all the enjoyable festivities on your holiday schedule, you might be tempted to overlook brushing or flossing. But, please don’t!

Many of our favorite holiday traditions and activities are centered around sharing good company, good cheer—and good food.

Indulging in more treats throughout the day, especially sugars and simple carbs, provides more fuel for the bacteria in plaque. These bacteria produce acids that weaken tooth enamel—the first stage of tooth decay. Plaque buildup also irritates the gums, causing swelling, redness, pain, bleeding, and chronic bad breath.

How to avoid these not-so-jolly consequences? Make time in your holiday schedule for dental care! Brushing twice a day for two minutes and flossing once each day removes plaque buildup and helps prevent cavities and gum disease.

• Holiday Snacks—Naughty or Nice?

We’re no Scrooges—enjoying holiday treats is one of the ways we celebrate. But since we’re trying to prevent a plaque buffet of sugar and simple carbs, it’s a good idea to add some healthier foods to the mix.

Whether it’s platters of snacks around the game table or a stylish hors d’oeuvre array, don’t forget to add nutritional, dental-friendly items to your plate. Options such as fresh fruits and vegetables, cheeses, nuts, and whole grain breads and crackers are great partners for more indulgent selections because they’re lower in added sugars and provide vitamins and minerals to strengthen teeth and gums.

And from the candy bar? Hard candies and candy canes make our naughty list because they take a long time to dissolve while bathing your teeth in sugar. So do caramels, toffees, and gumdrops, which stick between teeth and gums. Soft chocolates? A much nicer choice, because they are more easily rinsed away by saliva or a drink of water. Which leads us to . . .

• A Toast to Your (Dental) Health!

The holidays offer some of our favorite seasonal beverages. But spiced lattes, mochas, and hot chocolate can be full of sugar.

The answer? Enjoy in moderation, and enjoy with a glass of water. Water washes away sugars, neutralizes acids, helps increase saliva flow for tooth and gum health, hydrates, and, when it’s fluoridated, protects and repairs your enamel. That’s a lot of gifts in one convenient package!

• Dashing through the Snow?

If you’re taking to the slopes, or the hills, or the rink for a little holiday exercise, don’t forget to protect your teeth and mouth. It’s not just sports like football and hockey that cause dental injuries—it’s any sport where you can fall or make contact with someone or something.

If you don’t have a mouthguard, they’re available at sporting goods stores in stock sizes or models that can be molded to your teeth. A custom mouthguard from our Hiawatha, IA office is more comfortable, fits better, and protects you better. This is a perfect gift to give yourself so you can take advantage of all those cold weather sports with confidence.

We all look forward to holiday surprises—but not when they take the form of cavities, gum disease, or dental injuries! In the flurry of holiday activities, keep up with your regular dental care, and you’ll be looking forward to a new year filled with happy and healthy smiles.

You’re all set for your happy morning and nighttime ritual. You’ve provided your son with his favorite action hero toothbrush and your daughter with her favorite flavored toothpaste. You’ve gotten them into the healthy habit of two minutes of brushing twice each day. You’ve introduced them to flossing. You have favorite brushing songs! Stickers! Gold stars! And, best of all, you’re teaching great brushing techniques.

Kids need the same basic brushing tools and skills as adults. What makes for the best cleaning?

Find the right brush

No matter how cute—or heroic—the brush, it needs to have soft bristles to protect enamel and delicate gum tissue. The head should be a perfect fit for your child’s mouth. And if the handle is easy to grip and hold, you have a winner.

Find the right toothpaste

The bubblegum flavor might appeal to your child, but it’s the fluoride that helps to prevent cavities. Talk to us about the right time to start using fluoride toothpaste and the right amount for your child’s brush.

Teach your child the angles

If your child is too young to brush alone, start geometry lessons early. Holding the brush at a 45-degree angle toward the gums will clean bacteria and plaque from the tooth surface and the gum line. And don’t forget the chewing surfaces and the insides of the teeth. When your child begins brushing on her own, coach her as she learns the best way to clean all the surfaces of her teeth.

Easy does it

Teeth and gums should be massaged, not scrubbed. Brushing too hard can damage not only tender gum tissue, but even your child’s enamel.

Learn to let go

No matter how comfortable and appealing the brush, after three or four months, it’s time for a change. Frayed bristles don’t clean as effectively, and making up for it by brushing harder isn’t the answer (see above). Also, toothbrushes can build up quite a collection of bacteria over time (see below), so a fresh brush is a must!

Everything in its place

A toothbrush should dry thoroughly between uses without touching other brushes. Placing a brush in a plastic container doesn’t let it dry and encourages bacterial growth. And a toothbrush needs its own space—touching toothbrush heads means sharing toothbrush bacteria. The best way to keep toothbrushes as dry and as germ-free as possible is to store them upright, without touching other brushes, in a clean, well-ventilated area.

Rinse and repeat

Your child should rinse his toothbrush before and after using it, and be sure to rinse his mouth as well. That should get rid of any leftover food particles brushing has removed.

Finally, keep up the good work! As you teach your child proper brushing techniques, and make sure she uses them as she grows, you are preparing her for a lifetime of great checkups with Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying at our Hiawatha, IA office. Give yourself a gold star—you’ve earned it!

Fluoride has been one of the great game-changers in children’s dental health. Drinking fluoridated water. Using fluoride toothpaste. Scheduling fluoride treatments. All of these child-friendly dental habits help prevent cavities and strengthen tooth enamel.

And we adults enjoy the benefits of fluoride as well. Drinking fluoridated water. Using fluoride toothpaste. If only we hadn’t outgrown fluoride treatments… or have we? Time to have an adult conversation about fluoride treatments!

• To Start, Some Dental Chemistry

The enamel in our teeth is largely made of calcium and phosphate ions. These elements combine to form hydroxyapatite, the mineral crystals that make teeth and bones so hard and strong. But enamel isn’t indestructible. The oral bacteria in plaque create acids that cause demineralization, stripping away calcium and phosphate ions. This leaves the tooth surface weakened and vulnerable to decay.

Our bodies have a way of compensating for demineralization. Saliva is filled with calcium and phosphate ions that restore lost minerals. This balancing act goes on every day. When conditions in the mouth are too acidic, however, remineralization can’t take place as effectively. Here’s where fluoride is so beneficial.

• Why Fluoride?

First, because fluoride helps remineralize. Fluoride works on the surface of the tooth to attract the calcium and phosphate ions in our saliva, restoring them to our teeth. Even better, it joins with these ions to create fluorapatite. Fluorapatite crystals are larger, stronger, and more resistant to acids than hydroxyapatite. This means your teeth are not only remineralized, but stronger than they were originally!

• Why Adult Fluoride Treatments?

While fluoridated water and fluoride toothpaste might be all you need for strong enamel, there are several conditions that make fluoride treatments a good addition to your preventive care at our Hiawatha, IA office.

• Problems with dental hygiene. Consider fluoride treatment if you have trouble brushing and flossing, if you wear braces, or if there’s any other reason that makes daily cleaning more difficult.
• Exposed roots. Gums often recede as we age, and can pull away from the teeth even further with added factors like gum disease, harsh brushing habits, teeth grinding, or smoking. As gums recede, parts of the tooth roots are exposed. Because roots are covered with cementum instead of the much harder enamel, they are more vulnerable to decay.
• Dry mouth. Medical conditions, medications, and aging can cause a decrease in saliva production. Because saliva helps wash away food particles and bacteria, bathes the teeth with minerals that strengthen enamel, and neutralizes acids, less saliva can equal more cavities.
• Our individual biology. Some of us are born with weaker tooth enamel, and so are more at risk for cavities—even with great brushing and flossing habits.

In all of these cases, fluoride treatments can provide the extra protection you might need for stronger tooth enamel and improved dental health.

• Treatments Are an Easy Addition to Your Dental Appointment

Regular fluoride treatments are neither complicated nor time-consuming. Fluoride can be administered as a varnish, a gel, a rinse, or a foam. It can be applied with a brush, a swab, as a mouthwash, or in a tray. After application, Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying will let you know if any follow up instructions, such as avoiding food and drink for 30 minutes after treatment, are necessary. That’s all there is to it. Protection lasts for months, and your dentist can let you know when a re-application is needed.

You’re doing the right thing by using a fluoride toothpaste and keeping up with your dental exams and cleanings. Ask Dr. Sardzinski, Dr. Wilken, Dr. Stanley, Dr. Hanson and Dr. Heying if a fluoride treatment is something that could strengthen your teeth and help prevent decay—it could be a game-changer for your dental health!
