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. Joel Hartjes and Dr. Jon Szewczyk at our Middleton, WI office right away. Our goal is for you to keep your teeth healthy and strong, and for a lifetime!

Did you know your toothbrush could be covered with almost ten million germs? We know … it’s gross! That’s why you should know how to store your toothbrush properly, and when it’s time to replace it.

If you need to brush up on your toothbrush care knowledge, we’ve got you covered so brushing will always leave you feeling squeaky clean.

Keeping a Clean Toothbrush

Your mouth is home to hundreds of types of microorganisms, so it’s normal for some of them to hang onto your toothbrush after you’ve used it. Rinsing your brush thoroughly with water after each use can get rid of leftover toothpaste and food particles that cling to the bristles. Some dentists suggest soaking your toothbrush in mouthwash every now and then can help reduce the amount of bacteria further.

Store your toothbrush in a cool, open environment away from the toilet or trash bin to avoid airborne germs. Closed containers should be avoided because they provide a warm, wet habitat that bacteria love to grow in.

If you have multiple people sharing one sink, an upright holder with different sections will keep everyone’s brushes separated and avoid cross contamination. In addition, we would hope this is a no-brainer, but please don’t share toothbrushes!

Microwaves and dishwashers are not suitable tools for cleaning a toothbrush, because brushes aren’t built to last through this kind of treatment. If you want a really clean toothbrush, your best option is simply to buy a new one.

Replacing Your Toothbrush

The American Dental Association recommends you replace your toothbrush every three to four months, or sooner depending on individual circumstances. Dr. Joel Hartjes and Dr. Jon Szewczyk and our team agree. If you have braces, tend to brush too strongly, or the bristles become frayed, it’s time for a new brush.

Children will also need replacement brushes more frequently than adults. If you or your child has been sick, you should replace the toothbrush immediately to avoid re-exposing yourself to illness.

Worn-out brushes are not only unsanitary, they don’t do a good job cleaning teeth. Bristles that are worn out and dull won’t scrape away plaque and bacteria as well as a fresh toothbrush can.

Though the idea of ten million germs can be worrisome, if you take a few small precautions, you may ensure your toothbrush stays in good shape. And the cleaner the toothbrush, the cleaner the smile!

HPV, or human papillomavirus, is the most common sexually transmitted infection in the country. There are over 100 strains of HPV, and, while most of these infections leave our systems on their own with no long-term ill effects, some cancers have been linked to certain “high risk” strains of the virus. One of these strains, HPV16, increases the risk of oral cancer.

HPV-related oral cancer most often appears in the oropharynx. This area of the mouth includes:

• The base, or back, of the tongue
• The soft palate
• The tonsils
• The back and sides of the throat

While HPV-related oral cancers can appear in other parts of the oral cavity, they most typically occur at the back of the throat and tongue and near the folds of the tonsils. Because of this location, oropharyngeal cancer can be difficult to detect. This is one more important reason to maintain a regular schedule of dental exams. Our examination doesn’t focus only on your teeth and gums. We are trained to look for cancerous and pre-cancerous conditions in the mouth, head, and neck to make sure you have the earliest treatment options should they be needed.

If you discover any potential symptoms of oropharyngeal cancer, call us for a check-up. These symptoms can include:

• Trouble moving the tongue
• Trouble swallowing, speaking, or chewing
• Trouble opening the mouth completely
• A red or white patch on the tongue or the lining of the mouth
• A lump in the throat, neck, or tongue
• A persistent sore throat
• Ear pain
• Unexplained weight loss
• Coughing up blood

Not every symptom is caused by cancer, but it is always best to be proactive. HPV-related oral cancer is rare, but it is on the increase. While HPV-positive oral cancers generally have a better prognosis than HPV-negative oral cancers, early diagnosis and treatment are still essential for the best possible outcome.

Finally, if you are a young adult or have an adolescent child, talk to Dr. Joel Hartjes and Dr. Jon Szewczyk and to your doctor about the HPV vaccine, which is effective before exposure to the virus occurs. Most HPV vaccines, while not designed specifically to prevent oral cancer, prevent the HPV16 strain from infecting the body—the very same strain that causes the majority of HPV-related oral cancers.  Although no studies have shown definitive proof yet, there is strong feeling in the scientific community that these immunizations might protect against HPV-positive oral cancer as well as cervical, vaginal, and other cancers. It’s a discussion worth having at your next visit to our Middleton, WI office.

You found the perfect toothbrush! The bristles are soft, to avoid irritating your delicate gum tissue. The angle of the bristles is perfect for removing plaque. The handle is durable and comfortable when you spend at least two minutes brushing in the morning and two at night. Why, you love this toothbrush and you’ll never let it go… for the next three or four months.

The life of a toothbrush is naturally a short one. Dr. Joel Hartjes and Dr. Jon Szewczyk and our team recommend replacement every three to four months because the bristles become frayed and worn with daily use. They cannot clean as effectively when the bristles begin to break down, and, depending on your brushing style, may wear out even more rapidly. (Children will probably need to replace toothbrushes at least every three months.) But even in the short time you have your toothbrush, there are ways to keep it ready for healthy brushing.

• Don’t share. While sharing is normally a virtue, sharing toothbrushes can lead to an increased risk of infections, especially for those with compromised immune systems or existing infectious diseases. Similarly, keep different brushes separate when drying to avoid cross-contamination.
• Rinse thoroughly after brushing. Make sure to remove any toothpaste or debris left after you brush.
• Store the brush upright. Air-drying is the preferred way to dry your brush, as covering the brush or keeping it in a closed container can promote the growth of bacteria more easily.

There are several products on the market that promise to sanitize your brush. The verdict is still out on its success, but if you or someone in your home has a compromised immune system, call our Middleton, WI office to see if it might be worth your while to check them out.

Even though your toothbrush won’t be with you long, make its stay as effective and hygienic as possible. And if you find a brush you love—stock up!
