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. Kelly Peterson at our Marysville, WA office right away. Our goal is for you to keep your teeth healthy and strong, and for a lifetime!

A as in Ascorbic Acid

Ascorbic acid is just another name for vitamin C, which is one of the so-called “essential nutrients.” These are nutrients that are necessary for our bodies to function properly, and which must be supplied through our diets. Why is ascorbic acid essential?

First and foremost, because we have to have vitamin C for the formation of collagen.

We’ve probably all seen the ads promoting collagen as a fountain of youth for our skin. Whether or not a cream can turn back time is a matter for debate, but there’s no question as to the vital role collagen performs in our own bodies. That’s because collagen is the substance that provides both structure and support to our tissues, forming the basis of the connective tissue that holds us together. (The Greek root “kolla” means glue!) Organs, blood vessels, muscles, bones, skin, even the dentin in our teeth all rely on collagen to function.  

And if that weren’t enough for one vitamin, vitamin C also helps the body repair tissue, absorb iron, form teeth and bones, produce neuro-transmitters, and acts as an antioxidant. Whew! So, how often should we be eating foods rich in vitamin C? Maybe more often that you would think.

B as in Biology

The human body is an amazing thing! We can store many of the essential nutrients we need to keep ourselves healthy in our livers and fat tissue, even if fresh food sources aren’t immediately available. Unfortunately, Vitamin C is one of those vitamins that we can’t store in the body. This means that unless we get the vitamin C we need in our diet on a regular basis, we’ll experience vitamin C deficiency. How serious is that?

The importance of vitamin C to our health can’t be overstated. Vitamin C deficiency over a period of months actually causes a serious disease called scurvy. Without vitamin C, collagen formation breaks down. And when collagen breaks down, it leads to the breakdown of all those parts of the body that rely on collagen. In the short term, scurvy causes gum pain, fatigue, weakness, and body aches. Over longer periods, scurvy can lead to bruising, skin hemorrhages, anemia, tooth loss, severe gum disease, organ failure, and even death.

Luckily for us, scurvy is largely a disease of the past, thanks to the easy availability of fresh fruits and vegetables which provide us with vitamin C. So, which items should we add to the shopping list?

C as in Citrus—and So Much More!

When we think vitamin C, we instantly picture citrus fruits. Oranges, lemons, limes, grapefruit, and all their cousins are a wonderful source of vitamin C. Looking for a little more variety? You’re in luck! Fruit fans can load up on strawberries, kiwi fruit, mangos, and papayas. Love your veggies? Red peppers, kale, cauliflower, Brussels sprouts, and broccoli contain more vitamin C per serving than a medium orange. You can also take vitamin C supplements, but be sure to follow the recommended dosage. You can have too much of a good thing.

While we’re here, let’s add one last letter to the list:

• D as in Dental Health

So, why are we talking about vitamin C on a dental blog? Because vitamin C is essential to our dental health. Healthy gum tissue, strong connective tissues that hold our gums to our teeth and our teeth in our jaws, faster healing, antioxidants—all have been linked to a diet rich in vitamin C.

Careful brushing and flossing, regular checkups and cleanings at our Marysville, WA office, a balanced diet—these are all ways you can be proactive when it comes to your dental health. Talk to Dr. Kelly Peterson about the best vitamins and minerals for healthy teeth and gums. Vitamin C is a great beginning, but there’s still an alphabet from vitamin A to Zinc left to go!

Our teeth are a lot more complicated than they look. Beneath that shiny white surface is an entire system of different cell tissues working together to keep each tooth vital and healthy.

• Enamel, the protective exterior of the crown (the visible part of the tooth), is the strongest substance in the body and the first line of defense against damage to our teeth.
• Dentin, the hard tissue under the enamel and cementum, has microscopic tubules that connect to the pulp.
• Pulp, the tissue at the center of the tooth, contains the nerves, blood vessels, and connective tissue that keep the tooth alive.
• Cementum, composed of connective tissue which forms the protective exterior of the root, also attaches to fibers in the periodontal ligaments which hold the teeth securely in the jaw.

Because cementum is below the gum line, it’s generally safe from the cavity-causing conditions that our enamel is exposed to every day. But there are still potential hazards that we should be aware of.

• Cementum Erosion

With a name like “cementum,” it’s logical to assume that this is the hardest tissue in the body. Actually, however, that distinction goes to our enamel. And if even our enamel can be damaged by bacteria and plaque, cementum doesn’t stand a chance!

How does cementum come in contact with cavity-causing bacteria? Gums often recede as a natural part of the aging process, leaving part of the root exposed. Gum disease, failure to brush and floss regularly, and heavy-handed brushing can lead to early gum recession. The newly exposed cementum is now exposed to the same conditions, which cause cavities in our enamel. But a root cavity can be trickier to treat and, because the cementum is not as strong as enamel, can progress more quickly. And if a cavity reaches the pulp, a root canal could be necessary.

But the erosion of cementum doesn’t have to result in a cavity to cause discomfort. When cementum is removed, the dentin beneath is exposed. Dentin, you’ll recall, contains tiny tubes that connect to the pulp of the tooth. The result? Conditions such as heat, cold, even an intake of air can cause tooth sensitivity as they stimulate the nerves in the pulp. If your hot coffee or ice cream cone is suddenly causing you pain, let us know. There are treatments, which can reduce tooth sensitivity.

• Gum Disease (Periodontitis)

In more severe cases of gum disease, the gums pull away from the teeth leaving pockets, which harbor plaque and bacteria. Left untreated, these pockets can become home to infections, which attack and destroy bone structure and connective tissue. Caught early, a treatment called tooth scaling and planing can help. In this type of deep cleaning, your dentist or endodontist will remove plaque and tartar and then smooth the root surface to make it harder for bacteria and plaque to stick. If the gums have receded too far, a gum graft might be necessary to protect the exposed roots.

• Trauma

The same traumas that can damage teeth above the gum line can result in injuries below it. Chewing on hard objects (ice, hard candies, wooden pencils), bruxism (tooth grinding), and sports injuries or accidents can cause cracks in the cementum. If your root is split or fractured, it might be possible to save your tooth, but sometimes extraction is the best option.

So how do you protect your cementum, hidden as it is under your gum line? The same way you protect the more visible parts of your teeth!

• Keep to a healthy daily routine of brushing and flossing. This will help prevent gum disease and keep gum recession at bay. Using a soft brush and brushing firmly but gently will remove plaque while protecting both enamel and cementum. If you notice tooth sensitivity, give us a call!
• Come in to our Marysville, WA office for regular dental exams. The best treatment for gum disease is prevention. When you come in for regular checkups, we are able to discover early signs of gum disease before it becomes a serious problem. If you are suffering from more advanced periodontitis, there are treatments available.
• Safety first when it comes to your smile. If you chew on hard objects, talk to Dr. Kelly Peterson about how to break the habit. If you grind your teeth, see us for solutions. If you play sports, let us know—often a mouthguard can help protect your teeth from injuries that could otherwise lead to more complex procedures or even tooth loss.

Maintaining your healthy dental habits is a lot like cementum—the foundation of a beautiful smile. Nothing complicated about that!

It might seem like you’ve gotten a great night’s sleep—but why aren’t you well rested? Worse, why are you waking up with:

• A headache
• Ringing in your ears or an earache
• Pain in your jaw
• Worn or sensitive teeth
• Dry mouth or mouth and cheek injuries
• An unhappy partner who’s been kept awake all night?

If you suffer from any or all of these symptoms, you might be one of the millions of people who have a sleep-related disorder called bruxism, better known as teeth grinding.

There are any number of causes that have been linked to bruxism. Stress and other negative emotions seem to trigger episodes, as can lifestyle habits such as smoking and drinking alcohol or caffeine. Sleep apnea can lead to grinding your teeth, or you could have bite or tooth alignment problems. Certain medications might set off this disorder, and some studies have shown a hereditary tendency in families. Whatever the reason you grind your teeth, there are many important reasons to stop as soon as you can.

As bad as the nagging headaches and earaches that can accompany bruxism can be, long-term damage to your teeth can develop over time. With continuing grinding pressure on the teeth, enamel is worn away prematurely. Teeth can crack or chip. They may loosen or develop sensitivity to heat, cold, and pressure. Gum tissue can recede or become inflamed. Dental restorations can be cracked or broken.

If you—or someone in your house—suspects that you are grinding your teeth at night, give our Marysville, WA office a call! We can recommend relaxation techniques, diet changes, or tips to help you relax your jaw. Dr. Kelly Peterson might suggest a nightguard, a custom-fitted appliance worn while you sleep, to reduce the impact of grinding. There are options available. Let’s work together to make every night’s sleep a restful, healthy one.
