Time to brush! So, you make sure you gently brush the plaque off the outside surfaces of your teeth. You want to present a gleaming smile to the world, after all. And you make sure to brush the inside surfaces as well, because who wants to feel a fuzzy patch of plaque every time their tongue hits their teeth? And, naturally, you remember to clean the tops of your molars, because those crevices make them more cavity-prone than any other surface.

Done? Not quite!

You might be surprised to learn that no matter how well you’ve brushed all the visible surfaces of your teeth, you’ve left quite a bit of enamel untouched—the adjoining, or touching, surfaces of the teeth which sit next to each other.

You’ve probably noticed that your bristles can’t . . . quite . . . reach all the enamel between your teeth (especially between your molars!) when you’re brushing. This means that food particles and plaque have an easier time sticking around. And when the bacteria in plaque are left undisturbed, especially with a banquet of food particles available, they produce acids which gradually eat away at the enamel covering our teeth, creating a cavity.

Here’s where we work in some specific dental vocabulary. “Interproximal” means between the adjoining, or touching, surfaces of the teeth. And an interproximal cavity is a cavity which develops on one of those side surfaces of your teeth.

• Discovering Interproximal Cavities

Clearly, a cavity between the teeth won’t be as obvious as other cavities. How will you know if a dental appointment is in order?

There are typical symptoms which can show up when you have a cavity. Chewing might be painful. You might feel pain or sensitivity when you eat or drink something which is hot, or cold, or sweet. But pain and/or sensitivity aren’t always present, especially when a cavity is just beginning to develop.

Regular exams are important so you can catch small cavities before they become more serious. That’s why, at your regular dental exams, Dr. Kelly Peterson will always check for any signs of decay on every surface of each tooth, including those places which aren’t easily visible. And that’s why X-rays can be an important tool for locating these tricky cavities.

• Treating Interproximal Cavities

If Dr. Kelly Peterson and our team finds a cavity between your teeth, there are different treatment options available depending on the size of the cavity:

• A typical cavity will require a filling. The decay will be removed, and then the area will be cleaned and filled. You’ll probably choose a filling material which can be matched to your enamel color if the restoration will be noticeable.
• If decay has spread to the pulp chamber inside the tooth, a root canal is often the best treatment option, with a crown applied afterward to protect the tooth.
• A tooth so decayed or infected that it cannot be saved might require extraction.

Dealing with any weakness in a tooth as quickly as possible is always better than waiting until a more complicated treatment option is needed. Of course, the best treatment is prevention, and, luckily for us, it’s not a complicated process at all.

• Preventing Interproximal Cavities

In fact, it’s about as basic as it can be—brush and floss effectively. We recommend brushing for two minutes at least twice a day and flossing once each day. While most of us are good about keeping up with brushing, sometimes that daily flossing is more a goal than a reality.

But it’s flossing which really does the trick when it comes to interproximal cleaning. If you floss correctly, food particles and plaque are removed from between the teeth and around the gumline—places where bristles just can’t reach. The next time you get your teeth cleaned at our Marysville, WA office, ask for tips on how to perfect your technique. And, if you have difficulty flossing, ask about alternatives such as water flossers and interproximal brushes.

Preventing cavities on the exterior surfaces of your teeth is probably pretty much automatic by now, but don’t forget the potential for stealth decay! If Dr. Kelly Peterson and our team find signs of erosion on the sides of your teeth, or if your hygienist lets you know that you’ve got a lot of interproximal plaque buildup, work with us to make sure “interproximal cavity” doesn’t become a working part of your dental vocabulary.

Toothpastes come in many forms and boast different flavors, benefits, and endorsements. All are designed to remove surface bacteria and prevent the buildup of plaque that can cause tooth decay. With so many choices, Dr. Kelly Peterson and our team at Northwest Smile Design know that selecting the right toothpaste can be intimidating. After all, some benefits are welcome bonuses, while others are absolutely essential. So how can you know which toothpaste is best for you?

ADA Seal of Approval

While all toothpastes must first be approved by the Food and Drug Administration for sale to consumers, the American Dental Association puts these products through further rigorous tests for safety and effectiveness. Toothpaste that boasts the ADA Seal of Approval can be trusted to do exactly what it claims.

Fluoridated

Fluoride is an essential ingredient in a daily toothpaste. It helps to protect the tooth from decay by removing plaque and strengthening the enamel. Although fluoride is found in many public water supplies, many people are deficient in it due to the consumption of bottled water instead of tap water. All toothpastes with the ADA Seal of Approval contain fluoride.

Other benefits

If a toothpaste meets the ADA’s standards and contains fluoride, the next step is to clear it with your dentist. This is especially true if you decide to use a whitening toothpaste, which often contains abrasives to remove surface stains. Though abrasives are an effective aid in tooth whitening, they may not be recommended if you have weak tooth enamel.

Specialty toothpastes

In certain situations, Dr. Kelly Peterson may suggest or prescribe specialty toothpaste, depending on your oral health needs. For example, patients who are prone to tooth decay and cavities despite frequent brushing and flossing may benefit from prescription-strength fluoridated toothpaste to help prevent the weakening of tooth enamel. Others who suffer from tooth sensitivity may benefit from the use of desensitizing toothpaste. Talk with Dr. Kelly Peterson if you think a specialty toothpaste could be right for you by scheduling an appointment at our Marysville, WA office.

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!
