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, our doctor 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 our doctor 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 Ashland 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 our doctor 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.

You’re getting ready for a night out, or you’re checking to make sure you removed every bit of spinach after eating, or you’re practicing your best selfie smile . . . and suddenly, you see something alarming in the mirror—tiny cracks in your tooth enamel! Is this a dental emergency?

Almost always, the answer will be no.  Cracks like this are most likely “craze lines,” and craze lines are not serious cracks in your teeth. These diminutive flaws are shallow vertical cracks in the enamel which don’t go all the way through the tooth and don’t affect the tooth’s structural integrity. Like the crazing on a piece of glazed pottery, these tiny cracks are superficial, and the only reason for concern is cosmetic.

• Cause for Crazing?

Time and normal wear on our enamel are the most common culprits. Years of biting and chewing are stressful.

But you can help prevent additional craze lines by avoiding bad habits which can put external stress on your teeth: nail biting, knocking on teeth with oral jewelry, crunching down on ice cubes, using your teeth to open bottle caps—in fact, using teeth for anything other than chewing food.

Grinding your teeth is also hard on your enamel. If you suffer with bruxism (the medical term for tooth grinding), ask our doctor about a mouthguard or night guard. Eliminating the extra stress of unconscious grinding and clenching reduces the chances of craze lines. Even better, getting treated for bruxism can reduce the risk of serious pain and damage to your teeth and jaws.

• Staining Can Make Craze Lines More Visible

Craze lines are often invisible unless the light is just right. However, you can make craze lines more noticeable if you drink coffee, tea, red wine, or dark sodas regularly. And if you need another reason to give up tobacco products, smoking, chewing, or any other use of tobacco can also darken craze lines.

Stains in craze lines don’t usually respond to brushing. You might be able to lighten stains with home or professional whitening. Ask our doctor for the options which are best for your staining.

• Repairing Craze Lines

Don’t let tiny flaws keep you from smiling! If you are unhappy with the appearance of your enamel, talk to us about possible treatments, including bonding and porcelain veneers.

• When It’s More Than a Craze Line

While a craze line is generally nothing to be concerned about, a deep line, or a line which is getting bigger, might suggest a crack in the tooth. Cracks need to be assessed and treated to avoid damage not only to the exterior of the tooth, but to the pulp of the interior as well.

How can you tell the difference? Craze lines are not painful; a cracked tooth might be. Sensitivity to hot and cold foods, painful chewing, gums swollen around a tooth, pain when you bite down, a crack that is getting larger—any of these symptoms could be a sign that you have a cracked tooth. These are reasons to visit our Ashland dental office ASAP.

Craze lines might be medically harmless, but if they impact your confidence, that’s a problem. Our team can help you change habits that are causing craze lines, remove staining, or repair cosmetic damage. If you’re not crazy about those craze lines, ask us for solutions that will bring back your confidant smile.

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 our doctor at our Ashland office right away. Our goal is for you to keep your teeth healthy and strong, and for a lifetime!

our doctor and our team at Ashland Dental Care get this question a lot. Wisdom teeth are the last teeth to come in, once young people get their adult teeth. Because they are the last teeth to break through the gums, they are often called the third molars. There are four wisdom teeth: two on each side of the top and bottom of the mouth.

There is no hard-and-fast rule that says everyone must have the wisdom teeth removed. There are certain situations in which they either cause problems directly, or create a situation where there is a greater likelihood problems will arise eventually.

Impacted wisdom teeth

If our doctor and our team say you have a soft tissue impaction, it means your wisdom tooth is covered by gum tissue that is preventing it from erupting — most likely because your mouth is too small to provide the tooth with the room it needs to emerge.

The term “partial bony impaction” means that gum tissue is covering the wisdom tooth, but part of the jaw bone is also covering it, in which case there is no room in your mouth for the tooth to erupt. The opposite end of this spectrum is a complete bony impaction, where the wisdom tooth is completely covered by gum tissue and the jawbone, which prevent it from ever erupting.

The importance of removing impacted wisdom teeth

Dentists often want to remove impacted wisdom teeth because of the likelihood that they will cause problems, or because a problem already exists. One such problem is pericoronitis, an acute abscess that affects partially impacted wisdom teeth. Food, bacteria, and other mouth debris can become lodged under the gum flap that covers the wisdom tooth, which prevents it from erupting. Pericoronitis symptoms include pain, swelling, and the presence of an abscess.

Regular dental checkups will enable your dentist to keep an eye on your wisdom teeth, especially if they have some type of impaction. our doctor and our team at Ashland Dental Care typically recommend removal of impacted wisdom teeth because of the likelihood that severe infections such as pericoronitis will develop.
