It seems like sharks are everywhere these days—on land, sea, and air(waves). A halftime show meme gone viral. A week of summer TV devoted to our favorite apex predators. And who doesn’t have “Baby Shark” playing in their heads all day once they’ve heard it? But are we jumping the shark to discuss this topic in an orthodontic blog?

Not at all! Because today, we’re going to talk about shark teeth—just not the ones you might be expecting.

One of the expected sights when a shark opens its mouth are those rows and rows of shiny shark teeth. Sharks can grow from two to 15 rows of teeth at any one time (and some sharks have even more). This means sharp new teeth are always ready to replace any shark tooth which is lost, broken, or worn out.

An unexpected sight? When children point to their new adult tooth or teeth coming in—right behind their still-firmly rooted baby teeth! This double set of teeth is called “shark teeth,” and, while it certainly might come as a surprise, it’s not all that uncommon. But why do children develop shark teeth at all?

After all, baby, or primary, teeth have small roots, and are designed to come out easily when the adult teeth start arriving. When a permanent tooth starts to erupt, it pushes against the root of the baby tooth above it. This pressure gradually dissolves the root of the primary tooth, and with nothing to anchor it, it’s now loose, wiggly, and ready to fall out. That’s why baby teeth often look like they have no roots at all when they eventually wiggle free.

Sometimes, though, the roots of a primary tooth don’t break down, which means baby teeth stay right where they are. It also means that the permanent teeth have to erupt somewhere else—usually behind those stubborn little baby teeth.

Shark teeth can first appear around the ages of five to seven when the permanent front teeth start arriving, or several years later, when the adult molars begin to come in. Any extra teeth in one small jaw naturally raise concerns about tooth misalignment, especially when those extra teeth are molars. If double molars are causing crowding, it’s a good time for your child to have an orthodontic examination at our Aiea, Hawaii office to make sure the permanent teeth are properly positioned.

Unlike sharks, we don’t have an endless supply of replacement teeth, so it’s understandable to worry when you see anything unexpected. If you want to know more about shark teeth, or if you have any concerns, don’t hesitate to call Dr. Curtis N. Kamisugi for expert advice.

While everyone understands that a dentist takes care of teeth, not everyone is aware of what an orthodontist does. This confusion sometimes leads to misunderstandings about what Kamisugi Orthodontics does for our patients and how exactly Dr. Curtis N. Kamisugi can help them. Let’s take a closer look at a couple of the myths and misconceptions about orthodontists.

Perhaps the biggest misconception about the orthodontist is that they’re just like your family dentist. The truth is, they’re actually very different. While it’s true that both orthodontists and dentists care about helping you enjoy a lifetime of good dental and oral health, orthodontists go about achieving this goal in different ways. For instance, if you need to have a cavity filled, you probably won’t make an appointment to see an orthodontist. Dentists are the health professionals to see if you’re concerned about a cavity or need a filling. A dentist can also treat gum disease, tooth decay, toothaches, and other common oral health problems.

People see an orthodontist for very particular services. Most of the patients we see on a daily basis are here because they have braces, or they need to be fitted with braces or another form of tooth-straightening device. In other words, they consult an orthodontist when they are concerned about the alignment of their teeth. As a child grows up, his or her teeth may come in crooked. This can happen for a number of reasons, so it’s important for an orthodontist to take a look at a child’s teeth at about seven years of age. At that age, it’s possible to detect any problems that have not become too advanced to treat easily. Your family dentist may also refer your child to an orthodontist once the adult teeth have fully grown in.

Another common misconception about orthodontists is that they only treat children. It’s true that when you visit an orthodontic clinic you’re apt to see a lot of young kids, but you’ll also see teenagers, college students, and adults. Because crooked teeth can be caused by a number of different factors, it’s entirely possible for someone to require orthodontic treatment at any age.

If you want to know more about the practice of orthodontics or what your orthodontist can do for you, then simply ask Dr. Curtis N. Kamisugi. It’s best to get answers to your specific questions directly from the person who will be treating you. While you’re sure to find Internet resources helpful, there really is no substitute for the personal attention you’ll get during your appointment at our Aiea, Hawaii office.

Why all the fuss about fluoride? Your dentist recommends it, your toothpaste is formulated with it, most of our drinking water contains it. Just what is it about this mineral that makes dental professionals sing its praises? Read on for three good reasons why fluoride is a healthy choice for healthier teeth.

1. Fluoride Works!

Fluoride is an attractive option for protecting your teeth—and we mean that literally. Fluoride protects the surface of your teeth by working on a molecular level to attract minerals which strengthen enamel and help prevent cavities.

Our tooth enamel is mostly made from calcium and phosphate ions. These elements combine to form hydroxyapatite, strong crystals which make up about 95% of our enamel. Hydroxyapatite is so strong, in fact, that tooth enamel is the hardest part of our bodies. What can go wrong?

Acids. Acids created by the bacteria in plaque and the acids in our diet strip away the calcium and phosphate ions in enamel, weakening the surface of the tooth. This process is called demineralization. Over time, weak spots become bigger as acids eat through enamel to the inner tooth, causing decay and cavities.

So, what can fluoride do?

First, fluoride helps remineralize tooth enamel. Fluoride is attracted to the tooth’s surface and bonds with its minerals. It also attracts the calcium and phosphate ions that are found in our saliva to restore any minerals that have been lost. This process helps repair any weak spots that might have begun to form.

But fluoride does more than restore and repair tooth strength—it improves it! Fluoride ions join with calcium and phosphate to form fluorapatite crystals, which are larger and stronger than hydroxyapatite crystals. Even better? These new crystals are more resistant to acids.

2. Fluoride Is Doubly Effective

Fluoride works both externally and internally. We just looked at how fluoride helps keep teeth strong when applied to the outside of the teeth. This is called a topical application. Systemic benefits come the fluoride we consume in our diets.

Fluoride isn’t found in many foods, but it is found naturally in lakes, rivers, and other water sources. When the local water’s fluoride level is low, many communities add fluoride for its proven ability to prevent cavities. Water fluoridation is safe, has been studied for decades, and has been shown to reduce the risk of cavities by 25% or more for both children and adults.

Systemic fluoride was important when you were younger and still had your baby teeth. This is because fluoride joined with minerals in your adult teeth while they were growing and developing, creating stronger, more cavity-resistant teeth even before they erupted.

And now that your permanent teeth are here, you’re still in luck! When you drink fluoridated water, you’re increasing the amount of fluoride in your saliva. Just like fluoride toothpaste, saliva bathes your teeth with fluoride ions, remineralizing and strengthening the tooth surface and helping repair weak spots in your enamel.

3. It’s Easy to Get Fluoride Protection

Because so much of our drinking water is fluoridated, most of us really don’t have to think about how to get the recommended amount of fluoride in our diet each day. If your community’s water is low in fluoride, Dr. Curtis N. Kamisugi can help you. Prescription fluoride rinses, gels, supplements, and other treatments are available at our Aiea, Hawaii orthodontic office to make sure that your teeth are well-protected, wherever you may live. We will let you know which products are best for you and how often to use them.

Most toothpastes are formulated with fluoride, so you’re getting the enamel-strengthening benefits of this mineral every time you brush. Keeping up with your brushing is especially important while you’re in orthodontic treatment.

Because wearing traditional braces can mean it’s harder to reach all the plaque on your teeth, especially behind wires and around your brackets, that demineralization we talked about earlier is a common problem during treatment. Demineralization often leads to discolored white spots on enamel and, eventually, cavities. If you need more protection than toothpaste alone provides, Dr. Curtis N. Kamisugi will suggest fluoride treatments to reduce the risk of demineralization and even reverse some of its effects.

Fluoride isn’t, of course, the only way to look out for your dental health. Proper brushing and flossing are still essential for removing plaque. And sealants for both kids and adults provide long-lasting protection for chewing surfaces. But when it comes to a proven cavity-fighter that’s simple to use, effective, and easily available—is it any wonder we’re big fans of fluoride?

All Hallows’ Eve, more commonly known as Halloween, is a yearly event celebrated on October 31, and one that is anticipated by the young and young at heart all over the world. Some scholars claim that Halloween originated from Celtic festivals that honored the dead or that celebrated the harvest, while others doubt that there’s any connection at all to Samhain (a Gaelic harvest festival.) Regardless of its origin, our team at the orthodontics office of Dr. Curtis N. Kamisugi hopes that Halloween is fun and enjoyed by all of our awesome patients!

Trick or treat?

In North America, Halloween is predominantly celebrated by children who dress up in costumes, which range from scary to cute, who then go around the neighborhood knocking on doors asking “trick or treat”, and they are given candy in return. Trick-or-treating is a time honored tradition, and though many parents groan at the pounds and pounds of candy collected by youngsters and fear for the health of their teeth, there are a few things you can do to help their teeth stay in great shape until the candy is gone:

• Limit the amount of candy they can consume each day
• Have them brush their teeth after eating candy
• Avoid hard, chewy candies as they can stick in hard to brush places
• Keep candy out of sight to reduce temptation
• Don’t buy candy too far in advance to limit pre-Halloween consumption
• Help or encourage your children to floss

Halloween Fun

Halloween isn’t just about gorging on candy; there are other events associated with this festive day including carving jack-o’-lanterns, painting pumpkins, decorating sugar cookies, bobbing for apples, going to haunted houses, or just curling up on the couch with a bowl full of popcorn and watching some classic, scary movies.

Halloween Around the World

Some countries, like Australia, frown upon Halloween, claiming it is an American event and not based in Australian culture, while others like Italy have embraced the fun and celebrate much as Canadians and Americans do. Mexicans have been celebrating this fun day since around 1960, and it marks the beginning of the Day of the Dead festival. Some countries in Europe have come late to the party, but since the 1990s, countries like Sweden, Norway, and Germany have started celebrating Halloween as well, and finding children in costumes or having ghosts hanging in windows has become commonplace.

Halloween is about fun; stepping outside our normal lives and donning a costume or gathering with friends to knock on doors and ask for candy is as much a part of our culture as hot dogs and barbecue on Labor Day. Have a safe and happy Halloween from the team at Kamisugi Orthodontics!
