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 Mount Vernon, WA 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. Andrew Nalin for expert advice.

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 that 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 that develops on one of those side surfaces of your teeth.

• Preventing Interproximal Cavities

Fortunately, prevention is about as basic as it can be—brushing and flossing effectively. Dentists 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 gum line—places where bristles just can’t reach.

When you wear braces, though, flossing isn’t quite so basic. Getting that floss just where it needs to be in between brackets and wires and in between teeth can be a challenge!

The good news is there are many products designed just to make flossing easier while you’re in orthodontic treatment:

• Floss threaders are flexible hoops that help you thread floss behind your wires easily.
• Precut floss strands use a stiff tip at one end for threading floss through wires.
• Interproximal brushes are tiny, cone-shaped brushes which can fit between your teeth and braces for precise cleaning.
• Water flossers eliminate floss altogether, using a pulsing stream of water to clean between and around teeth and braces.

During your next visit to our Mount Vernon, WA office, Dr. Andrew Nalin can give you tips on how to use any of these tools effectively for cleaner teeth and cleaner braces.

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 we 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 your dental team to make sure “interproximal cavity” doesn’t become a working part of your dental vocabulary.

Our team at Nalin Orthodontics knows that there are many ways you can protect your pearly whites throughout your orthodontic treatment. If you follow the rules and brush your teeth twice a day, floss often, and protect your appliances from damage, you should have a successful treatment.

But did you know there’s another way to keep your teeth sparkling and healthy during your time wearing braces?

Fluoride, the mineral that helps you prevent cavities and tooth decay, can also help keep your teeth strong. Fluoride comes in two varieties: topical and systemic. Depending on your oral health or the recommendation of Dr. Andrew Nalin, you may be required to have a fluoride treatment every three, six, or 12 months. We may also prescribe a fluoride product such as a mouthwash, gel, or antibacterial rinse for at-home treatment to keep your teeth happy in between visits.

If you have any other questions about fluoride or your treatment, please don’t hesitate to give us a call!

Orthodontists and dentists both help patients improve their oral health, but in different ways. Dentistry is a broad medical specialty that deals with the teeth, gum, nerves, and jaw, while orthodontics is a specialty within dentistry that focuses on correcting bites, occlusion, and the straightness of teeth. One important difference is that all orthodontists like Dr. Andrew Nalin are dentists, but not all dentists are licensed orthodontists.

How are they similar?

The main similarity between a dentist and orthodontist is that they both focus on oral care. An orthodontist can work in a dental office and provide the same care as a dentist. So in this respect, they are quite similar. They are both considered doctors, and deal with the teeth and gums.

How are they different?

There are more differences than similarities. An orthodontist requires additional schooling as a dental specialty; the situation is similar to a doctor who obtains additional schooling to become a surgeon. Another difference is that orthodontists specialize in helping patients with the alignment of their teeth, improving their bite, or fitting them for corrective braces and devices. If a patient has an overbite, a dentist will refer him or her to an orthodontist.

Dentists typically encourage good oral hygiene and provide services related to:

• Tooth decay
• Root canals
• Gum disease
• Crowns
• Bridges
• Veneers
• Teeth whitening

Orthodontists are dentists that specialize in the alignment of teeth, and provide services related to:

• Misaligned teeth
• Crowded teeth
• Overbite
• Underbite

What an orthodontist can help with

Orthodontists help with crooked teeth, but they assist patients with other issues as well. These include overbites and underbites, crossbites, spaces between teeth, overcrowding of teeth, and the treatment of temporomandibular disorders (TMD). Additional problems with the jaw also need to be treated by an orthodontist.

While a dentist may be trained to provide orthodontic care in addition to extractions, TMJ treatments, and fillings, trusting your smile to an orthodontist can better balance the different procedures you require.
