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 Bedford, NS 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 Drs. Magda Barnard & Lee Erickson for expert advice.

Some foods are just terrible for your teeth — think cookies and candy bars — but there are certain foods that are beneficial to your oral health. Below, Drs. Magda Barnard & Lee Erickson and our team have covered five of the top foods to keep your teeth and gums healthy!

1. Crispy, low-acid fruits and vegetables: Fruits like apples and vegetables such as carrots and celery act like “natural toothbrushes,” helping to clear plaque from your teeth and freshen your breath.

2. Kiwis: These little green superstars are packed with vitamin C which is essential for gum health. The collagen in your gums is strengthened when you consume foods that are high in vitamin C, like kiwis, thus helping to prevent periodontal problems.

3. Raw onions: Onions have long been studied for their antimicrobial, antibacterial, and antioxidant properties. Proliferation of bacteria is what leads to tooth decay and cavities. By including raw onions in your diet, you'll be doing your part to wipe out those little microbes before they can multiply!

4. Shiitake Mushrooms: A specific compound in shiitake mushrooms, lentinan, has been shown to have antibacterial properties that target the microbes that cause cavities while leaving other beneficial bacteria alone. It may also help prevent gingivitis, or inflammation of the gums.

5. Green Tea: Often lauded for its high antioxidant content and many health benefits, it turns out green tea also benefits your oral health! A Japanese study found men who drank green tea on a regular basis had a lower occurrence of periodontal disease compared to men who drank green tea infrequently. It's believed this is due to the catechins in green tea, a type of flavonoid that may help protect you from free radical damage, but more research needs to be done. Either way, drink up for your overall health, as well as your teeth!

When we think orthodontics, we commonly think teeth. Naturally! Straight teeth and a beaming smile are everyone’s orthodontic goal. But orthodontics is a field which specializes in more than misaligned teeth. While your beautifully aligned teeth are the visible outcome of your orthodontic work, a properly aligned bite is the foundation for your healthy smile.

A malocclusion occurs when the teeth and jaws aren’t properly aligned—they don’t fit together the way they should when the mouth is closed. A malocclusion, or bad bite, affects many people to some degree, but not always in exactly the same way. Some of the different types of malocclusion include:

• Crossbite

A crossbite occurs when upper teeth fit inside lower teeth. An anterior crossbite refers to the front teeth, with one or more upper front teeth, or incisors, fitting behind lower front teeth. A posterior crossbite affects the back teeth, with upper teeth fitting inside the lower teeth on one or both sides of the jaw.

• Crowding

When the jaw is small and/or the teeth are large, lack of space can result in crowded, twisted, or crooked teeth.

• Open bite

An anterior open bite means that the front teeth don’t close when biting down, leaving an open space between the upper and lower teeth. A posterior open bite occurs when the back teeth don’t make contact when the front teeth close.

• Overbite

Our upper front teeth naturally overlap the lower ones a small bit when the teeth are closed. An overbite occurs when the upper teeth significantly overlap the lower teeth.

• Overjet

When the upper front teeth protrude too far forward over the bottom teeth, it’s called an overjet, or, sometimes, buck teeth. Where an overbite causes a vertical overlap, an overjet takes into account the horizontal relationship of the teeth.

• Spacing

A jaw that is large, teeth that are small, missing teeth—these conditions can lead to gaps between the teeth.

• Underbite

An underbite results when the lower teeth and jaw extend further forward than the upper teeth and jaw, causing the bottom teeth to overlap the top teeth.

If you have a malocclusion, what comes next? This depends.

Some malocclusions are so minor that no treatment is necessary. Some are the result of misaligned teeth. Some occur because the upper and lower jaws are growing at different rates. Some are a combination of teeth and jaw misalignments. Some are caused by genetics, while others are caused by injuries or habits like prolonged thumb sucking or tongue thrusting.

Because malocclusions are so varied, your treatment plan will be designed for your specific needs. Braces, aligners, appliances like the Herbst® appliance or the palatal expander, surgery for severe malocclusions—there is a larger variety of treatment options than ever before to help you achieve a healthy bite.

When teeth and jaws don’t fit together as they should, the consequences can be damaged teeth and enamel, problems with the temporomandibular joint, headaches and facial pain, and difficulty chewing, eating, and speaking.

The good news is that early intervention for children can help correct teeth and jaw problems before they become more serious, leading to easier orthodontic care in the teen years, and helping to avoid the possibility of surgery or extractions. This is why Drs. Magda Barnard & Lee Erickson and our team recommend an orthodontic assessment at our Bedford, NS office for children around the age of seven.

If you’re an adult with concerns about your teeth or bite, there’s good news for you, too. Drs. Magda Barnard & Lee Erickson can devise a treatment plan to improve your bite and your smile no matter what your age.

Of course, despite our title, there’s really no such thing as a “common malocclusion” when we’re talking about your dental health. Each person—and each smile—is unique. Drs. Magda Barnard & Lee Erickson will diagnose your malocclusion and create a personalized plan carefully tailored to your exact needs, for an uncommonly attractive, confident, and healthy smile.

One of the many benefits of your clear aligners is that you can remove them to eat. You should brush after every meal, just like you would with traditional braces, but cleaning your teeth is much easier without having to work around and between brackets and wires.

But when you wear your aligners 22 hours a day, you might be tempted to leave them in when you’re just having a sip of something when you’re thirsty. Unless you’re drinking water, please don’t.

What’s the problem with a can of cola or a cup of coffee?

• Staining

The virtue of your clear aligners is that they are, well, clear! Probably one of the reasons you decided on this method of treatment was because you liked the idea of an inconspicuous appliance.  Unfortunately, dark beverages such as colas, coffee, tea, and red wine can stain your aligner, making it more visible.

• Warping

Very hot beverages might actually affect the shape of your aligners. Since they are formed using heat, it makes sense that heat can also de-form them. If hot teas and coffee drinks cause a change in the shape of your aligners, they will not move your teeth the way they were meant to.

• Affecting Tooth Health

Even though our enamel is very strong, sugary and acidic drinks can damage it. Acidic foods can erode enamel, and the sugars in our diet provide food for cavity-causing bacteria, which then produce acids that erode enamel.

Normally, saliva provides some protection from acids and sugars by diluting them and washing them away from the teeth. When you drink a cola or an orange juice with your aligners on, some of the liquid will get in them, and can stay in them until the aligners are removed. You will actually give these problem beverages the opportunity to bathe your teeth in sugar and acid over a longer period of time, without exposure to saliva to help offset potential harm. And after all your work to create a beautiful smile, you certainly don’t want new cavities!

How to protect your aligners and keep them their cleanest—and most invisible?

• Take your aligners out before drinking beverages that can stain them, or, if you can’t, try using a straw. Clean your aligners according to Drs. Magda Barnard & Lee Erickson and our team’s instructions to keep them as clear as possible.
• Don’t drink very hot beverages with your aligners in place. Try icing your coffee and tea if you can’t remove your aligners. And if you think your aligners have changed shape, please give us a call.
• Drink water! Water hydrates you, doesn’t damage enamel, and keeps your aligners clean. Tap water is your best option, as even bottled waters can be acidic.

If your aligners should become stained, remember that you change them frequently, so the staining can be a temporary problem. If you do have a drink of something hot and your aligners feel “off,” give our Bedford, NS office a call. We’ll let you know if you need to replace them.

But prevention is always best! Avoid staining from the start by removing your aligners before you drink dark beverages. Don’t expose your aligners to heat. Think about replacing unhealthy drinks with water. And certainly brush right away, or rinse with water if that’s not possible, if you drink a sugary or acidic beverage. These simple precautions will help keep your aligners, and, most important, your teeth, looking their best.
