An overbite is one of the most common malocclusions. If Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard and our team have diagnosed you with an overbite, you probably have lots of questions. Let’s try to answer some of them!

Just what is an “overbite”?

A malocclusion is another way of saying that you have a problem with your bite, which is the way your jaws and teeth fit together when you bite down. In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. A normal overlap is generally considered one or two millimeters.

An overbite is a Class II malocclusion, and means that the upper front teeth cover more of the lower teeth than they should. But that’s a very general definition, and we will diagnose and treat your own, very specific, bite and teeth alignment.

Because overbites aren’t all alike. They might be barely noticeable. Upper teeth might overlap lowers by an extra millimeter or two. In more severe overbites, the upper teeth might cover the lower teeth completely. The amount of overlap and the cause of the overbite will determine your treatment.

What causes an overbite?

Overbites can be dental, caused by tooth alignment, or skeletal, caused by bone development, or a combination of both. They are usually hereditary, so, most often, an overbite is something you’re born with.

The size and position of your jaws, the shape and position of your teeth, all affect your bite alignment. But early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use can contribute to overbite development. Missing teeth and bruxism, or tooth grinding, can also affect the alignment of your bite.

How do we treat an overbite?

There are many types of treatment available. Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will recommend a treatment plan based on the type and severity of your overbite. Because some treatments are effective while bones are still growing, your age plays a part as well.

• Braces and Aligners

If dental issues are the main reason for your overbite, braces or clear aligners can be very effective. Rubber bands are commonly used to help bring teeth and jaw into alignment.

• Functional Appliances

If the overbite is caused by a problem with upper and lower jaw development, devices called functional appliances can be used to help guide the growth of the jawbones while a child’s bones are still forming.

For young patients, there are several appliances that can help correct an overbite. Some, like the Herbst appliance, work inside the mouth, while others, like headgear, are worn externally. Your orthodontist will recommend the most effective appliance for your needs.

• Surgical treatment

In some cases, where the problem is skeletal rather than dental, surgical treatment might be necessary to reshape the jawbone itself. This is especially true for adults, whose bones have finished forming.

If we recommend surgery, oral and maxillofacial surgeons are experts in surgical procedures designed to create a healthy and symmetrical jaw alignment. Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard will work with your surgeon to design a treatment plan, which will usually include braces or other appliances following surgery.

Why treat your overbite?

Sometimes, a very slight overbite won’t require treatment. A serious, moderate, or even mild overbite, though, can lead to many dental and medical problems, including:

• Crooked, crowded teeth
• Worn teeth and enamel
• Problems speaking or chewing
• Difficulty sleeping
• Headaches, facial, and temporomandibular (jaw) joint pain

When you work with our Halifax team to correct your overbite, you’ll not only prevent these unpleasant consequences, but you’ll achieve major benefits as well—a healthy, comfortable bite, and an attractive, confident smile. If you’d like more than an overbite overview, Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard can provide the specific information and treatment plan you need to make that healthy bite and that confident smile a reality!  

Between the huge number of toothpaste brands on the market today, the different flavors, and claims from most to do different things, it isn’t surprising that people feel so confused when it comes to something that should be as simple as buying a tube of toothpaste. This guide will help you identify the common ingredients in toothpaste, and help you understand the important factors to consider before buying toothpaste again.

Toothpaste comes in gel, paste, and powdered forms. When it comes to the type of toothpaste, the choice is more a matter of preference.

Basic Ingredients

• Abrasive Agents – Abrasive agents are the scratchy substances added to toothpastes to help in the removal of food particles, bacteria, and minor stains. Calcium carbonate is one of many abrasive materials, and arguably the most common.
• Flavor – When toothpastes are flavored, they almost always have artificial sweeteners to enhance the flavor of the toothpaste and increase the likelihood that you’ll use it. Flavors run the gamut from traditional mint to cinnamon that may appeal to adults, and bubble gum or lemon lime – flavors to target children.
• Humectants – Humectants are moisturizing agents that keep paste and gel toothpastes from drying out. Glycerol is commonly used as a humectant.
• Thickeners – Thickeners are used to give toothpaste its distinctive consistency, and to make it maintain a uniform consistency and come out of the tube easily.
• Detergents – Sodium lauryl sulfate is the most common detergent used in products that foam up, like toothpaste does in your mouth.

What to Look For in Toothpaste

Fluoride is naturally occurring mineral. It is the most important ingredient to look for in a toothpaste. Although there are people who argue against using fluoride toothpaste, dental professionals like Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard emphasize that the fact that the incidence of tooth decay has decreased so significantly in the past 50 years is because of fluoridated toothpaste.

The suggestion that fluoridated water gives you enough fluoride to protect your teeth is wrong. Fluoride toothpaste is the best cavity protection there is. In addition to strengthening tooth enamel and protecting teeth from acid erosion (from acidic foods and drinks,) it remineralizes the surfaces of teeth that are suffering from early acid damage and may prevent developing tooth decay from worsening.

Tartar Control

Tartar is the result of hardened plaque buildup on the teeth. Good oral hygiene and in between twice yearly cleanings from a dental hygienist are the best defense against plaque buildup. Plaque turns to tartar when people neglect their oral hygiene. Over time, tartar can build up on teeth and under the gums, increasing the risk of gum disease.

Your best bet is to use a toothpaste that has a combination of anti-plaque agents. Products containing more than one plaque reducer may be more effective than products that only one. Common ingredients to look for are zinc citrate or pyrophosphates. Triclosan is an antibiotic that is believed to kill bacteria in the mouth, and it can be found in some anti-plaque toothpaste.

Look for toothpaste that bears the seal of the Canadian Dental Association. That seal is an endorsement of the CDA – and it means that many dentists agree that that particular toothpaste does what toothpaste is designed to do. We can also recommend toothpaste to meet your specific oral health concerns at your next visit to our Halifax office.

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 Halifax 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. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard for expert advice.

If you’re heading back to classes in the next few weeks, you’re probably getting your gear together now. So let’s talk about some of the items you can pack to make orthodontic care easier during school hours.

• Dental-Healthy Food

Watching what foods you eat is especially important now. If you’re carrying your lunch or snacks in your pack, you want to be sure that they’re approved for braces and aligners.

If you wear braces, avoid foods which are sticky, chewy, or crunchy. They can stick to your teeth (making it easier for cavities to develop) or cause damage to your brackets and wires (making repairs necessary). Your orthodontist will give you a list of braces-friendly foods.

If you have clear aligners, even though you’ll remove them to eat, that sticky rule still applies. You don’t want food trapped in your aligners if you can’t brush right after eating, because that food is also food for the oral bacteria which cause cavities.

Bringing a water bottle with you is a great idea if it’s hard to brush after eating. Rinsing with water is a good way to get rid of loose food particles, and staying hydrated helps maintain normal saliva production—which also helps wash away food debris.

• Toothbrush, Toothpaste, and Floss

It’s best to clean your teeth after every snack and meal if at all possible. A travel-sized brush, toothpaste, and dental floss or picks designed for braces will help you get rid of any unwanted dental leftovers. And a small mirror can help you discover any lingering food particles.

It’s especially important now to practice careful hygiene, so be sure to wash your hands before and after cleaning your teeth or appliances.

• Your Aligner or Retainer Case

Whenever you take off your retainer or aligners to eat, you should always have your case handy. Cases make sure your appliances stay off germy desk and table surfaces—or worse, floors—and protect them from breakage. A case is also a good way to make sure your retainer doesn’t accidentally end up in a trash bin after lunch.

Again, before and after you handle your braces, aligners, or retainer, be sure to wash your hands carefully.

• Dental Wax & Extra Bands

Sometimes a wire comes loose or a bracket irritates the inside of your cheeks or mouth. In this case, dental wax is a great way to protect yourself from irritation and injury. And if a band is lost or breaks, it’s always good to have a spare (or two) handy. As always, handwashing rules apply!

• Your Mouth Guard

If your afterschool activities involve contact sports, a mouthguard is always a good idea, and especially when you wear braces. Dr. Paul Bourque, Dr. Kathy Russell, Dr. Brien Stackhouse, and Dr. Magda Barnard can create a custom guard which will protect your teeth, your delicate mouth tissue, and your braces from many impact injuries.

• Your Orthodontist’s Phone Number

One important item that takes up almost no space in your backpack, locker, or phone is the phone number for our Halifax office. If your braces are damaged, or if your aligner or retainer is lost or broken, we will let you know what to do until you can safely visit the office in person.
