The purpose of braces and other forms of orthodontic treatment at our office is to correct malocclusion, also known as crooked or crowded teeth, or “bad bites.” Past orthodontic practice dictated that wisdom teeth be removed, especially in cases of crowding.

The wisdom teeth are the last teeth to come in, and are officially known as the third molars. The teeth typically erupt, or break the surface of the skin, in young people between the ages of 13 and 20.

Sometimes, wisdom teeth are impacted. That means they cannot break through the gum tissue. This typically happens when the mouth or jaw is too small to accommodate the teeth. Impacted wisdom teeth can become infected, and some dentists and orthodontists may want to remove them as prophylaxis to prevent possible future infection.

Justification for removing wisdom teeth

Dr. Daniel Ma will tell you that in some cases, wisdom teeth attempt to come in the wrong way, either tilting in the jaw, or sideways. If the mouth is too small to accommodate these additional teeth, they inevitably become impacted. Swelling or infection of the gum flap above an impacted wisdom tooth may cause pain. The greatest danger is pericoronitis, a potentially dangerous infection that can occur in the gum area around an impacted wisdom tooth, or around a wisdom tooth that has erupted.

Orthodontists base their decision to remove wisdom teeth on each patient's individual circumstances. To learn more about the impact wisdom teeth have on orthodontic treatment, or to schedule a visit with Dr. Daniel Ma, please give us a call at our convenient Vancouver, BC office!

If Dr. Daniel Ma and our team recommend a Hawley retainer to complete your orthodontic treatment, you’re getting a classic. This retainer, invented by Dr. Charles Hawley, has been in use since the early decades of the twentieth century.

But this isn’t your great grandmother’s pink plastic retainer! The look of today’s Hawley retainer has really evolved from its early days as the “Hawley bite plate”—and pink is now a choice instead of an inevitability. In fact, you can choose from any number of colors, patterns, and designs to create a retainer that is uniquely you.

Each Hawley retainer is customized to fit your mouth and teeth perfectly. Wire clasps and a labial bow wire are securely attached to an acrylic base based on a model made from your teeth and mouth.

Your retainer is designed for function—the bow wire makes sure your teeth stay in the perfect position while your bones and ligaments get strong enough to hold them in place. The acrylic base, of course, is also functional—but that doesn’t mean you can’t have fun with it!

Retainer bases can be formed in different ways.  One type of retainer model uses pre-formed acrylic discs for the base, and these are available in many pre-formed colors and patterns. Another type of retainer builds the base by alternating several applications of liquid and powder acrylics, layer after layer. This process allows the retainer technician to create one-of-a-kind designs.

What are some of the ways to make your retainer uniquely yours?

• Color—whether deep tones, pastels, electrics, neon, or metallic, you can find an appealing shade in the color chart. Or, if you want your retainer to keep a low profile, choose a clear or a color-coordinated pink tone.
• Glow in the Dark—if you don’t want your retainer to keep a low profile, this might be just the look for you!
• Glitter—accessorize your sparkling smile with a sparkling retainer.
• Patterns—stripes, polka dots, geometric shapes—even animal patterns are possible.
• Color Combinations—why choose one color when you can have a marbled swirl of your favorites? Or a tie-dye look? Or team colors?
• Acrylic Designs—a colorful design that captures your personality is available with some creative acrylic artistry. Rainbows and flags, hearts and flowers, ladybugs, and spider webs are just some of the options on hand.
• Picture Perfect—for that special hobby, pet, team, or other personal favorite, decals or pictures can be applied under a layer of clear acrylic.

Hawley retainers are made to last, so choose your design with years of use in mind. Talk to our Vancouver, BC team about the custom looks which are available to celebrate your unique personality. After all, there’s nothing more personal than your smile!

An overbite is one of the most common malocclusions. If Dr. Daniel Ma 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. Daniel Ma 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. Daniel Ma 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 Vancouver, BC 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. Daniel Ma can provide the specific information and treatment plan you need to make that healthy bite and that confident smile a reality!  

Even though it’s called a “permanent retainer,” your fixed retainer isn’t necessarily meant to last a lifetime. But with care, it should last just as long as you need it, keeping your teeth perfectly aligned after your orthodontic treatment is complete. Why is this retainer the one to choose for challenging alignments?

A fixed retainer is often used for teeth which were very crowded or had large gaps before treatment, especially along the bottom teeth, which tend to shift more. With a permanent retainer, a custom fitted wire is attached with a bonding adhesive to the back of each of the selected teeth. This design makes sure that the teeth can’t shift out of place while your bones and ligaments strengthen around them.

Occasionally, though, your permanent retainer isn’t quite as permanent as it should be. If you think your fixed retainer is becoming “unfixed,” what clues should you look for?

• Broken wire

A clearly broken wire can be obvious, or you might discover it when you notice pain or irritation caused by the end of a wire poking around your tongue or mouth.

• Loose bond

The orthodontic adhesive used to bond the wire to each tooth can come loose as the result of an accident, an unfortunately chewy treat, or simply with the passage of time.

• Shifting teeth

You might not notice anything wrong with your retainer, but what you do notice is that your once-straight teeth have started shifting back to their old positions. If you see any movement in your teeth, your retainer might need repair.

What should you do?

• Give our Vancouver, BC orthodontic office a call! It’s important to act promptly to prevent further retainer damage, oral discomfort, and tooth misalignment.
• Rinse with warm water if your mouth is irritated.
• If a wire is poking you, call us for advice on gently pushing it back into place.
• Orthodontic wax can protect your teeth and tissue from detached wires.
• If you have a clear retainer, wear it until you can come in. If you don’t have one, and you can’t see us immediately, ask if an over the counter moldable retainer is a good idea to help keep your teeth aligned in the meantime.

One benefit of a fixed retainer is that it’s almost invisible because it’s behind your teeth. But this hidden location can also make it difficult to notice potential problems. Fortunately, there are some proactive steps you can take to help your permanent retainer—and your bite—stay healthy:

• Avoid foods which are sticky, hard, or chewy. If a food can damage traditional braces, it can damage your retainer.
• Wear protective gear like mouthguards and helmets when you’re active—they protect more than just your retainer!
• Ask your dentist to examine your retainer adhesive’s staying power whenever you have a checkup.

If you notice a detached wire or loose adhesive or see your teeth shifting, give Dr. Daniel Ma a call. It’s important to act promptly to fix a fixed retainer, because your teeth and bite alignment are in jeopardy when you delay. And always bring your retainer (or retainer pieces) with you in case we can repair it.

Permanent retainers don’t necessarily last forever. But whether your fixed retainer is going to be with you long-term, or whether you’re going to transition to a removable retainer in the future, let’s make sure your permanent retainer is just as “permanent” as it needs to be!
