Now that you’ve graduated from your braces or aligners, you might think you’re finished with orthodontic cleaning tips. Not quite yet! Your retainer needs love, too—not just because it can look or smell “less than appealing” without your help, but because it’s good for your dental health.

Removable Retainers

If you have a Hawley retainer or a clear retainer, cleaning it whenever you remove it is a great idea. Unappetizing white patches mean plaque or mineral deposits from your saliva have dried and hardened on your retainer’s surface. And if you notice an unpleasant taste or odor, it probably means that germs and bacteria have made themselves at home and are growing in and on your appliance.

You don’t want old plaque or new bacteria in your mouth! Here are some ways to keep your retainer clean and fresh:

• After wearing it, you can clean your retainer with a toothbrush, but don’t brush too vigorously. You might scratch it. Use a soft or even extra-soft brush to clean out all the nooks and crannies, and then rinse.
• Use cleaning products which have been recommended by Dr. Daniel Ma if your retainer needs a deeper clean. Denture cleaners, retainer cleaners, and even toothpastes can be too abrasive or cause discoloration, so use the products made for your specific retainer.
• Let your retainer dry before storing it in a dry place after cleaning. Shutting a damp retainer into a closed case provides bacteria with the damp, dark environment they thrive in. (PS—clean your case regularly, too!)
• One of the benefits of a clear retainer is that it’s almost invisible. And you can help keep it that way by removing it whenever you eat or drink. Your retainer can become stained from colored foods or liquids.

Fixed Retainers

A permanent retainer is a small piece of wire that is custom-fit and bonded to the inside of selected teeth to keep them from shifting. Because food particles and plaque can accumulate around a fixed retainer, brushing after meals and at least twice a day is recommended. Bacteria and plaque cause bad breath, cavities, and tartar buildup, and removing tartar might require removing your retainer.

While a fixed retainer can be tricky to clean, there are techniques and products that make cleaning easier and more effective:

• An orthodontic toothbrush with a smaller head might reach behind your teeth more comfortably.
• Don’t forget to floss! Using a floss threader will help you get that wriggly floss behind the retainer and between your teeth.
• Try a water flosser. These handy devices direct a stream of water right into hard-to-reach places for more thorough cleaning.

If you’re having trouble keeping your retainer clean, our Vancouver, BC orthodontic team can teach you all you need to know about tools and techniques to keep your retainer—and your teeth and gums—healthy. An attractive smile is a great thing. A healthy, attractive smile is even better!

You’ve been told that you have a malocclusion called an “underbite.” Let’s look at just what this diagnosis means, and what it means for you.

Just what is an “underbite”?

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 typical bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth.

An underbite, on the other hand, 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.

What causes an underbite?

Underbites tend to be genetic, and run in families, so, most often, an underbite is something you’re born with. The size of your jaws, the shape of your teeth, or both will affect your bite.

A smaller number of underbites develop because of injuries or early oral habits, such as prolonged and vigorous thumb sucking or tongue thrusting.

How do we treat an underbite?

Your treatment will depend on the type and severity of your underbite, and your age when treatment occurs.

• Braces and Aligners

If your underbite is a slight one, caused, for example, by crowded or overly large teeth, braces or clear aligners can help move the teeth into proper alignment.

• Functional Appliances

If the underbite 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 growing and forming.

If you’re a young patient, two appliances commonly used to help correct an underbite are palatal expanders, which gradually widen the upper jaw if it’s too narrow, and reverse pull headgear, which fits both inside the mouth and outside on the face, and provides a steady, gentle pull to encourage the forward growth of the upper jaw.

• Surgical treatment

In some severe cases, surgical treatment can correct an underbite by reshaping the jawbone itself and positioning it further back to align properly with the upper jaw.

Why treat your underbite?

A serious underbite can cause damaged teeth and enamel, painful problems with the temporomandibular joint, headaches and facial pain, sleep apnea, difficulty chewing, eating, and speaking, and can affect confidence and self-esteem.

By following your treatment plan, you’ll not only prevent these consequences, but you’ll achieve major benefits—a healthy, comfortable bite, and an attractive, confident smile. Want to know more? Talk it over with Dr. Daniel Ma at our Vancouver, BC office for all the information you’ll need!

Congratulations! You’ve done the hard work necessary to create your beautiful smile! You’ve carefully completed all the steps needed to reach the end of your orthodontic journey. Well, nearly all the steps. We can’t forget that last step which will ensure that all your hard work is rewarded.

When you first began orthodontic treatment, Dr. Daniel Ma decided on the best plan for straightening your teeth and perfecting your bite, whether you wore traditional braces, lingual braces, aligners, or other orthodontic appliances. And now that you’re finishing treatment, there’s one more option to consider—your retainer.

Why do I need a retainer?

While you’ve spent time in treatment, more has changed than just the position of your teeth. The periodontal ligament, the connective tissue that connects the teeth to the jawbone, is stretched as the teeth shift. The bone in your jaw changes, too, reforming and rebuilding around the roots of your teeth as they move to their ideal locations.

These changes happen because your braces or aligners apply gentle, constant pressure to move your teeth. When you’ve finished wearing these appliances, the pressure stops. Ligaments will try to return to their original shape, which can shift teeth back toward their old positions. And the rebuilding bone isn’t dense enough yet to stop teeth from shifting due to the normal, everyday pressures of eating, chewing, and smiling.

A retainer prevents your teeth from moving back, or “relapsing,” by giving your bones and ligaments time to stabilize and rebuild. The process takes months, so keeping your teeth in place as bones rebuild and grow denser is crucial. This is especially important for patients with more serious misalignments. Dr. Daniel Ma will let you know which kind of retainer will be best for you and just how long you’ll need to wear your retainer.

Are there different kinds of retainers?

There are! Retainers can be removable or fixed, visible or nearly invisible, metal, plastic, or metal and plastic. Three of the most popular retainer options include:

• Hawley Retainers—the traditional removable retainer, which uses a molded acrylic plate with wires attached to keep your teeth properly aligned and to hold your retainer in place.
• Clear Plastic Retainers—a removable retainer made of custom vacuum-formed plastic, which fits over the teeth like a clear aligner.
• Fixed Retainers—a small single wire bonded to the back of specific teeth, which holds them in place and prevents any movement.

Dr. Daniel Ma will let you know whether a removable or fixed retainer is best for making sure your teeth don’t start to relapse, and fill you in on the benefits and care of each type of retainer.

How long do I need to wear a retainer?

There’s no standard answer to this question. Just like your retainer is custom-built to fit your individual teeth, the amount of time you’ll spend in that retainer depends on your individual needs. Retainers might be worn fulltime for months or years, be worn only at night after several months of daily wear, or be worn long-term to make sure your orthodontic work lasts.

Because you’ve done the hard work already, and your beautiful, healthy smile is the result. Talk to a member of our Vancouver, BC team about which retainer option will be best for making sure that this smile lasts a lifetime.

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 Vancouver, BC 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. Daniel Ma for expert advice.
