Temporomandibular joint disorders (TMD) describe a set of conditions that involve trouble with your jaw and face muscles. They result from a problem in the temporomandibular joint (TMJ), which is a hinge that connects the temporal bones, in your skull in front of each ear, to your jaw. The joint enables you to talk, yawn, and chew by letting your mouth move.

TMD can be very painful and interfere with functions such as eating and speaking. This what to watch for and how to try to prevent TMD.

Risk Factors for TMD

You are at higher risk for TMD if you are a women than if you are male. The disorder is most common among adults between the ages of 20 and 40 years. Other risk factors for TMJ disorders include the following.

• Arthritis in the area, making movement more difficult
• Excessive tooth grinding, because it increases stress on the joint
• General stress, which can lead you to clench your teeth and strain facial muscles

Symptoms of TMD

Symptoms of TMD can last for just a short while, or for several years. Seeing Dr. Cronin is important if your symptoms make it impossible for you to eat regularly or if you have unbearable pain or discomfort. The following symptoms can occur on both or one side of your face.

• Aching or very tired facial muscles
• Jaws that are fixed open or shut without you being able to unlock them
• Grating or popping sounds when you chew or close or open your mouth
• Pain in the entire area, including the mouth, jaw, neck, or shoulders, that comes on when you chew or yawn

Preventing TMD

You can try to prevent TMD by focusing on reducing risk factors. If you grind your teeth at night, ask Dr. Cronin about wearing a mouthguard. If you are overly stressed, look into ways to better manage your stress and relax your muscles. Another strategy for trying to prevent the development of TMD is to avoid chewing gum, since that puts stress on your jaw.

If you have questions about TMD, don’t hesitate to contact our Langley office.

Wearing braces limits some of the snacks you can eat. However, you still have plenty of choices for fun and healthy foods that will not harm your braces. You can even enjoy a few crunchy treats as long as you choose them carefully.

Sweet Treats

Puddings provide a sweet and safe snack while you are wearing braces. You can even select flavored puddings such as caramel to satisfy the urge for items you should not eat. They can be purchased already made or whipped up at home. You can even select low-sugar varieties that still taste good. Ice cream and yogurt are also choices; just avoid products with nuts.

Healthy Snacks

Fruits are excellent for a healthy snack. You just need to avoid biting into hard fruits such as whole apples. You can avoid the problem with fruit cocktails packed in water. Cocktails still have the nutritional benefits and flavor, but contain softer pieces. Avoid fruits packed in heavy syrup, though; these tend to have too much sugar.

Crunchy or Salty Snacks

Not all crunchy foods are bad; you just need to limit the crunch. Walnuts are a softer nut that can normally be eaten safely. Small cheese crackers satisfy the need for crunchy and salty. You can also allow pieces to dissolve slightly in your mouth before chewing, to reduce any risk.

Soft granola bars are also an option. Check the granola ingredients to ensure there are no large nut pieces, and brush your teeth afterwards. Otherwise pieces can become stuck in your dental work.

If you have any questions about safe snacks, do not hesitate to ask Dr. Cronin and our staff.

One of the most common reasons for getting braces is because there’s just not enough room for all your teeth to fit next to each other evenly. The result is overlapping and crooked teeth. What’s the first step in creating the space you need? Well, that depends on just how much room you need to align your teeth and bite properly.

When there is going to be a serious need for space, there are orthodontic solutions that can help, including palatal expanders, surgical options, and extractions. But if you only need a tiny bit of room so that regular braces will fit properly, we have a tiny solution—orthodontic spacers!

Why do you need to make space before you get braces? Because Dr. Cronin might need to make some room around crowded molars so your braces can be installed properly.

For example, you might need orthodontic bands to anchor your braces. An orthodontic band is a slim, custom-fitted ring of metal which fits snugly around a molar. It is durable, provides a place to attach bands and springs to help correct malocclusions (bite problems), and can securely surround a tooth that might be weak because of a large filling. Spacers can separate crowded teeth just enough to allow a band to be fitted around a molar.

Even if you don’t need bands, sometimes separators are necessary to provide enough space between the teeth for your braces to work effectively. The back teeth tend to move even closer together with braces, and, without adequate space, bite problems, risk of decay, and other difficulties can arise.

And while you might think that some serious equipment is in order to make room between those sturdy molars, the typical spacer, or separator, is actually extremely simple--usually a tiny, round elastic band, often made of rubber. Spacers can be placed between tight teeth in a matter of minutes. Each ring is stretched and positioned between your teeth with a special tool. As it returns to its original shape, the spacer’s width provides just enough pressure on the teeth it touches to make a bit of space between them. And a bit of space is usually all you’ll need.

What do spacers feel like? For some people, they can be uncomfortable. You might feel soreness, some pressure, or as though a piece of food is stuck between your teeth. Ask us for suggestions on making you more comfortable, whether it’s dining on ice cream and cold drinks, eating soft foods, or taking over-the-counter pain relief. Separators are only designed to be in place for a very short period (usually under two weeks), but if they are causing you pain, give us a call.

What do you need to do to help the process along? Actually, it’s more what you need not to do. Don’t use dental picks or floss on your separators, avoid chewing gum, and take chewy and sticky foods off the menu. And don’t be tempted to touch or play with your spacers!

Spacers can create space between the teeth so quickly and efficiently that they often fall out on their own after a few days. If your separators fall out, give our Langley office a call. It could mean that you are ready for your braces, and on the way to a lifetime of healthy, beautiful smiles. And it’s a journey that begins with a tiny, springy step.

The term malocclusion refers to misalignment of teeth. You may have been born with malocclusion, so your teeth simply grew in crooked, or the misalignment and crowding of your teeth occurred over a period of time. Either way, not only can malocclusion pose cosmetic issues, but it can have a negative effect on your speaking and eating abilities as well.

Types of Malocclusion

Malocclusion encompasses multiple types and classifications of misalignment issues, including twisting or rotation of the teeth and molars that do not meet when you bite down. In some cases, the top front teeth are pushed outward in an upper protrusion.

In other cases, a misplaced midline results when the front top teeth don’t meet with the front bottom teeth. Transposition occurs when teeth protrude through the gums in a position where another tooth is supposed to be.

Practically any type of crowding or spacing issues, rotation or twisting of the teeth, or bite problem – including overbite, underbite, open bite, or crossbite – is included under the umbrella of malocclusion.

Malocclusion Classifications

There are three classifications of bite or misalignment problem.

• Class 1 malocclusion: While the bite may be normal, the upper teeth overlap the lower teeth slightly. This is the most common type.

• Class 2 malocclusion: Known as overbite or retrognathism, class 2 involves a severe overlap of the upper teeth and jaw over the bottom teeth and jaw.

• Class 3 malocclusion: Known as underbite or prognathism, class 3 occurs when the lower teeth and jaw overlap the upper teeth and jaw. Thus, the lower jaw juts forward.

Causes of Malocclusion

The most common cause of malocclusion is genetics. However, there may be other causes, including the development of abnormally-shaped teeth, lost teeth, or impacted teeth; thumb sucking or overuse of a pacifier as a small child; having fillings or crowns that do not fit correctly; a serious injury that causes misalignment of the jaw; or developing a tumor of the mouth or jaw.

Treating Malocclusion

Orthodontic care at Cronin Orthodontics with Dr. Cronin is the main treatment available for malocclusion, which includes getting braces, Invisalign, or other corrective treatments. Treatment is ideal not just to have your smile improved, but because it makes the teeth easier to clean and maintain, lowers the risk of gum disease and tooth decay, and can even take pressure off the jaw and teeth.

Think about orthodontic treatment if you (or your child) display any signs of malocclusion. Early treatment of malocclusion during childhood can lessen expensive treatment later on.
