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. Todd Hamilton 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. Todd Hamilton 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 Denver, NC office.

Xylitol is a naturally occurring sweetener found in tree bark, plants, fruits, and vegetables. The human body also produces it in small amounts. It looks and tastes like sugar, so as part of a health regimen, most people require no willpower to use it.

Xylitol is safe (approved by the World Health Organization) because only a small amount is needed for health benefits. With a glycemic index of seven, it is safe for diabetics. It has less than three calories per gram and 40% fewer calories than other carbohydrates. If eaten in extremely large amounts too quickly, it has a laxative effect in humans.

Tooth decay happens when bacteria in your mouth consume the sugars you eat. When you eat food that contains ordinary sugar, it gives energy to the bacteria on your teeth, allowing them to multiply and start making acids that destroy the enamel on the teeth.

Since xylitol is a natural sweetener derived from the fibrous parts of plants, it does not break down like sugar, so it helps maintain a neutral pH level in the mouth. Xylitol also prevents bacteria from sticking to the teeth because they are unable to digest it. That is how it protects the teeth from cavities.

With xylitol, the acid attack is diminished. With less bacteria and acid, your teeth stay healthier. The frequency of xylitol ingestion is important: aim for five grams a day, or one gram every three hours.

Studies of xylitol use as either a sugar substitute or a small dietary addition have demonstrated a dramatic reduction in new cavities. It has also stopped and even reversed some existing cavities. This effect is long lasting and possibly permanent. Low cavity rates persist even years after the trials have been completed.

Xylitol needs to be one of the first ingredients in a product to be effective. It is convenient and easy to use. You can find it in health food stores and specialty grocery stores. Xylitol can be delivered to your teeth in chewing gum, tablets, or even candy and mints.

It also comes in toothpaste, mouth rinse, baby oral wipes, gel and pacifiers, nasal wash, dry mouth spray, a granulated form for cooking, granulated packets to add to drinks, and commercially prepared foods. It can replace sugar on a one-to-one ratio.

Sweet rewards in xylitol are good for the body and the teeth! If you have specific questions please feel free to contact Hamilton Orthodontics. We look forward to seeing you soon!

It's a moment many of our patients have experienced. One second you're chewing on a piece of gum, then suddenly you forget to keep chewing and swallow the entire rubbery gob whole! It's at this point you remember your mother warning you as a child that if you swallow gum it will stake a claim and take up residency in your belly for seven years. Dr. Todd Hamilton and our team at Hamilton Orthodontics hate to take all the fun out of the mystery, but the truth is that chewing gum, when swallowed, will enter your stomach and move through your digestive system just like any other piece of food. So, if you ever accidentally swallow a piece of gum, there is no need to worry!

That being said, it's important to know that gum does not have any dietary benefits, so while it’s not exactly harmful to swallow, you still want to avoid swallowing it. If you are an avid gum-chewer, we encourage you to chew sugarless gum, especially if you are wearing braces, because gum with sugar can lead to cavities. Sugarless gum still has the same amount of flavor, but has fewer cavity-causing ingredients. In fact, many brands contain an additive called xylitol, a natural sweetener known to fight cavity-causing bacteria. Xylitol is also known to increase salivary flow as it rinses away plaque and acid.

The fact is, when the bacterium in your mouth breaks down sugar, what’s left behind is acid. This acid eats away at the enamel coating of your teeth, causing holes that we call cavities. Cavities can lead to other long-term mouth problems if they are not treated in time, so it is best to try and avoid overexposing your teeth to too many harmful substances!

If you have any questions about chewing gum, please contact our office. Happy (sugar-free) gum chewing!
