The term TMD means “Temporomandibular Disorder.” But if you suffer from this disorder, it means pain. The pain can be mild or severe, acute or chronic, and it can appear to be centered in different locations, making it difficult to diagnose.
People who clench or grind their teeth because of stress often experience the pain of TMD. They might not even know they are engaging in these habits, because they do them subconsciously, for example when driving in traffic or engaging in vigorous exercise. Another cause of TMD might be an injury such as a blow to the jaw.
You can feel your temporomandibular joints working if you place your fingers in front of your ears and move your lower jaw up and down. On each side the joint is composed of an almond shaped structure at the end of the lower jaw, called the condyle, which fits neatly into a depression in the temporal bone (the bone on the side of your skull near your ear). A small disc between the two bones allows the lower jaw to move forward and sideways. The joints are stabilized by ligaments and moved by muscles.
TMD pain is the result of a process that begins when a stimulus such as psychological stress or an injury to the joint causes spasms (involuntary muscle contractions) in the muscles that move the joint. Blood vessels in the muscle begin to accumulate waste products, causing chemical changes and lactic acid buildup in the muscle. Nerves in the muscle then signal the brain to stop the movement of the jaw by registering pain.
TMD pain can appear to originate from various locations in your jaw, head, or neck. This is why it's important to make an appointment with our office for a professional assessment and diagnosis.
Treatment aims to relieve the symptoms of pain and discomfort and to prevent them from recurring in the future. Treatment can include heat, mild painkillers, muscle relaxants, soft diet, and simple jaw exercises, as well as education regarding the causes of TMD. To prevent further pain you may be provided with a “bite guard,” or referred to relaxation training with a licensed therapist. A bite guard is designed to prevent the lower teeth from biting hard into the upper teeth. It is commonly worn at night, but can also be worn during the day if clenching and grinding are apparent.
If these simpler treatments do not solve the problem, we may recommend more complex procedures such as bite adjustment or, as a last resort, surgical treatment may be needed.
When speaking about veneers in dentistry, many people wonder what they are really made from and how they produce such natural results. The answer is dental porcelain...and yes, it really is a type of porcelain or glass. Even though they are made of porcelain, not all porcelains are the same. This is one reason there can be such a wide price range when comparing porcelain veneer pricing from one dentist to another. For example, the quality of the dental porcelain used and the expertise of the dental lab artisans greatly impact the price of a veneer — just like other pieces of fine art, pricing depends upon the materials used and the artistry of the person creating them.
Dental porcelains are used to create veneers because of their near ideal optical properties in mimicking natural teeth in shine, opacity, and translucence. And when you combine these facts with the artistry of the lab technician and your dentist skill's in placing the veneers, you begin to understand how veneers are virtually undetectable in cosmetically-enhanced teeth. Another reason for using dental porcelain is that they can be made in many colors, shades and translucencies to enhance the optical properties and natural beauty of whiter, brighter, and visually appealing teeth. However, do not let the word porcelain, fool you when it comes to durability. While veneers are not as strong as natural teeth they are not so fragile that you should worry about breaking or damaging them with normal wear and tear. However, you should avoid biting into extremely hard substances; using your veneers as a tool in lieu of scissors, tweezers, or pliers (you should not use your natural teeth as a tool either!); and twisting your veneers when biting into harder substances.
Your teeth were designed to last you a lifetime, so you should do everything you can to protect them. This includes guarding them against dental erosion. However, many people may not know for sure what dental erosion is, much less how or why they need to guard against it.
Dental or tooth erosion is the irreversible loss of tooth enamel from chemical attack by acids. Eating or sucking acidic foods such as lemons is a good example. But most people are shocked to discover that it can also be caused by their favorite sodas (carbonated beverages), natural fruit juices, energy and sports drinks — especially with excessive consumption. It takes the saliva, nature's protection, at least 30 to 60 minutes to neutralize the effects of acid, so only one acidic drink an hour causes your teeth to be continually bathed in acid. And this is an important fact to know, because if your mouth is acidic all the time, this will promote tooth decay.
Will brushing help out with prevention?
When it comes to dental erosion, brushing immediately after acid consumption can actually make it worse by accelerating the erosion process. This is because the acids in these drinks (and some foods) actually dissolves tooth enamel and softens the tooth surface. These newly softened surfaces can literally be brushed away if you brush before your saliva has a chance to try to reverse the process. If done often, you could even brush away your enamel! For this reason, you should wait at least 30 to 60 minutes before you brush your teeth after consuming any of these products.
So what can you do to prevent dental erosion?
One important step that you (and your family) can do to help prevent dental erosion is to limit the amount of these beverages you drink. Instead, try drinking calcium-rich milk or water and saving your favorite acidic beverage for a special treat that you consume preferably with a meal. Try reducing the number of these drinks you consume over a period of time. If you must drink an acidic beverage avoid swishing it in the mouth and use a straw to reduce the contact between the acid and your teeth.
Just remember that once your dental enamel has eroded, it is gone forever. So you should follow these simple tips now to protect your smile and future.
