Jaw Ache Muscle

The temporomandibular joint the tmj is the joint between the lower jawbone the mandible and the temporal bone of the skull. The TMJ is responsible for jaw movement and is the most used joint in the body. The TMJ is essentially the articulation between the condyle of the mandible and the mandibular fossa a socket in the temporal bone. The unique feature of the TMJ is the articular disc a flexible and elastic cartilage that serves as a cushion between the two bone surfaces. The disc lacks nerve endings and blood vessels.

In its center and therefore is insensitive to pain. anteriorly it attaches to lateral pterygoid muscle a muscle of chewing. Posteriorly it continues as retrodiscal tissue fully supplied with blood vessels and nerves. The mandible is the only bone that moves when the mouth opens. The first 20 mm opening involves only a rotational movement of the condyle within the socket. For the mouth to open wider, the condyle and the disc have to move out of the socket, forward and down the articular eminence, a convex bone surface located anteriorly.

To the socket . this movement is called translation. The most common disorder of the TMJ is disc displacement, and in most of the cases, the disc is dislocated anteriorly. As the disc moves forward, the retrodiscal tissue is pulled in between the two bones. This can be very painful as this tissue is fully vascular and innervated, unlike the disc. The forward dislocated disc forms an obstacle.

For the condyle movement when the mouth is opening. in order to fully open the jaw, the condyle has to jump over the back end of the disc and onto its center. This produces a clicking or popping sound. Upon closing, the condyle slides back out of the disc hence another click or pop. This condition is called disc displacement with reduction . In later stage of disc dislocation, the condyle stays behind the disc all the time, unable to get back onto the disc, the clicking sound disappeared but mouth opening is limited.

This is usually the most symptomatic stage the jaw is said to be locked as it is unable to open wide. At this stage the condition is called disc displacement without reduction Fortunately, in majority of the cases, the condition resolves by itself after some time. This is thanks to a process called natural adaptation of the retrodiscal tissue, which after a while becomes scar tissue and can functionally replace the disc. In fact, it becomes so similar to the disc that it is called a pseudodisc.

7 Most Painful Dental Conditions Ever How They Will Kill You

These are the seven most painful dental conditions ever. after watching this, you’ll be scared shitless about your next trip to the dentist. Number 7: Dental Abscess A dental abscess is an infection inside the tooth or the gums that’s filled with pus. If not treated properly, it has the potential to turn deadly. While there are a few different types of abscesses, they generally all have similar symptoms. The pain involved with an abscess usually starts off mild, but can quickly become extremely.

Painful. the pain has been described as a throbbing or shooting sensation. the area in question will also swell up turn red. In more extreme cases, the abscess may spread to the bones tissue near the teeth, which could cause swelling in the face or lymph glands on the neck. The pain will then spread to the side of the face near the toothache. If a severe abscess were to go untreated, it could eventually spread internally to tissues muscles near the infected area. This spread can lead to a dangerous condition known as.

Ludwigs angina, or an infection occuring on the floor of the mouth. this disease can be deadly as it often restricts necessary airways. In fact, the name angina is derived from the Greek word ankhon, meaning strangling. In addition to feelings of being strangled, the face, neck, head will also become infected. It is even possible for people to die from an abscess. Famous fashion designer notorious Nazi supporter Hugo Boss died from a tooth abcess in 1948. A 12yearold boy named Deamonte.

Driver died from a tooth abscess as well when it spread to his brain. despite two operations six weeks in the , his life could not be saved. The same thing happened in 2011 to 24yearold Kyle Willis when the infection spread to his brain caused it to swell. In the cases of both Driver Willis, a delay in treatment was due to the fact that neither of them had health insurance. Number 6: Periodontal Gum Disease Periodontal gum disease is the result when.

Gingivitis goes untreated. it appears as inflammation infection around the tooth when severe enough, can cause tooth loss damage to your bone structure. Once your gums are infected, they begin pulling away from the tooth. This space allows bacteria to form underneath the gums. It’ll then progress by badly damaging the bone structure under the gums usually results in teeth falling out or being removed if not treated properly. Symptoms of periodontal gum disease include sensitive teeth, bleeding gums, swollen gums,.

Loose teeth, painful chewing. it is often the result of smoking, hormonal changes, or a byproduct of other diseases such as diabetes or even AIDS. Number 5: Edentulism Edentulism is a condition in which one is either completelyor at least partiallytoothless. It affects an estimated 158 million people worldwide. As we all can suspect, losing ones teeth can be very problematic. Teeth serve many.

Basic yet important functions such as chewing food, maintaining speech, supporting your facial structure. Teeth also allow humans to break their food down in a manner that is more digestible through a process known as mastication. As a result, malnutrition is a very possible side effect, which may additionally have a domino effect. Weight loss, constipation, arthritis have been known to occur as well. In the most extreme cases of edentulism, the condition has even been connected to more serious sometimes.

Lifethreatening diseases such as parkinsons disease, heart problems, even cancer. Number 4: TMJ Conditions Temporomandibular joint dysfunction, or TMJ, describes a condition in which three important parts of the mouth experience pain: the muscles that move the jaw, the muscles of mastication, the temporomandibular joints (which connect the mandible to the skull). If left untreated, TMJ conditions can become chronic quite painful.
