The temporomandibular joint– the TMJ – is the joint in between the lower jawbone – the jaw – and the temporal bone of the head. The TMJ is accountable for jaw activity and also is one of the most secondhand joint in the body. The TMJ is basically the articulation between the condyle of the mandible and the mandibular fossa – a socket in the temporal bone. The special function of the TMJ is the articular disc – a versatile as well as elastic cartilage material that works as a cushion in between both bone surface areas. The disc lacks nerve ends as well as blood vessels in its center and also therefore is insensitive to discomfort. Anteriorly it attaches to lateral pterygoid muscle mass – a muscular tissue of chewing. Posteriorly it continues as retrodiscal tissue fully supplied with blood vessels and nerves.
The jaw is the only bone that relocates when the mouth opens up. The initial 20 mm opening includes only a rotational movement of the condyle within the socket. For the mouth to open bigger, the condyle as well as the disc have to move out of the outlet, ahead and then down the articular prominence, a convex bone surface area situated anteriorly to the socket. This movement is called translation.
One of the most usual disorder of the TMJ is disc variation, and also in the majority of the cases, the disc is dislocated anteriorly. As the disc progresses, the retrodiscal tissue is attracted between the two bones. This could be quite excruciating as this cells is totally vascular and innervated, unlike the disc. The movements made by eating or perhaps talking cause a persistent swelling to the cells leading to inflammation as well as discomfort.
The forward dislocated disc is a challenge for the condyle movement when the mouth is opening. In order to totally open the jaw, the condyle has to jump over the back end of the disc and then into its center. This creates a clicking or popping audio. Upon closing, the condyle slides back from the disc hence one more "click" or "pop". This problem is called disc displacement with decrease
In later stage of disc misplacement, the condyle stays behind the disc regularly, unable to obtain back into the disc, the clicking audio disappeared yet mouth opening is limited. This is usually one of the most symptomatic stage – the jaw is stated to be "secured" as it is incapable to open wide. At this stage the condition is called disc variation without reduction.
Luckily, in bulk of the instances, the problem fixes on its own after time. This is many thanks to a process called natural adaptation of the retrodiscal cells, which eventually comes to be scar tissue as well as could functionally replace the disc. Actually, it ends up being so much like the disc that it is called a pseudodisc.

    I hope someone will see my post and advise. Thanks!
    So, last night I had in-ear headphones into my ears and I was listening to
    music. At some point, I felt that my right in-ear has dropped so I tried to
    put it back and push it into my ear – in the same time I think I yawned or
    opened my mouth – and in that exact same moment I felt a really awful pain
    right next to my right year – I believe at the temporomandibular joint.

    This morning, when I woke up I had pain the right side of the joint, I had
    pain on the right side when I tried to chew + when I was yawning or opening
    the mouth wide I was feeling some sort of discomfort on the right side.
    It’s like the bones from my jaw don’t properly match on the right side,
    when I open the mouth wide and then close it my jaw has a weird zig-zag
    move from left to right (it’s like I have something close to the TMJ, like
    it has increased or something).

    Now I don’t feel any pain anymore, just that TMJ zi-zag movement of the jaw
    when I yawn or open the mouth + discomfort on the right site. On top of
    that, both of my ears feel really weird, like they are clogged. I hope I
    haven’t displaced my mandibula or broken that joint. 🙁

    I’ll try to go to a doctor this Monday. I hope I won’t need surgery… :(

      If you can’t open without deviating to one side it is probably because the
      joint is locked on one side only. I would see your dentist about it.


    January 3, 2016 at 12:04 pm

    Pls help, my right jaw has this problem. When I try to move it inward
    (left) it get’s blocked or locked, if I keep pushing it. Then I hear a
    crack knuckle like sound, and i’m able to move my jaw again. Later, the
    whatever comes back and I can’t move my right jaw inward again, so I do the
    same thing, just keep pushing it and break that force that holds it back.
    The blocker comes back once every like day. But it’s been a few months, and
    it comes back less often, maybe once every 3/4 month or more. So that’s
    good, BUT I have noticed my right jaw looks bigger, bulgier, and a bit un
    even, compared to my left jaw. It is unattractive. :(

      I think I went through that process too, several years ago. You maaaay be
      showing early symptoms of a tmj issue. At the least, try to eat softer
      foods. And as for the jaw looking bigger? I’ve got the same issue. I got an
      x-ray of my head and my jaw was more misplaced than the other side so yeah.
      Take the info how you will, it’s just something to help to think about.

    I have had TMJ for most of my life and it’s limited a lot of things I can
    do. At the moment my wisdoms are growing in and it’s very painful. The pain
    gets so bad I get really bad migraines that I have to lock myself in a
    pitch black room with absolutely no sound. This is not new, usually my
    migranes put me in this condition but it’s rare when my jaw gets locked
    open or shut. For the past few days my jaw has locked open when I eat(soft
    foods only such as ramen or bread. just bread) or when waking up. It’s
    getting to the point I can’t hide the pain, and I have a high pain
    tolerance. I pop pain pills like candy and my wisdoms aren’t grown out
    enough to be pulled. I do exorcises when I can, but those are painful too.
    I apply hot rice packs to the joint and nothing helps. I can hardly talk
    anymore and in order to talk I have to keep my mouth damn near shut. I
    can’t take this pain anymore and it’s interfering with my life. What can I
    do to make it stop??

      I’ve sought after some help and there’s limited options, unfortunately. The
      first option to help with the wisdom teeth is getting them pulled out
      regardless if they’re developed or not. I had to get mine removed because
      of my tmj issues so the dentist removed my wisdoms by digging for the
      fragmented shards. Granted, there was more blood than the average patient
      but it helped. The second option is to undergo surgery and there’s no way
      in hell my insurance would allow that but it may be an option for you. And
      lastly, live with it. Because the wisdom teeth removal only helped for a
      few days and because my medical insurance didn’t cover the surgery, I’ve
      gotta with it until my jaw falls off. So try one of those options if you
      must but be hopeful. Hope for the best but expect the worse, my mom always

      February 18, 2016 at 10:59 am

      +Marcos Sanchez Thank you so much, I’ve been scared to get them removed
      since I can only open my mouth two fingers width, but if it helps I will.
      Did you have to see a special dentist or can a basic dentist do it?

    • Marcos Sanchez

      February 18, 2016 at 4:01 pm

      +Jacqueline Quinn I went for a dentist to have the damned tooth shards
      removed but afterwards I went to see an ent (ear nose and throat) doctor to
      further examine my jaw. I’m glad to at least be of some help

      when my jaw is clicking if I only open it widely?

    Um I’ve had this for about 4 years, not the locking, just the discomfort
    and clicking, which is the most uncomfortable part. All non-surgical
    methods have failed, and I will have surgery if necessary it’s just that
    it’s most common in 20-40 and I’m only 15. Any advice?

    • Alila Medical Media

      May 2, 2016 at 6:31 pm

      +Daniella Araujo If your teeth are mis-aligned you may want to consider
      getting braces. Misalignment of teeth may cause TMJ problems, also check if
      you grind your teeth at night and address that. I would avoid surgery as
      much as possible, it may do more harm than good.

    • Daniella Araujo

      May 2, 2016 at 7:39 pm

      +Alila Medical Media I have braces at the moment and it began far before
      them and as far as teeth grinding it is definitely a possibility but
      assuming the plate solution to reduce grinding doesn’t work, what other non
      surgical options should I consider

    Hi Alilia,
    I had clicking on one side for 2 years (came out of no where)… then it
    all of a sudden stopped a couple months ago. When my one side was still
    clicking my MRI showed that both of my discs are displaced but reduce
    appropriately… my opening has always been great so I’m confused as to
    what could be happening. I have lots of physical therapy on my muscles.
    Could the disc be recaptured? Can your opening still be great if the disc
    is displaced without reduction? I had the MRI and then two weeks later is
    when it stopped popping and hasn’t popped since (sometimes when I brush my
    tongue – theres slight crack sound when I open wide) or else I would have
    gotten another. My doctor told me my pain is muscular.

    • Alila Medical Media

      May 4, 2016 at 5:58 pm

      +Emily Hill If the clicking stopped and you can open normally, you probably
      got your pseudodisc formed, which is great. If you still have pain, it’s
      likely to be muscular like your doctor said. You can watch this video to
      understand more :

    So if I hear a clicking noise around the TMJ but no pain, jaw restrictions
    or soreness, should I have nothing to worry about? Or will it get worse in
    the future? Will it go away? Whenever I step I hear crackling in my ears
    due to the tmj and its very annoying, I hope it goes away soon.

    If the scar tissue becomes similar to the disk will it still click? Ive had
    tmj for years and my jaw pops twice on both sides snd its still does it.

    • That One Guy

      June 21, 2016 at 3:05 pm

      Go to a jaw specialist. If it’s been years there’s a high chance that the
      disks will never go back in and you will need monthly check ups for the
      specialist to put it back in place. This happened to my mom on both sides
      and now the slip out all the time and she always need sit to get put back

    June 29, 2016 at 11:25 pm

    Could this have anything to do with braces? I got TOP ONLY braces 6 months
    ago and a few days after, I had a sore jaw and experienced clicking as I
    closed my jaw as well and sharp pains. Could this be from the braces?
