Bruxism caused mouth to not open wide?

Hi

Has anyone else experienced that they couldn't open their mouth properly due to bruxism ie teeth grinding & clenching?

My mouth suddenly wouldn't open past 2cms & I have struggled over the past months since to try and figure out what has caused it. I have had an MRI which suggested nothing was wrong with my disc & that it's probably muscular tension caused by my bruxism problems.

I have no actual pain in my jaw/cheeks, but I have a feeling of tightness all around my jaw which means I can't open wide and I can no longer move my jaw very much side to side.

I would really like to hear from others who have bruxism and have experienced limited mouth opening primarily due to their grinding/clenching?

Re: Bruxism caused mouth to not open wide?

Hi,
I have been a night grinder/clencher for 5 or 6 years at least. Only recently have I been experiencing a limited ability to open my mouth - the oral surgeon I went to called it a "closed lock." Mine is accompanied by additional TMD pain and symptoms. Do you have any jaw clicking or popping when you try to open wider? Do you wear a bite guard at night? I am rather ambivalent about mouth guards, but I know many dentists and specialists swear by them.

Hi Merricat

No I don't get any clicking or popping when I open my mouth. At the moment I can only open around 2.5 cms- I literally can't open any wider- I just feel a tightness/resistance as if my mouth is incapable of opening further.
I have been wearing a 'full arch splint' which covers all my upper teeth but it just protects my teeeth's surfaces & I can still clench down.

Do you experience clicking? How long has your mouth not been opening properly? It's been 6 months for me. My opening varies from 17mm to 27mm, but varies day to day. The past 2 weeks have been extremely stressful for me & I know I have started clenching badly again & my opening is smaller.

I'd like to hear how you're going and any progress you're making

Hi Violet,,sorry to hear your condition. PLease be careful wearing an upper splint, I dont' know anyone on healthboards who has gotten relief from those. They let your lower jaw slide all over and especially further back when you sleep. Maybe you should ask your doc. if he thinks it's time to try a lower full arch splint. I know a lot of doctors in the states and Canada use those with success, and they are against upper splints. I hope you get relief soon, muscular spasms can definitely make it harder to open. Try gently massaging inside your mouth, almost squeeze those muscles tight, until you can't stand it anymore, this will break up the spasms to a degree. (No long fingernails here) hee hee.. Take care---J.

Hi Violet,
Yes, I do have clicking on both the right and left sides as I close my mouth if it has been open wider than 1.5cms or so. My mouth opening has been limited for about 3 months - since the muscle pressure and pain started. I am going to physical therapy and also to a craniofacial pain center. So far, no miraculous results, but I am hoping that it is just a matter of time and persistence. My current opening range varies from 31-34mm and I feel the same resistance that you do - just the feeling that it is not possible for my jaw to open any more.

I do now have two separate splints - one for the daytime and one to wear at night. The night splint is really just a mold of my teeth, with some additional fill right over my front four teeth or so. The dentist explained that since the molars generate the most force/pressure on the muscles and joints, the idea is to limit the clenching to just the front teeth so that you cannot do as much damage to your jaw. He did not, however, recommend the NTI device that you will see advertised sometimes.

Additionally, I have been prescribed a muscle relaxant (flexeril), but do not take it regularly since I am not convinced that it did more than just make me groggy, and I like to take as few medications as possible. You might also try a Magnesium supplement, which is good for muscle relaxation.

Re: Bruxism caused mouth to not open wide?

Sounds like your TMJ meniscus is displaced anteriorly in the joint capsule and causing your limited opening. At this point there would be no clicking or popping.

i would seek out a dentist who has a lot of TMJ experience.

I am a retired dentist who treated many TMJ patients during my professional career .

Re: Bruxism caused mouth to not open wide?

Hi Violet,

I too have a limited mouth opening, the same as yours about 2.5cm, 3cm at the most. Mine has been restricted since Jan this year. I have suffered TMJD for a nuber of years fortunately without too much pain but plenty of clicking and discomfort. It was in Jan this year that my click changed and that's when my bite and limited mouth opening also changed. am currently still waiting to have an MRI doen to see what the damage is to my discs, whether it's just the one side or both sides that are damaged.

I will eventually starts the same treatment plan as jmitchell, starting with a lower repositional splint. I have worn an upper mouthguard at night but to be honest only for 2 nights because it actually made my jaw shift even more over to my right side so I just wasn't comfortable or convinced in the slightest that it was going to help me at all.

I'm just a lay person who has experience of the torments of TMJD like others here on the forum and I can only share advice that i have found has helped or made sense to me and I think from reading your post that it will be the discs or one the discs that are damaged. I would seek out a specialist dentist in TMJD and probably go for another MRI to double check the discs.

Hope that you find the help you need x
