Acute TMJ Closed Lock
For Patients
Effective Solutions for Acute TMJ Closed Lock
An acute TMJ closed lock occurs when the jaw has limited opening from the closed position. This can occur after the jaw joint has been making clicking and popping sounds for quite a while. A closed lock can be caused by muscle tightness and/or the disc in the temporomandibular joint being in the way of the jaw opening. Pain can occur when you try to open your mouth from this closed-lock position.
Sometimes there is a bit of warning before the mouth gets stuck in the closed position. This warning could be episodes where the jaw locks and then unlocks. In some situations, however, the jaw gets stuck in the closed position without any warning.
If your jaw gets stuck in the closed position it is important to visit a properly trained dentist within a week of the first occurrence. This will help you to recapture the TMJ disc and return to normal jaw function. As time goes by, however, the TMJ disc will deform and will become stuck, or it will adhere to the new closed-lock position. When this happens, the situation will deteriorate into a chronic TMJ closed lock where it is much more difficult to recapture the TMJ disc.

Jill Krstajic2024-10-31Trustindex verifies that the original source of the review is Google. It is not an understatement to say that Dr Goodfellow and his staff have greatly improved the quality of my life! My TMJ pain was unbearable and as a Dental Hygienist I was actually skeptical that the treatment would work, it did and I am grateful! I would gladly recommend Dr Goodfellow for anyone suffering TMJ and Sleep Issues. Lanndis De Lallo2024-09-30Trustindex verifies that the original source of the review is Google. This device changed my life. I have had TMJ for as long as I can remember with a long history of orthodontic work from childhood. For the first time as an adult, I can control my jaw pain, clicking, locking and tension headaches with the night time appliance, which I wear every night - I can feel the difference even going one night without it. The daytime appliance also makes a big difference and now I can wear it periodically. Dr. Goodfellow, Cathie, Tina and the entire team are delightful, helpful and I can't thank them enough for helping me implement this life changing, non-surgical solution to my TMJ!

That pain is now virtually gone. I am so grateful and I highly recommend Dr. Goodfellow! Julia Leclerc2024-07-23Trustindex verifies that the original source of the review is Google. I suffered from severe jaw pain and eventually jaw locking. Dr. Goodfellow not only was able to diagnose the issue, he was able to completely redirect my jaw and sleeping patterns with the mouth guard that I now wear to sleep every night. I don’t even get headaches anymore! The difference has been incredible and I am forever grateful. Highly recommend Dr. Goodfellow and his staff.

I've had a click in my jaw for over 30 years and over the past year it was constant pain and difficulty chewing. Dr. Goodfellow and his staff provided me with a non-invasive appliance one for the day and one for night and within 6 months I was pain and click free. It's as if I have brand new jaw with no issues whatsoever. Without a doubt, the best medical treatment I've ever received. I would give six stars if it was available.
