The staccato sound when opening the mouth may be caused by TMJ strain, TMJ disorder syndrome, joint displacement and so on.
1. Temporomandibular joint strain: due to long-term incorrect biting habit or excessive mental stress, it can cause temporomandibular joint strain, which leads to thumping sound when the patient’s mouth opens, accompanied by symptoms such as limited mouth opening and temporomandibular joint pain.
2. Temporomandibular joint disorder syndrome: If it is caused by occlusal factors, trauma, muscle group dysfunction, excessive joint load, inflammation and immune factors, it may also lead to thumping sound when the patient’s mouth is opened, accompanied by symptoms such as abnormal jaw movement.
3. Joint displacement: if the patient’s mouth opens with a thumping sound, it may be caused by the movement of the joints in the process of movement, which is generally categorized into reversible and irreversible two cases.
There are many other reasons for the staccato sound of mouth opening, and it is recommended that patients actively seek medical attention to clarify the cause of the relevant treatment.
