You may often have experienced you mouth is unable to open properly when your dentist asks you to open your mouth wide. Or even when you want to take a large bite of your burger you once did. Reduced mouth opening is when you can’t open your mouth completely. Normal mouth opening is around 40-50 millimeters. A trismus or lockjaw is when the mouth opening is just 35 millimeters or less and is associated with pain. The TMJ or the jaw joint is responsible for the opening and closing of your mouth. Any kind of injury to this joint could limit your jaw opening.  Factors like external injury, displaced disc due to excessive movements, muscle injury, night grinding or clenching  of teeth or even arthritis can cause damage to the TMJ. So do not ignore the clicking sounds coming from your jaw, as it could mean a TMJ disorder. Other possible reasons could be wisdom tooth problems, space infections or even precancerous lesions. Trismus has a number of potential causes which are single and ranges from simple and non- progressive to those that are complex and potentially life threatening. Reduced mouth opening when diagnosed early could save you from further consequences. This condition is definitely serious and needs attention from your dentist.
