What is trismus?

 I have trismus now what?

Trismus is the inflammation of muscles of mastication causing restricted mouth movement. There is pain in the muscles and joints, which results in pain with any movement.  It is a frequent result to surgical removal of mandibular third molars (lower wisdom teeth). Trismus usually resolves on its own in 10–14 days, during which time eating and oral hygiene may be more difficult.  It does occur do to injection of local anesthetics and is more likely from the physical trauma of the injection itself on the medial pterygoid muscle.  By rarely I mean I see it at my office between 0-2 times a year, less than 1 average.

 Muscle trismus Treatment

To prevent trismus progression to a chronic state, treat early with heat, analgesics, muscle relaxants, and exercises. The application of heat (e.g. heat bag extraorally, and warm salt water intraorally) will help reduce the severity and duration of the condition.  Additionally, control of symptoms with pain medications (NSAIDs) and muscle relaxants may be used.  Passive range of motion stretching needs to be done 10 times per day.  Passive range of motion refers to the moving of body parts without activating muscles to perform the movement.  In this case that means you use your hands to pull your lower jaw open as far as you can and holding it for 30 seconds.

Some very fake acting of trismus suffering.

Bottom line for trismus treatment

1.  Take 800mg ibuprofen three times a day until symptoms are gone, up to 10 days.
2.  Use heat 15-20 minutes at a time 4-10 times a day
3.  Take Flexeril (cyclobenzaprine) 10mg at night.  Can take 10mg in morning too but has side effects!
4.  Physical Therapy: open and close as well as side to side movements 5 minutes every 3 to 4 hours. Chewing gum for 5 minutes every 4 hours will take care of this.  Also use passive range stretch and hold as wide as can for 30 seconds 10 times a day.
5.  If the pain is persistent and continues for more than 10 days I want a phone call.  That could be a sign of an infection setting in.
flexeril main side effects are drowsiness, dizziness and lightheadedness do not take with alcohol or if have taken MAO inhibitors within 14 days
