Hi MamaC
Yes, a little bit for me post 2nd tonsillectomy/rads etc.
Here's some exercises given to me by my SLP at Johns Hopkins.
Ideally to be performed 1-3X daily
Jaw Opening
Open your jaw as wide as you can until you feel stretching, but no pain. Hold this position for 5 seconds, Relax. Repeat 10X
Side-to-Side Movement
Move your jaw to the right as far as you can until it pulls but doesn not hurt. Hold it there for 5 seconds. Relax. Repeat 10X
Same exercise to the left.
Increasing Circular Jaw Movement
Pretend to chew (as though you were chewing gum) in small circles with mouth closed, rotating to the right and then to the left. Alternate right and left for a total of 20 times.
Mouth Opening Check
Monitor mouth/jaw opening. Insert three fingers (between thumb and pinky) into mouth. You should be able to do this easily.
There are some others but these are pretty standard fare. Consulting with a Speech/Language Pathologist would be prudent should these difficulties with your mouth persist.
