hi michelle.
you would definatly have stiifness in your jaw as well and it would be slower to move.
when my jaw is really bad it effects the articulation of my speech.
eating can be a nightmare,i lost a lot of wieght last year because i was unable to chew.
i have never had tooth or gum pain but my facial muscles can be very painfull.
once my cheeks were so spastic and hard it looked like i had golf balls in my mouth
i do get dystonia like spasms in my right jaw muscles,these physically distort the right side of my lower face and mouth. i can not turn my neck/head round to right as it can set them off.
1+ jaw reflex would not cause jaw problems or spasticity. also it would not suddenly become spastic.
there could be many other reasons for your facial pain like grinding your teeth or even stress.
unless it causes complications with talking and eating i am sure it will be ok
