hi
hope you dont mind me popping in here as this is my first time posting on your forum
my son has Tourette Syndrome and my knowledge of autism is limited to what I have learned in my TS research and from some friends whose children are autistic
One of my son's most intense Tourette tics used to be tooth grinding and also snapping his teeth together really hard
Our physician recommended pantothenic acid (vitamin B5 ) and the improvement for my son was truly remarkable. I have since learned that B5 is generally recommended for bruxism, as is Royal Jelly, which is very rich in B vits, especially B5
anyways...dont know if that is at all relevant to the tooth stuff that you are discussing so forgive me if it isnt

Just thought I would mention it in case it could be helpful
