Hiya, i remember my grandad use to do that alot, he couldnt control it and im sure it was a nervous habit.
If it becomes problematic maybe she should pop along to the doc just to make sure all is ok.
What you are describing sounds benign to me; i.e. perhaps her mouth is dry and that is her way of stimulating saliva.
Why not, in a kind way, ask her if she notices she is doing it and if so, why. After all, she is your wife.
Good luck. Hope you get a simplistic answer to alleviate your concern.
has she been under any stress lately,it could be a nervous disorder
Never hurt Michael Jordan any.
Hello, is your wife nervous? Does she seem to be pre-occupied? I think I would probably see a doctor and at least let them know what is going on. It could be just "nerves" then agian, it could be something else.
