I have had my veneers for several months, but I was never good about keeping my night guard in over night (it always fell out), plus, when it stayed in my back teeth and jaw were both sore. My night guard fell out and I can't find it. By the way, I got veneers to fill a space in my teeth, if that helps anything. So... what does this mean for my veneers. Will the veneers begin to space out like my teeth were before? Will they break? Please help.
