An exerciser device of the present invention is disposed in the mouth for exercising in the mouth through the use of tension. The exerciser device of the present invention includes a guard strip for passing over the front and sides of the upper and lower teeth. A grip piece extending form an inside of the guard strip is used for gripping and holding the guard strip in position during use. Preferably, the guard strip comprises a pair of tabs separated from each other such that the upper and lower teeth are separated from each other to avoid discomfort caused by the upper and lower teeth being clenched. An elastic member anchored in a first corner of the mouth passes along a first side of the teeth towards the back of the mouth, passes through an opening in a distal end of the mouth guard, crosses the back of the mouth, and passes through another opening in the distal end of the guard strip on the other side of the mouth and then extends from the rear of the mouth toward the front of the mouth for being anchored in the other corner of the mouth. Accordingly, when the shape of the mouth is moved between and "O" shape and a smile shape, the elastic member changes the degree of tension, thereby exercising the muscles in the face, chin and neck.
