Irregular Smile After Facial Fracture Surgery?

First of all, Please forgive for my English. I'm a non-native speaker, thus my writing is not very good. I just had a facial reconstructive surgery on my left face because my cheek on that side was pop in after I fell of on ice. The incision was made inside the mouth to prevent from getting scar. However, what I'm feeling is that my smile is different. I wonder that my smile will back to normal in next few weeks/months or it will change permanently. Thanks very much for any help
