Half of my face is not reacting well. When I talk or laugh, my left face is reacting and my right face doesn't. My right side feels like dead but I can feel a touch on that side. It doesn't work well. My eye on that side is constantly watering.

I went to the hospital four days ago but they couldn't find out what is wrong. I also went to the dentist but she said there is no cavity so i should come back on Monday for cleaning of my teeth and then we will recheck. I was seriously bleeding yesterday when I was brushing my teeth. I don't feel any pain which is weird. Do you may be know what is wrong.
