Can Your Front Tooth Just Fall out of Your Mouth? (photo)

From the attached pictures you do not need to worry about your front teeth "falling out."  Though you may have had some gum recession, the teeth are anchored to your upper jaw (maxilla).  To put your mind at ease I would set up an appointment for a complete exam and X-rays with a local dentist.  Your dentist can evaluate the X-rays and show you that there is sufficient bone holding your teeth in place.  Hope this helps. 

Hi in Phoenix, Arizona!  Do not stress over this!  Your upper teeth are embedded in the maxilla, or upper jaw bone and are covered by gums. You are experiencing gum recession, which could be due to the fact that you use a hard bristle tooth brush and brush to hard or the wrong way. Also you could have the beginning of periodontal disease. I would not worry about your front tooth falling out anytime soon!  You should see a dentist to find out what is causing gum recession. Take good care of those teeth!

I wouldn't worry about your teeth falling out in the short term.  There is still plenty of bone (from what I can see) that I dont think that they will come out with your next bite of a sandwich.  However, you may have gum recession and general bone loss which is associated with periodontal disease.  I'd see your dentist to have your gum health evaluated and see if further action (deep scalings, perio surgery, etc) is needed.
