Sudden Bone Loss Around One Tooth over 1 Year Time?

As was said by the others, systemic bone loss generally effects all teeth, or a area/grouping of teeth.  Have you had a change to these teeth recently, fillings, crowns, etc...  Are you wearing an appliance that has changed, or is new?  Occlusion is often the answer when it comes to targeted bone loss or looseness.  Changes in the mouth often are the cause of this.  I would suggest seeing someone that is experienced in dealing with occlusion/equillibration.  This may not save your teeth that have become loose, it may help prevent loss of others in the future.

Rapid bone loss on one or two teeth is probably not from a systemic problem. All you teeth would all be affected. However, if you have concerns, of course, see your physician. Just one tooth is most likely from a fracture and the fact that you have another loose tooth without gum disease would point to occlusion being the problem. If you are missing several teeth you probably need to look at restoring your mouth in order to have a balance supportive bite.
