1) Rubber Bit
I had several teeth come loose recently.  I found that biting down on rubber actually helps to tighten the teeth.  I will bite down on the rubber using both sides of my mouth, and I also use the front teeth as well.  I found that the front teeth on the bottom were coming loose, and this was likely due to the fact that they did not get much stimulation and use because of my bit.  Oddly enough, I was able to obtain the rubber from my turkey baster.  I cut the strip or rubber off of it and then folded it over so that it was three times folded over.  After following this regimen for several weeks, I went to my dentist and she was shocked by how well my teeth were doing.  I went ahead and told her what I had done to tighten my teeth and she was amazed and told me to continue doing it! This is a great and effective home remedy for loose teeth.
