Why did my teeth shift after getting root canals?

I had three root canlled teeth on the front bottom teeth. I had them removed but this picture was prior to them being taken out. In the x ray i had had them for five years. Before getting root canals my teeth were vertically completely straight.  Had them in for five years and i find it very strange and suspicious that the two bottom left side canaled teeth had completely been pushed and shifted to the left side. They also seemed to had risen a few milimeters. All my dentist and oral surgeon "see" was some Bone granulation when i had cavitation treatment to clean out the socket. But they definatly and totally missed something.  mentioned this in another post on the cavitation forum that when i removed them for about two days i felt healthy and normal. I suffer with extreme and chronic fatigue dry mouth, leaky gut, etc. I know there is an issue in the jaw where the root canal teeth were. I had a CT scan done for the first time on my jaw today. Hopefully there will be some kind of findings. If not I would go on to get an MRI. Any suggestions on scans that would be effective in finding bone deformities/infections.
