I had part

I had part of one of my back tooth come away, went to the dentist who fixed this, but it put pressure on my front teeth, so I went back and he relieved the pressure. He said that because the back filling was around the outside of the tooth as well, it had taken up more space, so he filed in between a couple of other teeth. The pressure went away but then I noticed that my top front teeth has started to move slightly, by this I mean that they sort of clicked together while eating and stuff. I went back, he had a look and said it was not a problem, he filed the back tooth down some more to get more of a gap back and said that the other teeth were moving slightly, annoying as it was, it was ok because they would just right themselves, I had to give it time. It was because of the bunching from the back tooth being a bit larger and my bite had changed causing this problem. I wanted to know how long this could take because some days they don’t move at all and others they click together a little. My dentist had a look and said that the teeth have moved slightly but once they are comfortable in their new place they will settle down and not move. He also said that to me it feels like they are moving miles, but in fact it is probably only less than a hair. He pushed on the teeth to see if they had become loose but said they had not and this was normal for them to move slightly while getting used to a new bite. I am sorry if I sound a little confused, I was just wondering how long it would take to stop moving, cos as I said some days they don’t move at all and others they do.
