I have done root canal treatment of teeth before 3 days but my teeth was jerk before done root canal treatment.Was it possible it will be well and I can't loose a teeth?

I'm a little unsure of the question...

Having a root canal can mean several visits to your dentist. If you mean that after the treatment was started your tooth sustained trauma of some kind, it really depends on the current status of the tooth, if it is loose or wobbly, the chances are much higher that it would have to be removed. Your dentist can have x-rays taken and judge best on the situation. Dentists' last resort is to pull teeth, and even if this has to be done there are always means of replacing a tooth, implants, prosthetics etc.
