My dental implant was placed 3 months ago and an x-ray has confirmed it moving, what do I do?

the dentist filled the back of the crown so it was not catching when I chew the bottom row of teeth and told me to come back in a month to have the implant removed and done again my question is if i leave it loose as it is going looser by the day will this deteriorate the gum or can i get any problems with gum loss i was under the impression that it should be done A.S.A.P SO it does not do any damage im so worried the tooth is a t the front of my mouth i do have receding gums please help thank you
