In almost all the cases of mobile teeth, extraction is the only solution. The Other few minor percentage of cases where extraction can be avoided need to be evaluated first by a proper clinical examination and some X-rays, if required. Please try to visit dentist as soon as possible so that the right treatment options can be delineated for you. Regards.

Please visit a periodontist nearby your area. They are specialized for gum and bone treatment which is required in your case. You can search them in practo itself. He would be able to tell you what exact treatment is required. Hope this helps.
