Hi...
We need to know do you have mobility in those lower teeth or not although the x-rays show a lot of bone resorption so it must be mobile.
You can consult a periodontist and they might advice you to go for a flap surgery along with bone grafts but the prognosis might/might not be good.
Since you are just 26 the healing can be good but physical as well as radiological examination will help in getting to a good treatment plan.
Next Steps
Consult a dentist online/offline soon
