Your xray shows mild to moderate bone loss, pointing towards gum infection entering the bone and eating away your bone. However, good news is that, all these can be normalized and the infecting stopped.
We can't see gum recession in an xray, but the severe sensitivity can be due to few decayed teeth and abrasion of teeth as seen on the xray.
All these can be set right once you visit a dentist, especially a Periodontist.
You will need deep cleaning, fillings and desensitizing toothpaste. If your gum infection doesn't settle with these treatments, you may need further gum treatment and can be controlled non-surgically with lasers at this stage
