Bone Loss around Dental Implant: Options?

I am a patient. The lower left molar was implanted about 6 years ago. It looks I progressively have lost bone around the implant. Originally, I went through 1 unsuccessful implant and 2 bone grafts before this one implant was placed. The gum around the tooth is also problematic. I have food stuck there and minor inflammation sometimes. I also have minor bleeding sometimes. The X-rays are 1.5 years apart. What are my options here? Clean and regraft?
