Dental implants are not a cure all. They are titanium (non-magnetic, don’t set off metal detectors and MRI scans are OK) and don’t decay, never need root canals, and are hard to break, unlike teeth. The only thing they are subject to that affects teeth is periodontal disease. If you don’t keep them clean, you can have failure from gum and bone loss. They are just as easy to maintain as teeth. In may cases, you get a do-over or second chance at fixed teeth. However, like the old adage says “You only have to brush and floss the teeth (or implants) you want to keep”.
The x-rays show the unfortunate demise of an implant. Additional implants are functioning well. Regular followups by your general dentist are necessary. Treatment can be done when problems are detected early. This implant was beyond hope, with complete loss of bone surrounding it. After the bone heals in the area, another implant could be placed in a few months.
