Yes, the dental implants can get infected!!
Bacteria can collect on implant surfaces, and this can lead to peri-implant mucositis and/or peri-implantitis. Peri-implant mucositis is a reversible inflammatory reaction within the soft tissues that surround a dental implant, but with no bone loss. Peri-implantitis is an inflammatory condition around dental implants often associated with the loss of surrounding bone. Implants can be considered to be ailing or failing. Ailing implants refer to those that exhibit bone loss with pocketing. This pocketing is historically stable upon assessment at maintenance appointments and does not progress. Failing implants refer to those that exhibit bone loss with unstable pocketing. This condition is associated with continuing changes in bone architecture, purulence, and bleeding on probing.
