粪肠球菌出现在许多牙根感染中，不能通过根管治疗消除。它可以驻留在牙根管和周围的骨骼中。这个物种可能在被感染的牙齿拔除后在骨骼中生长，并在愈合的位置放置后在牙科植入物上定居。定植可能会导致固定物丢失或边缘骨质丢失。这些定植通常是多细菌的，致病特性可以通过质粒分享。然而，粪肠球菌在一些培养技术中是检测不到的，因此可能会被遗漏。在这些感染中，它通常不是优势物种。尽管如此，粪肠球菌可能是种植体骨丢失或种植体周围炎的“基石”。也就是说，粪肠球菌可能是多种感染的任何特定种植体周围炎的致病决定因素。
Enterococcus faecalis appears in many tooth root infections and is not eliminated by root canal therapy. It can reside in tooth root canals and the surrounding bone. This species may vegetate in bone after extraction of an infected tooth and colonize a dental implant after placement in the healed site. A colonization may cause fixture loss or marginal bone loss. These colonizations are generally multibacterial and pathogenic properties can be shared via plasmids. However, E faecalis is not detectable with some culture techniques and thus can be missed. It is usually not a dominant species in these infections. Nonetheless, E faecalis may be a "keystone" player in dental implant bone loss or peri-implantitis. That is, E faecalis may be the pathogenic determinant for any particular peri-implantitis infection of a multiple-species infection.
