Since an implant cannot attach as easily to the gums as natural teeth, the risk of inflammation and in the end peri-implantitis, is much higher. The gum stays loose around the implant and therefore harmful bacteria can nest more easily in the gum. This can cause not only cause inflammation but also bone loss. Of all implant patients, more than 40% are affected by inflammations around the implant, known as peri-implantitis.
