If you have to have a tooth extracted, the optimal time for implantation is often immediately in the same session as the extraction! This means that you only receive a local anaesthetic, save yourself a second appointment months later, and do not leave the dental practice with a gap between your teeth, but with a temporary denture over the implant. The finished denture can be inserted just 2-4 months later. From a medical point of view, there is a lot to be said for so-called immediate implantation. It is almost the only way to ensure that both hard and soft tissue are kept in place as they were at the time of extraction. The longer one waits after an extraction until the implant is inserted, the more the bone degrades.
