Missing Teeth Treatment Planner

No, and assuming so is the most common reason people overestimate the cost. Two implants routinely carry a three-unit bridge, and an entire arch of twelve to fourteen teeth is carried by four to six. One implant per tooth is normal only for isolated single gaps. This is also why the pattern of your missing teeth matters more than the count: four gaps in a row cost far less to close than four gaps spread around the mouth.

Three things, and all of them make later treatment harder. The bone that held the root is no longer loaded and slowly shrinks, which is the usual reason a graft becomes necessary. The teeth beside the gap drift into it and the opposing tooth grows down towards it, so the bite has to be corrected before anything can be placed. And the longer both go on, the more likely the final result needs orthodontic work first. None of it makes treatment impossible; it makes it longer and more expensive.

Not until it is treated and stable, but that is a delay rather than a refusal. Implants sit in the same bone that periodontal disease destroys, and placing one in an actively infected mouth is the clearest predictor of failure there is. A reputable clinic will treat the gums first, wait, re-measure, and only then plan implants. If a clinic offers to place implants at the same appointment as extractions in a mouth with untreated gum disease, treat that as a warning about the clinic rather than good news about your case.
