Guides · Risks
Most implants integrate and last. A small number do not, and the dental implant risks are well understood: infection, smoking, uncontrolled diabetes, loading too early, and inflammation of the gum around the post years later. Marketing pages skip this. It belongs here.
Two phases
Early failure means the post never integrates: the bone does not bond to it in the first months. Infection at the site, smoking, poor bone quality or loading the post before it was ready are the usual causes. It shows up as a post that stays mobile, and it is dealt with by removing it, letting the site heal and reassessing.
Late failure is different and usually slower. Inflammation in the gum around the post spreads to the bone, which then recedes, exactly as gum disease does around natural teeth. It is largely preventable by the routine on Caring For Implants, and it is what makes recall appointments matter, as covered on Living With Implants.
Both dental implant risks are far less likely in patients who suit the treatment, which is what Implant Candidacy assesses.
The main risks
The largest factor you control. Reduces blood supply to healing tissue and raises both early and late failure substantially.
Impairs healing. Well controlled diabetes is much less of a concern, which is why recent readings matter more than the diagnosis.
The same bacteria attack bone around a post. Treating it first is not a delay, it is what makes the implant worth placing.
Mechanical overload rather than infection. Usually managed with a night guard rather than by avoiding treatment.
Rarer problems
In the lower jaw the nerve running through the bone can be irritated or damaged, causing numbness in the lip or chin that is usually temporary and occasionally not. In the upper back jaw a post can enter the sinus. Both are uncommon and both are what careful planning is for, which is why CBCT Imaging maps those structures before surgery and Guided Implant Surgery holds the position during it.
Mechanical implant risks are more common than surgical ones and much less serious: a screw loosening, a crown chipping, an attachment wearing. These are fixed rather than being failures. Timelines and what wears when are on Implant Lifespan.

Victoria patients
The page on what can go wrong was the one that made me trust everything else on the site.
Given the real numbers rather than a sales pitch, then left to decide. That is why I went ahead.
Rang when pain was climbing on day four. Seen the same day and it never became a problem.
Told me smoking would move the odds and by roughly how much. No lecture, just the number.

When you are ready
General risk is one thing, your risk is another. Smoking, medical history, bone quality and grinding all shift the odds. Ask at the consultation where you personally sit, and expect a straight answer.
