Why implants fail — and the three habits that prevent most of it
Implant survival is above 95 per cent at ten years. The cases that fall outside that number usually share three causes, and two of them are within the patient’s control.

Cause one: placement, decided before surgery
An implant placed where the bone happened to be, rather than where the crown needed to sit, is loaded off-axis for its entire life. This is a planning failure and it is fixed in software, not in the mouth. Ask to see the plan on the CT before surgery.
Cause two: peri-implantitis
The gum around an implant inflames like the gum around a tooth, but the tissue attachment is weaker and bone loss progresses faster. It is usually painless until it is advanced. Daily interdental cleaning and a professional review every six months is the entire prevention protocol.
Cause three: smoking
Smoking measurably reduces implant survival by impairing blood supply during the healing phase. The effect is largest in the first three months. Stopping for two weeks before and eight weeks after surgery captures most of the benefit even if you resume afterwards.
Three habits that cover most of it
- Interdental brushes daily, sized correctly. Floss alone does not reach around an implant abutment.
- A professional maintenance appointment every six months, where the tissue is probed and measured rather than glanced at.
- A night guard if you grind. Implants have no periodontal ligament and therefore no proprioception — you cannot feel that you are overloading them.
What to watch for
Bleeding when you clean around an implant is not normal and is the earliest sign worth acting on. So is a metallic taste, a change in how the crown feels under pressure, or any looseness at all. None of these should be given time.
