Implants do not develop tooth decay, but the tissues around them can become inflamed. Bleeding during cleaning, tenderness, discharge, or a change in the gum line deserves attention. Peri-implant mucositis affects the surrounding soft tissue; peri-implantitis involves inflammation together with progressive loss of supporting bone. Distinguishing those conditions requires more than looking at the colour of the gums.
An assessment brings together the implant history, gentle clinical measurements, the restoration, and appropriate X-rays. Earlier records are especially helpful because implant designs and initial bone levels vary. The aim is to identify what has changed, whether the restoration can be cleaned effectively, and which treatment or specialist input is appropriate. It is not an automatic recommendation to remove the implant, replace the crown, or prescribe an antibiotic.
