Yes, plaque can grow on implants just like it can on natural teeth. Plaque is a sticky film of bacteria that forms on teeth and gums, and if not removed through proper oral hygiene practices, can lead to gum disease and other oral health issues.
Similarly, plaque can accumulate on the surface of dental implants, leading to inflammation and potential implant failure. This condition is known as peri-implantitis and can cause bone loss around the implant.
