Can a dental implant get infected after 4 years?

Yes, you can , even once the implant its integrated and strong. The hygiene around the abutment and crown , needs to be perfect, if not remember that the gap between the implant and the gum, has no ligaments ,so this can be an area of food or bacteria storage, causing all this you are saying. If you go to your specialist , there is a chance of implant recovery, with different surgical procedures. Hope this helps!

The red gums and white draining from above the implant sound like an infection.  Schedule a visit with your surgeon as soon as possible.  Implants can get an infection just like teeth.  We also will try ozone gas or a LANAP (laser gum surgery) to save infected implants.

A dental implant can get a gum infection in the same manner that a tooth can develop a gum infection. If a space was present at the time that the implant was placed, or a space developed since the time that the implant was placed, then bacteria can accumulate in that area, which is known as a periodontal pocket, which will result in the production of pus and can ultimately destroy the bone around the implant. Depending upon the extent of the bone loss around the implant, it may or may not be savable.It is best to have it looked at as soon as possible to determine if it can be treated concede.I hope this information is helpful,Dr. Champagne
