Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you are suffering from Peri-Implantitis that is infection and inflammation around the implants leading to destruction to soft tissues as well as bone.. Therefore recession of gums and bone destruction is evident.. At times proper debridement of the damaged tissues and maintaining proper hygiene by doing antiseptic mouthwash gargles and proper brushing can help.. In case if there is excess loss of bone then crowns aa well as Implant needs removal and bone grafts might be required.. Consult an expert Implantologist and get proper evaluation and x rays done and after a second clinical examination only you should proceed with treatment.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
