Had Upper dental implant in three years ago and they give me bad breath - advice?

Bad breath can be a sign of peri-implant disease, which can jeopardize the survival of your implant. The implant, unlike a natural tooth, does not have a periodontal ligament for protection, so it is more prone to bacteria adhering to the surface generating bone loss and, therefore, loss of implant retention. For this reason a correct hygiene technique is essential, flossing and the use of waterpick can help to better clean the area. I would also recommend a visit to the dentist for a review with radiography and clinical examination of the current state of the implant.
