Sir it's advisable that you don't go for implants if you are having a gum disease. If the disease continues to progress and you get implants in that state then either the implants won't thrive or else you could develop another form of gum disease. We could be wrong however, but before you arrive at a decision regarding implants, please consult any of the following doctors for a second opinion - a.) Periodontists in Kolkata, b.) Implantologists in Kolkata.
