I Have Severe Periodontal Disease, What is the Best Option ?

First, don't waste time and mess around, see a gum specialist....a periodontist.  It sounds like you have a pretty bad case of periodontitis.  Your new periodontist will best treat your advanced infection and in many cases, if necessary, can place the implants where indicated.  Most periodontists work in combination and as a team with either your current dentist, or a restorative dentist who will make appropriate restorations for you.

Hello JJov,You should definitely stop throwing good money after bad! If you are already losing bone and receding gums then the infection is spreading quickly and will turn into more tooth-loss. Are you seeing a periodontist?There are many different dentures that you can wear. From traditional removable dentures to fixed dentures with implants. The later help you to stop bone loss. There are a lot of affordable options out there even outside the US or Canada.The comfort would depend on how well fitted they are and the materials and techniques being used. There's no reason to stop eating what you love or changing your lifestyle as long as you choose the right dentures!
