You are correct, periodontal disease is an aggressive disease. The first step would be making certain that you and your clinician have teamed together to achieve optimal results, it sounds like you're in a stable state, but always keep a close eye on it. There are different periodontal mouth rinses that can be used, and more frequent deep cleanings that may be done to reduce your risk for bone loss. Since the bone cannot be brought back, and implant wouldn't necessarily change the spaces, and the other concern is that implants can still get periodontal disease. One option you could do is to crown the teeth, it would afford you the ability to eat out comfortably by closing the spaces, if done correctly. Since implants are based on bone, the implants would not offer any better result that your natural teeth. Another option for you might be orthodontics with interproximal reduction, but that can be limited. Check with an orthodontist or your general dentist to see which options are best for your situation. Smiles, Dr. Shelton
