Can I get a bone graft without getting implants?

WorriedOne, you can certainly get bone or gum grafts independent of dental implants. From what you describe, it sounds like you'd be best suited to see a periodontist, who is a specialist of the gums and bone that support our teeth. Periodontists are trained in grafting of both bone and gums, and much of what they do is based around saving a protecting teeth. 
While you're there, you should also ask about the best ways to maintain your periodontal health going forward. Although there is no "getting better" from periodontal disease, we don't look at it as the point of no return that we used to. There are treatment modalities: lasers, PerioProtect Trays, localized delivery of antibiotics like Vibromycin, and bone defect repair materials (Emdogain) that can improve areas that are tough to graft. 
Hope that helps!

Hi, Worried One. It sounds like you do have periodontal disease if you have bone loss on your front teeth. I definitely recommend seeing a periodontist as soon as you can. Good luck.

Bone graft is indicated for various conditions. Common conditions requiring bone graft are enhancement of bone around teeth with loss of attachment (and bone), extraction site bone augmentation, or grafting a site withe defect planned for implant. It sounds from your description that you have periodontitis. If this is the case, a periodontist can advise on necessity of bone grafting. If bone grafting for other reasons, you can then see an oral surgeon who may be a better fit.
