This is the usual end result of untreated severe gum/periodontal disease, dentures or no teeth at all. I have been treating people with severe gum disease in Palm Harbor, Tampa Florida for more than 24 years. In all these years of practicing dentistry in Palm Harbor some patients with periodontal disease have been able to stabilize and maintain their teeth and others have either gradually lost them or chosen to have them removed.
My observation is that MOST people can get used to upper dentures, while MOST people do not ever get used to lower dentures (for them dental implants can be a viable and cost effective solution.)
