My Aunt is 86. In the past years she took a fall, and ended up having hospitalization with surgery, extensive rehab im-patient and out. During this time she lost a bunch of weight. Took her to the dentist because her dentures were bothering her. Dentist said, it doesn't fit right because she lost weight. Once she puts the weight back on, the denture will be fine. I'm not a dentist., but don't gums shrink, just like the rest of the body when you get older? Do you think I should take her to a Prosthodontist (dental specialist) for a second opinion?
I would definitely say to take her to an oral surgeon, because they have more experience with loss of bone and ill fitting dentures than a general dentist would have.
