My 95 year old mother has had dentures for 40 years (full) She has asked her dentist to re-line them because her bottom rights rub against her gum and it hurts so bad she can't eat, is losing weight and is very depressed. I have never seen her depressed. The dentist told her to get implants and he can't reline the dentures. Are there other options. This is sad. Thank you so much.
