My gums have disappeared because of using dentures for more than 40 years. Could implants be done if there are no gums left?

Wearing dentures for a long time cause bone resorption due to pressure of dentures exerted on the gums and bones! It is best you see an expert dentist, for a complete evaluation, specially the bone level! If bone level is not sufficient, there is possibilities to add bone so you can get implant supported denture!

Hi:Unfortunately without photo and X-ray it is difficult to give you accurate advice.  Please post photo and X-ray of the affected area.

Hi Ivan,Bone will resorb from wearing dentures for a long time and that can affect your chances of being a dental implant candidate. You need to go in a see an experienced dental implant specialist and have them determine the health and hardiness of your bone. Depending on condition, there are ways to build up bone to get you to an acceptable implant level.Good luck!
