Do you have loose or floppy dentures that do not stay in place? This can cause difficulty in eating and can cause painful rubbing to gums and tissues. In addition, it can cause damage to your tissues that may require surgery to correct. The bone under your gum tissue is what really supports a denture. There is a natural reduction of the supporting bone over the years but loose fitting dentures may hasten the process. Implants inserted into the bone tend to stop this from happening. Due to shrinkage of the gums, a reline or rebase may be recommended to help your dentures fit better.
