Your dentures will become loose over time. This is completely normal and expected. It’s one of the big drawbacks of typical dentures and why we recommend looking at Implants as an option. Natural tooth roots are embedded in the jawbone, providing a stable foundation for your teeth. When teeth are lost, the bone that previously supported them begins to deteriorate, or resorb. This causes the tissue to shrink accordingly and makes your denture loose.
To maintain your existing denture, your denturist would suggest a reline. A reline is the process of adding a new base of material to the tissue side of a denture so it can fit properly. This would require taking an impression of your existing denture. A reline will improve the fit of your denture but it will not change the appearance.
