Aren't dentures something you use for life once they are made? Is there a replacement cycle?

Dentures are not for life; their lifespan is generally considered 5 to 7 years. The jawbone resorbs over the years so its shape changes, and the chewing surfaces of the denture wear down. The National Health Insurance also covers a new denture once every 7 years for patients aged 65 and older (with a 30% co-payment), and in the meantime changes in the gums are compensated for with repairs such as relining, which fills in the inner surface. Wearing a loose denture for years without repair speeds up bone resorption and easily leads to pain and inflammation. However, even before 7 years, a fracture or severe looseness needs to be assessed and repaired, so please come in.
