A denture reline is a procedure that improves the fit of a denture by reshaping the inner surface that rests against the gums. Over time, the gums and jawbone naturally change shape, which can cause dentures to become loose or uncomfortable. A reline adds new material to the denture base so it fits the mouth more securely. This helps improve stability, comfort, and chewing ability. It can also prevent sore spots and irritation caused by poorly fitting dentures. Regular relines help extend the life of dentures and ensure they continue to function properly, allowing patients to speak, eat, and smile with greater confidence.
