Dentures are designed to replace missing teeth and help restore oral function and aesthetics for individuals who have lost some or all of their natural teeth. When dentures stop fitting properly, it is essential to see a dentist. They can evaluate the fit and condition of the dentures and make adjustments or create new dentures as needed to ensure optimal comfort, function, and aesthetics. Regular dental checkups and adjustments are crucial to maintaining good oral health and the proper fit of dentures. Here are some reasons why dentures stop fitting  properly:

• Bone Resorption: When teeth are lost, the underlying jawbone that once supported those teeth can start to resorb or shrink over time. This bone resorption can cause changes in the shape and size of the jaw, leading to a poor fit of the dentures. 
• Natural Aging Process: As we age, our bodies undergo various changes, including changes in the structure of the oral cavity. The tissues in the mouth may lose their elasticity and volume, leading to a change in the fit of the dentures. 
• Denture Material Wear: Dentures are made of materials that can wear down over time, affecting their fit and function. As the materials degrade, the dentures may become loose or ill-fitting. 
• Poor Denture Maintenance: Proper care and maintenance of dentures are essential for their longevity and proper fit. Neglecting regular cleaning and not following the dentist’s instructions for care can lead to deterioration of the dentures and subsequent fit issues. 
• Changes in Oral Health: Oral health conditions such as gum disease or other dental issues can lead to changes in the oral tissues, affecting the fit of dentures.
• Accidents or Trauma: An accident or trauma to the mouth, gums, or jaw can alter the shape of the oral cavity, making the dentures no longer fit properly. 

Why is it important to Reline or rebase your dentures at the correct time? 

Denture reline is a dental procedure that involves modifying the inner surface of a denture to improve its fit and comfort and its shape of the oral tissues, including the gums and underlying jawbone, can change, leading to a loose or ill-fitting denture. Reline procedures help address this issue by adapting the denture to match the current contours of the oral cavity. Relining the denture  helps address these issues by customizing the denture’s inner surface to match the current contours of the mouth.

Denture rebase is another dental procedure performed to improve the fit and function of dentures, but it differs from denture reline in terms of the extent of modifications made to the denture. Unlike relining of dentures, which involves adjusting the inner surface of the existing denture to match the current shape of the oral tissues, denture rebase materials Denture rebasing is a dental procedure that involves replacing the entire acrylic base of a denture while retaining the existing denture teeth. 

Reline and rebase are two essential procedures for maintaining the proper fit and function of dentures. They help ensure that the dentures remain comfortable, stable, and functional. Here’s why it’s crucial to have dentures relined or rebased at the correct time:

• Improved Comfort: Changes in the jawbone and oral tissues can cause dentures to become loose or uncomfortable. Reline or rebase procedures adjust the inner surface of the denture to match the current shape of the oral tissues, providing a better and more comfortable fit. 
• Enhanced Stability: Loose-fitting dentures can lead to difficulties in speaking, eating, and social interactions. Reline or rebase procedures help improve the stability of the dentures, reducing the risk of them slipping or moving during everyday activities. 
• Better Chewing Efficiency: Ill-fitting dentures can compromise the ability to chew food properly, leading to digestive issues and poor nutrition. Reline or rebase procedures help restore the dentures’ proper fit, allowing for better chewing efficiency and digestion.
• Maintaining Oral Health: Poorly fitting dentures can cause friction and pressure on the oral tissues, leading to sores, irritation, and potential infections. Relining or rebasing procedures redistribute pressure evenly, reducing the risk of developing oral health problems.
