Temporary dentures are a prosthetic solution designed to bridge the gap between tooth loss and the placement of a final, permanent restoration. These appliances are intended for short-term use, acting as a placeholder while the mouth undergoes a significant healing phase following tooth removal. They ensure that individuals do not experience a period without teeth, which is important for maintaining both appearance and function. This transitional device allows the patient to maintain a relatively normal life while their oral tissues stabilize before the final denture can be precisely fitted.
Defining the Purpose and Types of Temporary Dentures
A temporary denture is a stand-in device that serves several purposes immediately following the extraction of natural teeth. They are most commonly referred to by dental professionals as “immediate dentures” or “interim dentures” because they are inserted on the same day as the tooth removal procedure. Their primary function is to maintain the patient’s aesthetics and ability to speak and chew immediately after the teeth are gone. Temporary dentures also act as a protective bandage over the extraction sites, helping to control bleeding and shield the sensitive gum tissues from irritation and food particles. These prosthetic solutions come in two main forms: a complete denture, which replaces an entire arch of teeth, or a partial denture, which replaces only a few missing teeth.
The Necessity of Immediate Placement During Healing
The immediate insertion of a temporary denture is a strategic approach to managing the biological changes that occur after teeth are extracted. Tooth sockets and the surrounding gum tissue require several months to fully heal, stabilize, and remodel. Placing the denture immediately helps to maintain the correct spacing and alignment of the jaw structure, supporting the facial muscles and preventing a sunken appearance. The underlying jawbone, or alveolar bone, begins to shrink and deteriorate after tooth loss, a process known as bone resorption. While the temporary denture cannot fully stop this natural shrinkage, it provides continuous pressure that may help preserve some bone shape and density during the initial healing period.
Structural Differences from Conventional Dentures
Temporary dentures differ from their final, conventional counterparts in several structural and material aspects. They are fabricated using impressions taken before extractions, meaning their initial fit is an approximation of the healed tissue shape. This is in contrast to conventional dentures, which are crafted from impressions taken after the gums and bone have fully stabilized. Because the mouth changes significantly during healing, immediate dentures are inherently less stable and require frequent adjustments, often involving the application of soft liners. These liners cushion the extraction sites and fill the gaps that form as the tissues shrink, and the materials used are designed for ease of modification and repair rather than long-term durability.
Practical Considerations for Daily Use and Care
Patients should expect an adjustment period when first using temporary dentures, which can include initial discomfort, soreness, and difficulty with chewing and speaking. For the first 24 hours, the denture is advised to remain in place continuously, acting as a pressure bandage to help stop bleeding and reduce swelling. After this initial period, the denture must be removed for cleaning. Proper care involves gently brushing the device daily with a soft-bristled brush and a non-abrasive cleanser, avoiding regular toothpaste which can scratch the material. When not worn, the dentures must be stored in water or a soaking solution to prevent warping. Due to the less stable fit, follow-up appointments are necessary for relining or adjusting the denture to accommodate the ongoing tissue changes, and patients are advised to eat soft foods initially.
