Dentures are generally worn during the day and taken out at night to give the oral tissues time to relax. During the first few days after receiving the denture, however, it needs to remain in the mouth even when sleeping to best identify areas that need to be adjusted. This is especially important after receiving an immediate denture, for the gum tissues will swell after the teeth are extracted or lost and then may not permit the denture to be reinserted if taken out.
Support is the principle that describes how well the underlying mucosa (oral tissues, including gums) keeps the denture from moving vertically towards the arch in question during chewing, and thus being excessively depressed and moving deeper into the arch. For the mandibular arch, this function is provided primarily by the buccal shelf, a region extending laterally from the back or posterior ridges, and by the pear-shaped pad (the most posterior area of keratinized gingival formed by the scaling down of the retro-molar papilla after the extraction of the last molar tooth). Secondary support for the complete mandibular denture is provided by the alveolar ridge crest. The maxillary arch receives primary support from the horizontal hard palate and the posterior alveolar ridge crest. The larger the denture flanges (that part of the denture that extends into the vestibule), the better the stability (another parameter to assess fit of a complete denture). Long flanges beyond the functional depth of the sulcus are a common error in denture construction, often (but not always) leading to movement in function, and ulcerations (denture sore spots).
The safe, healthy choice is to not sleep with your partial denture in place. Sleeping with partial dentures is not recommended for a number of reasons. Partial dentures are designed to be cleaned outside the mouth – which also provides the opportunity to ensure no food particles are lodged under or around the partial. Proper oral care and keeping you partial denture clean is vital for the overall health of your gums. From a physical standpoint, your gums will benefit from the opportunity to rest and recover. Also, some patients may clench their teeth in their sleep. This pressure can cause damage to both natural teeth as well as dentures.
Most partial dentures contain a thin metal framework that is designed to rest close to your gums and allow for a smooth, non-bulky feel. The framework is supported by your natural teeth to provide a reliable, secure appliance that is easy to use. Where teeth are missing, natural-looking replacement teeth are attached to the frame, and gum-colored acrylic is used to make the appliance blend with your mouth. Again, your mouth and your needs are unique, and Dr. Yonan, Scott, Quigley, Fairbanks & Bushnell work with skilled technicians to create a solution that is comfortable and esthetic.
Teeth can fall out for a number of reasons, ranging from genetics to drug abuse. Most commonly, teeth are removed or fall out on their own due to severe tooth decay. Neglect to upkeep oral hygiene or not seeking proper treatment for damaged teeth, can lead to the onset of decay which in turn leads to loss of teeth. Visiting you dentist in 6 month intervals is a good preventive measure to spot any early signs of decay.
