A number of vital tasks carried out during sleep help maintain good health and enable people to function at their best. Sleep needs vary from individual to individual and change throughout your life. The National Institutes of Health recommend about 7-9 hours of sleep each night for older, school-aged children, teens, and most average adults; 10-12 for preschool-aged children; and 16-18 hours for newborns. There are two stages of sleep; 1) REM sleep (rapid-eye movement), and 2) NREM sleep (non-rapid-eye movement). The side effects of lack of sleep or insomnia include:
^{Some partial dentures are made almost entirely of acrylic – but just like metal framework dentures, acrylic dentures have wire clasps that attach to any remaining natural teeth. These are generally used as a cost-effective alternative to metal-based partial dentures. They can also be used for transitional dentures when you’re expected to have additional prosthetic treatments, such as implants, in the future.}
Although traditional dentures will provide more biting force than a mouthful of missing teeth, it is still far less than can be achieved with real teeth - or implant-supported dentures. Dentures that are anchored by dental implants will triple the patient's biting force, when compared to traditional dentures, making it easier to eat crunchy, tough, and chewy foods. In addition, implant-supported dentures will not move out of place, even when pressure is applied to the prosthetic when eating.
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.
Fifty-four complete-denture wearers were interviewed one year after they had been fitted with the dentures. Their opinions and reactions were noted and the answers given to standard questions were analysed for inter-correlations and for correlations with findings in earlier series of clinical and roentgenological investigations. Most of the patients were satisfied with the fit, aesthetic effect of the denture and ability to chew and speak. Many of the patients reported oral parafunctions. Roughly every fourth patient used sedatives because they felt restless and nervous.

Removable partial dentures are for patients who are missing some of their teeth on a particular arch. Fixed partial dentures, also known as "crown and bridge" dentures, are made from crowns that are fitted on the remaining teeth. They act as abutments and pontics and are made from materials resembling the missing teeth. Fixed bridges are more expensive than removable appliances but are more stable.

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.
