Your dentist or prosthodontist will instruct you as to how long to wear dentures and when to remove them. During the first several days after receiving your denture, you may be asked to wear it all the time, including while you sleep. Although this may be temporarily uncomfortable, it is the quickest way to identify the areas on the denture that may need adjustment. Once adjustments are made, you should remove dentures before going to bed. This allows gum tissues to rest and allows normal stimulation and cleansing by the tongue and saliva. The denture can be put back in the mouth in the morning.
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.
