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:
At first, wearing dentures may require some getting used to in terms of talking and eating, as the dentures become “balanced” in the space formerly occupied by the teeth. But over time, the muscles, nerves and ligaments of the mouth learn to work in new ways, which allows these functions to occur normally. Dentures also help support the facial skeleton and the soft tissues of the lips and cheeks, which can help create a more youthful appearance.

I have both upper and lower dentures, but the uppers, which are newer, are very white compared to the bottoms. It will cost me a lot (like $500) to replace them, but I want them to match. Can I whiten my dentures?Answer: It is not possible to whiten dentures like natural teeth because dentures are made of plastic. To minimize staining, properly clean your dentures daily to remove food and plaque bacteria. Brushing with a denture brush or soft toothbrush will prevent dentures from becoming permanently stained and will keep your mouth healthy. Moisten the brush and apply a nonabrasive denture paste (regular toothpaste is too abrasive) or use liquid soap. Brush every surface, inside and out, scrubbing gently. A variety of over-the-counter denture-cleanser products may be safely used (by following the manufacturer’s instructions) to remove some stains. You may also consider soaking your dentures in a cup of water with a teaspoon of household bleach, but be sure to rinse them off well before putting them back in your mouth. When cleaning your dentures, be careful not to drop them as they can break. You should clean your dentures over a sink that is filled with water or has a washcloth in place to prevent the dentures from breaking should you drop them while cleaning. More stubborn stains may require removal by your dentist or prosthodontist, a specialist in denture care and maintenance. To locate a prosthodontist near you, visit www.gotoapro.org.

Full or partial dentures consist of a gum-colored base made of plastic resin, which fits over the remaining alveolar (bone) ridge that formerly held the teeth. The prosthetic teeth projecting from the base are designed to look and function just like your natural teeth. Dentures are held in place primarily by the suctioning effect of their close fit against the alveolar ridges — that's why it's so important that they are fitted properly. The upper denture also gets extra support from the large surface area of the roof of the mouth (palate), which generally makes it extremely stable.
An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
