Removable dentures are prosthetic devices that replace missing teeth, restoring the ability to speak, chew, and smile confidently. While designed for all-day use, they are generally not intended to be worn continuously, especially during sleep. The professional consensus strongly advises against sleeping with these devices, as this guidance is rooted in the need to maintain the long-term health of the oral tissues. Understanding the specific reasons behind this recommendation and adopting a proper nightly routine are key.
The General Dental Guidance
Dental professionals advise removing dentures for six to eight hours every 24 hours, usually overnight. This removal period gives the underlying tissues a rest from the constant pressure exerted by the device. Dentures press directly against the gums and bony ridges, restricting natural circulation and saliva exposure.
Allowing the tissues to breathe and recover prevents chronic inflammation and soreness. Nightly removal restores natural protective functions, aids saliva flow, and reduces the chance of painful pressure spots.
Health Consequences of Continuous Wear
Wearing dentures continuously fosters negative health outcomes. A frequent issue is denture stomatitis, characterized by inflammation and redness on the palate. This is a fungal infection caused by an overgrowth of Candida albicans, which thrives in the warm, moist space between the denture and gum tissue.
Continuous wear also accelerates jawbone loss, known as bone resorption. Constant pressure on the alveolar ridge speeds up the natural shrinking of the jawbone following tooth loss. This bone loss changes the mouth’s contour, causing the denture to fit poorly, leading to looseness and reduced stability.
A systemic concern, especially for older adults, is an increased risk of aspiration pneumonia. Bacteria and fungi multiply rapidly on the denture surface. When worn during sleep, these microorganisms can be inhaled into the lungs, increasing the risk of respiratory infection.
Proper Nighttime Cleaning and Storage
Instead of sleeping with the prosthetic, the nightly routine should focus on cleaning and storage to protect both the mouth and the device. Thoroughly clean the dentures before bed to remove accumulated food debris and plaque. Use a soft-bristled brush designed for dentures and a non-abrasive denture cleanser or mild soap.
Avoid using regular toothpaste, as many brands contain abrasive ingredients like silica that can scratch the denture material. These microscopic scratches can harbor bacteria and make the prosthetic difficult to clean effectively. After brushing, the denture should be stored fully submerged in clean water or a dedicated denture-soaking solution.
Keeping the device moist is necessary because the acrylic material can dry out and warp, which would compromise the fit. Lukewarm water should be used for soaking, as hot water can permanently distort the shape of the denture. A clean container should be used for storage to ensure the prosthetic remains hygienic overnight.
