Proper denture care and cleaning can be difficult, and with aging the gums can change, leading to problems with denture fit. People with dementia will need assistance with dentures and plates, as the importance of hygiene cannot be overstated.

Dentists with experience with elderly patients are usually more skilled in identifying and dealing with dememtia, as well as adapting to their patients’ hearing loss, vision loss, and so forth, and may also be ready to engage with caregivers for elderly patients. Communications techniques and tools on the practioner’s side are very important.

Physical challenges

Financial challenges

In many cases the financial situation of elderly people will present challenges for dental care. Retirement might lead to the loss of dental coverage, and elderly persons on fixed incomes might lack the necessary supplemental dental coverage.

Preventative measures can include fluoride gels and tooth varnishes.

Natural consequences of aging

While dry mouth is not a requirement of aging, it nonetheless affects 30% of patients older than 65 years and up to 40% of patients older than 80 years.

Increased gastric pH that can accompany aging can lead to acid reflux that can be damaging to teeth.

Also, increased gingival recession that exposes root surfaces is a potential problem for the elderly, and loss of nerve sensitivity with age can give cover to dental problems that should receive early detection. Elderly people might just not feel developing tooth problems.

Among the elderly there is increased incidence of mouth, throat, tongue cancers and dentists need to be aware of this risk. The average age of diagnosis is 62; meaning that vigilance is important.
