Dentition, Oral Hygiene and Its Importance


A healthy mouth is one that is free from pain and infection, with no untreated tooth decay and with pink gums that does not bleed on brushing. The mouth should be moist, with no lumps, ulcers or unusual color.

Problems among the elderly and oral health are as such:

Discolored teeth

Caused by changes in dentin, consumption of stain causing food and drinks and also by thinning of the outer layer of enamel.

Dry mouth

Caused by reduced saliva flow. This happens for various reasons e.g. Sjoren’s syndrome, post radiation to head and neck area as well as side effects of medication.

Decay of root

Caused by exposed root of tooth, as gum recedes from the tooth and since its not protected by enamel, it is prone to decay.

Tooth decay

Reduced sense of taste

Advancing age impairs the sense of taste, disease, medications and dentures contributes as well.

Gum disease

Caused by plaque and made worse by food left in teeth, use of tobacco products, poor-fitting bridges and dentures, poor diets, and certain diseases, such as anemia, cancer, and diabetes. These are common diseases encountered by the elderly.

Tooth loss

Gum disease is a leading cause of tooth loss.

Uneven jawbone

Caused by tooth loss with no replacement of missing teeth. This leads to the rest of the teeth to drift and shift into open spaces.

Importance of oral hygiene

Germs colonize dental plaques in the elderly whom are dependent. These act as a specific reservoir especially if the elderly aspirates and ends up with lung infection. Lung infection can be a life threatening condition and it is a significant cause of morbidity and mortality.
