The good habits of effective daily brushing, flossing and diet will help the mature person adapt to changing conditions. Reduced salivary flow and addition of medications will affect oral health dramatically.
Changes of the teeth and gums: Teeth will darken because of long-term exposure to plaque. The gums may recede and uncover the roots. Exposure roots will be darker than the enamel part of the tooth and are prone to decay. Fillings can decay and darken, too, as they weaken over time.
"Dry Mouth" may develop: Saliva is useful to lubricate, wash away plaque, and neutralize the acid produced by plaque. Flow of saliva can be reduced by a medical disorder or be a side effect of antihistamine, decongestants, pain killers or diuretics.
The build-up of plaque will accelerate tooth decay. There will also be more gum infection which will cause a loss of bone support for the teeth. Poorly-fitting partials, worn or chipped teeth, illness and some medications increase the severity of the problem
