People who have elderly relatives have been encouraged to help them when it comes to emergency dentistry prevention.
Writing for the Windsor Star, Dr David Mady said "it is imperative that the elderly receive good oral healthcare on a regular basis", or they may develop problems such as decay.
Writing in response to a query from a reader whose mother is suffering from dementia, the expert recommended helping her to brush and floss her teeth.
He said it is best to use a soft-bristled brush and non-flouride toothpaste similar to that available for children if she tends to swallow it.
Dr Mady also stressed the importance of flossing, explaining that bleeding gums and possible infection could be the result if this is not done regularly.
He said automatic flossing tools are available for people who may be having problems with traditional floss.
Earlier this month, a study carried out in Japan and published in the journal Behavioral and Brain Functions found that elderly people who have to have dental implants because all of their teeth have fallen out may also be more susceptible to dementia.
