Dental Statistics (Australia & Worldwide)

On this page we keep a record of interesting oral health statistics that we come across when researching various topics.

These are mainly dental statistics about Australia, but we have also included some that apply globally.

We only reference reliable sources, and credit them after each statistic.

Sometimes the original source may be deleted from the internet, in which case we keep a record here but include a caveat that the original page was deleted.
