Brushing, cutting down sugar and regular checkups are key, according to Bendigo dental nurse Nadine Drummond.

Ms Drummond is seeing fewer and fewer dentures in her line of business. She thinks education has been key in helping people keep their teeth.

Fluoridation of water has also made a huge difference, Ms Drummond said.

It's a pattern that's replicated Australia-wide, as more adults keep their teeth, according to the Australian Dental Association.

On World Oral Health Day the association called for Australians to think about how well they're taking care of their oral health.

"We're getting more and more elderly patients that come in and have all their teeth," Ms Drummond said.

Nearly a quarter of Australian children have experienced decay in their permanent teeth.

Over 15 percent of Australian adults have fewer than 21 teeth.

But the risks are still there. Sugary drinks is a big problem for teenagers, Ms Drummond said.

Some risky foodstuffs might even be a surprise. Ms Drummond sees parents in with young children who've been eating dried fruit, or drinking orange juice with added sugar.

The sugar from the dried fruit - often used in the likes of bliss balls - sticks to their teeth and causes problems.

Ms Drummond said education in childhood was key to keeping kids' teeth healthy.

"We're getting the kids on top of it at a young age, getting them into a good habit of brushing twice a day. It just becomes a good habit for them and then they follow [it] on into adulthood," Ms Drummond said.
