Primary school children will benefit from free dental checks in a bid to help prevent tooth decay later in life.
The NSW government launched the health initiative in July this year.
Mobile clinics will visit schools as part of the NSW Health Primary School Mobile Dental Program, which will provide basic dental care thanks to an investment of $70 million across four years.
Premier Gladys Berejiklian says the dental program builds on existing NSW public dental services that make dental care available to all Medicare eligible children for free.
"This program will bring NSW Health dental practitioners into NSW primary schools, to make it easier for children to access vital services," she said.
Health minister Brad Hazzard says thousands of children are admitted to NSW hospitals every year with potentially preventable dental conditions and this program could reduce presentations.
"Children's oral health can influence their general health," he said.
"A healthy mouth ensures kids can eat, speak and socialise without discomfort and embarrassment, so it's important that we treat and teach them about oral health early."
Children will also be offered a teeth clean and x-rays to look for decay. The program initially focuses on western Sydney, the mid-north coast and the central coast before it is rolled out to other regions.
