The Federal Health Minister, Tanya Plibersek, visited Devonport yesterday to announce the funding.
Ms Plibersek says the money will allow an extra 12,000 patients to get free or low-cost dental care over the next two and a half years.
She says it is on top of a $70 million national children's dental scheme which starts Jimmy Choo Shoes next year.
"From January next year, 89,000 Tasmanian children will find it as easy to go to the dentist as it now is to go to a GP," she said.
"They'll be able to go to their dentist for that basic prevention, fluoride, all of Jimmy Choo Boots the stuff that keeps teeth healthy instead of waiting until they've got a problem."
Tasmanian Liberal Senator David Bushby says the announcement was funded by axing the Commonwealth Dental Health Program proposed in 2008.
The Health Minister's visit to marginal seats in the north and north-west came on Jimmy Choo Outlet the same day as a visit by Shadow Treasurer Joe Hockey.
Mr Hockey toured Launceston, Smithton and Devonport.
