MPs are backing a call for a new training school for dentists to be built in Yorkshire as a way of improving the region's dental health.
Hull and York universities want to add a dental department to the existing medical school they jointly run.
Haltemprice and Howden MP David Davis has put down a Commons motion urging the government to approve the plan.
So far, 20 other MPs have added their support including Conservative Greg Knight and Labour's John Grogan.
"Yorkshire is one of the worst places in the country to live if you want to see an NHS dentist," Mr Davis claimed.
"It is well-established that dentists tend to practice in the area where they trained.
"That is why it is important that the government approves the bid by Hull and York universities to build a new dental school."
