A further two-full time and one part-time dentists are needed to cover the minimum.
Three full-time and one part-time dentists are covering the work of a minimum of seven people across Laois and Offaly.
Figures released by Sinn Féin TD, Brian Stanley, show the school dental scheme in the two counties is significantly understaffed.
The service is in need of a further two full-time, and one part-time dentist.
A new recruitment campaign is set to be advertised this month, with two evening sessions per week now available in Portlaoise to children on the waiting list, and two additional daytime sessions weekly in Tullamore.
Deputy Stanley says, while these measures are welcome, they are still not enough:
