Re-designates a portion of the PHSA to include support and development of dental training programs. Toward this end, authorizes the Secretary of HHS to make five-year grants – subject to annual approval and funding availability – available to or enter into contracts with schools of dentistry, public or nonprofit private hospitals, or a public or private nonprofit entity deemed appropriate by the Secretary to, among other things, carry out these professional training and loan repayment programs. Further delineates eligibility as well as award preference criteria (e.g., applicants with a track record of training individuals who are from rural or disadvantaged backgrounds, or from underrepresented minorities). Authorizes to be appropriated (but does not delineate a separate Congressional appropriation) $30 million for FY 2010 and such sums as may be necessary for each of FYs 2011-2015. Further delineates requirements relative to the ability of awarded entities to carryover funds from one year to another.
