SDN Members don't see this ad. (About Ads) If you have not started dental school, can you apply for a 3 year scholarship instead of a 4 year one? Or is it only awarded to first year dental students and those that did not get the 4 year one? I am thinking of a career in dentistry, but am not sure how my family situation will be. I know there is not be a big difference between a 4 year commitment vs a 3 year commitment, but it is still a difference.
