grad school (dental) acceptance harder than undergrad?

<p>Is it considerably more difficult to get into dental school than undergraduate? According to my dad (who went to Tufts dental), perhaps only 5-10% make it. I'm pretty sure I want to apply to dental also, but I'm afraid I might not make it after I finish undergrad :S! I'm attending Wellesley as a biology major btw, thought I don't know how much a role being in a LAC will help ...</p>
