What do you feel an Ivy League dental school (Harvard, Columbia, or Penn) would offer you that another school wouldn't? For example - Boston U or Tufts, NYU or Stonybrook, or Temple - all located in the vicinity of each Ivy.
Not to be negative... however, a 20/16 is an extremely normal score. Your 16 PAT and 14 Math are sub--par at best. Nearly all schools will look at other factors (research, motivation, experience, maturity, etc...) that are just as important, but at the Ivy level any sub-par areas are that much more noticeable. Apply to them but definitely apply to several state schools as well.
