Have you stayed in contact with the SNDA members at the Impressions Days? Are they giving you any advice about retaking the DAT? You're maybe a shade lower than I would prefer, but that doesn't mean some programs will summarily exclude you because of it.
You have hit the usual schools, though keep in mind DCG is very focused on their in-state pool. You may want to consider some privates like LECOM if you have Tufts/BU. URM's are desirable at most schools.
Have you connected with any local chapters of the ADA or NDA? Use connections from the SNDA members to find someone who is hiring for a good DA near you. You can do it, but you want someone who is supportive of you. The dentist you have interned with ought to be a good source for referrals.
