The only DAT scores sent on their own are the 5 that you designate on the form you submit to ADA right before taking your exam. You have to fill out a separate (online) form and submit the $15 fee for every school after that. Furthermore, dental schools want fresh info every app cycle, so if you didn't retake the DAT, you will probably have to re-send your scores to the schools you applied to in a previous cycle at a cost of $15 per score sent... with no free scores sent at all. Hope this makes sense.
