There are always other factors at play, but I question the sentiment that community college coursework is widely frowned upon for dental school acceptance. Let's just let the premeds deal with that added worry of CC vs Uni for now!
For some anecdotal evidence, I'm a non-trad accepted to 4 schools out of 5 interviews this cycle and will have attended three separate undergraduate institutions by the time I complete my degree in May. I ended up at a CC for a year doing a good portion of prerequisite courses for cost saving reasons before finishing my BS at a university. I also split gen chem 1 and 2 between uni and CC (Yes, I started at a uni, went to cc, then returned to a cheaper uni thanks to employee tuition benefits.)
I was not questioned in any interview about my undergraduate schooling choices and I was careful to not select dental schools known to not accept community college courses -- which was easy because there are very few that do not accept them! There exists very thorough excel compilations on SDN listing dental school CC limitations, making selection even easier.
If quality of education from CC is a concern, do a little research on the professors teaching those courses at your local cc prior to enrolling. If you want academia qualification justification, the professor from whom I took orgo is an MIT PhD grad in some fancy specialty involving molecular conformation, as an example. He just wants to teach, and a CC lets him do just that. Similar situations exist for doctoral qualified anatomy and physio professors here, too.
In my experience, if you can prove to dental adcoms that you are able to handle upper division BCP courses from a Uni then there's very little reason to worry about spending a year at a CC for dental pre-reqs, regardless of splitting the courses. If questioned while interviewing, I'm sure you'll be tactful in your response.
