As someone who had a low gpa and is struggling in this dental journey with you, you can do this. A lot of people will say it's impossible to recover from a low gpa and it is hard, but doable. Make sure other parts of your application stand out and choose which schools your apply to carefully. I don't think it's possible to get a 4.0 with any non-A grades in your transcript, but I can tell you're aiming to raise it as much as possible.
EC's: definitely join your college dental/health clubs and try to get a leadership position if possible or just be more involved than a regular member. Volunteering and shadowing is important too, keep working in that research lab.
LOR's: I chose people who had different things to say about me. For example, I picked a prof who knew my work ethic/personality really well and another that could speak about my past bad grades and how I overcame them in their class. I'd choose a professor you connected with on a personal level rather than a prof you scored an A with, but doesn't really know you.
Honestly, low grades just mean you have to prove yourself and go above and beyond to really show that you have the passion and the drive. I agree with the person above, you'll want 20+ in all DAT subjects.
For me, getting interviews was REALLY hard because a lot of schools won't give you a chance based on the past grades, but I think you'll be okay if you can keep your gpa up from now on. This was just a slip up and coming back from it can help show your mental fortitude/ability to rise from a minor fall. Also, make sure your personal statement conveys your passion, endurance, and determination, etc. That is the one part of you app where you can actually explain things and kinda convince someone that you deserve a shot.
You've got this!
