Graduated with low GPA, out of school for 4 years now. What should I do?

I graduated with a 2.6 biology major 3 years ago and have been out of school since. After working, now I’m really trying to get into Dental school and not sure what steps I need to do. I’ve applied to some local graduate programs but have been denied. What should I do? What can I do to put me on a fast track to Dental school? Any advice is welcomed, thank you!
