Full-time college Student who would love to smile at Graduation

I am a 22 year old full-time college student in New York, and will be graduating in May. The problem is I am uninsured and cannot afford dental work that would enable me to speak to others much less smile at graduation. I have been on medicaid in the past a had dental work done, but it has just exacerbated the problem. One dentist did a root canal and then just stuck Temperin in the space, needless to say it did not last long and now the front tooth has broken. I have tried financing options but do not have the credit necessary to secure plans like care credit, captial one. I need extensive dental work, but would be happy with just the front tooth fixed. My mother and sister also struggle with dental problems, and have encountered the same problems I have. My hope by posting this plea is to find a dentist or someone to help my family and me get the dental care we desparately need. We have worked hard, but this is one expense we cannot take on by ourselves. Any assistance that could be provided would be greatly appreciated.
