Help Restore My Smile And Confidence

I recently lost my back teeth and now my front teeth are starting separate and my front tooth is trying to get loose. I do not have the means to replace my teeth so here I am asking for help. I do have insurance, but the insurance is not covering anything in order to eat a regular food again I will need your help! I’ve been very insecure about my smile and even sometimes talking to people cause I’m embarrassed of my teeth.
