I'm a student and can't afford urgent dental care I need

Hi, I'm a student and have applied for a Hc1 form and ended up with hc3, which won't help me. I have a genetic predisposition to brittle/weak teeth. One of my back molars broke off partly a month ago and I can't afford to see a dentist and don't know what to do. My parent can't help me financially, I work and have a student loan but it's just no enough to afford the help I need. I genuinely don't know what do at this point. Are there any other options? Or do I just leave it until it's so bad that the nhs can help. Need any advise please.
