LF a cheap and gentle dentist. No income, no ID

Just as the title says, I have intense tooth and jaw pain on one side. I haven't been able to eat for a day or two and ibuprofen does nothing. I have no insurance, no income, no ID (long story) I have some cash I have scrounged together and might be able to pull more from parents overseas but it wont be fast. I'm worried and in constant pain. Does anyone know somewhere where I can get this looked at and dealt with. More than likely needing a root canal. I'm in Cypress and can access anything in north west Houston.
