Do you know of any affordable dentist in San Diego?

We have no insurance and my gf is having a toothache and a cracked tooth. We checked out one Vietnamese dentist and he wanted almost 2000 dollars. My God! That is a lot of money. So, if you know any affordable dentist any where, please let me know. We'll be paying cash. I suggested Tijuana, but she's afraid of going there. Thank you in advance.
