Western Dental advertises credit for everyone, and they will give it. However the down payment is quite large.
I was also not impressed with the standard of care I received there. My request for a female dentist was not honored. The work seems substandard. My concerns about things were brushed off.
I ended up not getting the last item (a wisdom tooth extraction) done there and closed off my account. I had paid in full so they owed me money, and it took months and many visits and phone calls to finally receive it.
I would not recommend them unless it's an absolute emergency!
