If you have a dental plan, check with them first to see if they reimburse for care in Mexico. Some plans do provide coverage (reimbursement not direct bill) for care at select offices in Mexico providing the dental office properly completes the paperwork. I know someone who used Castle Dental in Los Algodones and the office completed the insurance paperwork and provided copies of the documents required. He submitted the paperwork to his US dental insurance, and they reimbursed him a sizable portion.
