Following initial checkup Dr. Martinez recommended 3 fillings for my 5yo son. After having other dentists look at the x-rays we decided to have Martinez do the fillings. The first two were done efficiently, in separate visits, and seem to be fine, although it's only been a few months. Before the 3rd one I found out that most resins contain BPA, which is an estrogen-mimicking petrochemical and suspected carcinogen. I asked Martinez if we could use a BPA-free resin, several of which do exist, and he completely ignored me. Even a few months after we cancelled the appt, no one from the office has even called about rescheduling. The guy seems to be raking in too much money to be bothered with questions. Very poor customer service, and, since he blew us off, it's taken some time to find another dentist, so that third cavity is now causing serious pain, so treatment success is also poor. Don't go to Martinez unless you and your kid are good sheep afraid to ask questions.
