Dr Porter is simply the best! He uses state of the art technology without exception. He and his staff are top notch. Our whole family, grandparents to kids go to Dr. Porter. I unconditionally recommend and trust him. He operates the machine which can allow you to leave with a new crown the day you go in...NO temps! Even his novacaine injector is computerized. It controls the speed and pressure of the novacaine going in, which in turn keeps it from hurting :-). His equipment is truely amazine. His chair-side manner is respectful and he loves to share what he's doing and how his technology works. He is the man!
