Back in to see Dr. Tang yesterday. He filled a cavity earlier in the year yet there was some underlying, mild pain a few months later. Though it was likely stress related, Dr. Tang did ex-rays and found nothing to indicate the cause of the discomfort, yet still slightly reshaped the surface of the affected molar, and didn't charge me. This place is the best. Even if I lived in Seattle I'd still fly to Vegas to see Dr. Tang and his amazing, extremely friendly staff.
