I love Dr. Tehrani; I've been to several dentists in the past few years, and he is by FAR the best in the Dallas/Plano metroplex. He is so knowledgeable, gentle, and kind, but a perfectionist at his technical craft. He did a root canal and re-did several crowns for me that two different dentists had done incorrectly, and I had NO pain, even after the root canal. It doesn't even hurt when he injects the novacaine the first time (unlike other dentists, where the sting is horrid). And the crowns he did look exactly like my teeth and fit perfectly. His skill as a dentist is just on a higher level than any other dentist I've gone to. He told me that some dentists accept mediocrity -- ie., crowns that only last a few years -- but that is absolutely not acceptable to him. I am actually grateful that I have had average to below-average dentists before, or I might never have found Dr. Tehrani, who is SO much better. On top of all that, he has beautiful facilities - light, airy, and spotless -- right off Plano Parkway and a great, friendly staff. I am not easy to please, and I have nothing but extremely positive comments about him. I recommend him most highly, even if you think your dentist is OK, as Dr. Tehrani is far better
