Listen to me! If I can give Dr Chang 100000 stars! I would! If you're looking for someone to do a root canal or a root canal re-treatment do yourself a favor and run not walk over to him! Let me do a bit of explaining here. 10 years ago I had a terrible root canal done by a dentist in Bellflower ca. I knew at the time it was a really bad job and I wanted to take her to small claims court because she was just a horrible dentist and neglected all of my concerns. I've included pics for you to see here. Well a few moths ago, my dentist told me that the root canal has indeed failed and that I had to go get a re-treatment done or take the tooth out and get an implant. I was a bit skeptical because of my previous experience. But Dr Chang was totally amazing! I was so anxious about the procedure but day off I was knocked out. I actually fell asleep during my procedure. That's never happened at any dental appointment before. He listens to your needs and finds a good middle ground with no high expectations. He doesn't lie to make you feel good and then mess you up. He's truthful, honest and very kind. He was so so thorough and basically kicked ass! He completely gave me a root canal make over. I'm so thrilled that I left the appointment and writing this review in my car. Thank you so much Dr Chang! You really helped me through this process with so much grace and kindness. I really appreciate everything! Ps. You can SEE the results for yourself! read more
