Dr. Swang is a nice person, but he does poor work. I had 6 fillings done a year ago by Dr. Swang. After the fillings were done, he took x-rays of the completed work. Also, I complained that my teeth were very sensitive to hot and cold and did not fit together right when biting down. I went back more than 4 times for "adjustments." Dr. Swang felt that he did a good job, but I was not sure. So, I took my x-rays to two other dentists who confirmed that he did not do a good job. One dentist even said, "he did a hack job on your mouth". I had multiple leaky fillings. Now, as a result of his poor work, I have to have multiple fillings re-done one of which will require a crown. In addition, I have to have a root canal, because he did not put a filling in a tooth that clearly needed it a year earlier. Because of his poor work, I am going to have to pay over $3,500 above what my insurance covers to get my teeth fixed. Dr. Swang is a nice man, but I would never recommend him to anyone.
