Dr. Lee advised me to take Advil and wait to see if my tooth still hurt after I complained of intense discomfort after he said he saw nothing in the x-rays and he had tapped on my teeth a bit with a metal tool. I went to another Dr in the city Sunday as the pain had become unbearable. He performed a hot cold on the tooth, pressed hard up on the teeth with his finger, and did the metal tap test. He concluded I'd need a root canal as soon as possible. I had one Monday morning and after further x-rays it was discovered that an abscess was beginning to form and it was confirmed that the nerve was totally dead. I don't feel like the Dr at Jang was adequately trained, or just not concerned enough, to accurately diagnose my tooth. He seemed pretty nonchalant about the whole thing. I felt like your office just wanted to print money by taking x-rays, and didn't really care about figuring out what was going with the tooth. I definitely would not come back or recommend this place.
