I was told by my dentist that I may have a crack in my tooth where he had started a root canal and there was a  good chance I may loose my tooth. he said it would be best if I went to see a specialist, Dr. Lu  I was nervous apprehensive. I  have been going to the same dentist since I was 5, I trust him, I'm comfortable and secure when I visit him. I had nothing to fear evidently. Within 5 min of walking into Dr. Lu's office, I felt like family. There office is beautiful and Dr. Lu's assistant, Charlie, pulls double duty as an office manager making the process seam all the more seamless. Being greeted with warmth and a smile is only the first half, and while essential in my book, I came here for my tooth to get fixed. Dr. Lu impressed once again.
