Have been using Millennium for 11 years, never had a bad experience in exams or with work done. The other evening, I had a tooth make a noise. The next morning I felt it cracking while driving to work. Called the office and was in the chair in one hour. The tooth was worse than I thought and needed a crown, which they basically did right then over lunch. They are always friendly in the office and in the chairs, but now I know that when I need them in a pinch, they are there!
