Dr. Buchanan saved me from prolonged pain, needless expense, and months of waiting for a good solution. To explain, my general dentist misdiagnosed my need for root canal therapy. While completing my root canal, Dr. Buchanan did something I find all too rare: He listened. As a result, he found an infection that, because he addressed it immediately, could be treated without extensive oral surgery. I traveled to Santa Barbara twice to be treated by Dr. Buchanan and it was the best decision I could have made.
