Patient: I have a tooth on the left side of my upper incisor that is growing outward and I would like to have it orthodontically corrected, now that I am 30 years old. Thank you. Patient: Yes, how long will it take? How much does it cost? Thank you. Do I need to go to a comprehensive treatment center in advance to have my other dental problems treated? Please give me some guidance in your busy schedule, thank you.

Patient: Roger, thank you very much.
