I also heard that there may be pain problems in treatment, which made me hesitate for a long time. Finally, through a friend's introduction, I found the Angel House Clinic of Riel Dentistry. This clinic has convenient transportation, elegant environment and complete facilities. Shang Chen, the orthodontist who received me, left me a very good first impression. He speaks methodically, logically and professionally. His manners and manners show his love and professionalism for his work. What makes me more at ease is that I heard that Dr. Chen is a doctor from Capital Medical University. After working in Riel for seven years, I have accumulated rich clinical experience and won the trust and praise of many customers.
