Patient: The lower row of teeth is protruding. What is the approximate cost? Doctor: First of all, you need to identify the cause of the diastema, and then you need to have an examination, take dental impressions and cephalometric radiographs for analysis, which cost about several hundred dollars. The treatment is usually surgical and is due to an imbalance between the upper and lower jaws. Orthodontic (“braces”) treatment must also be performed before and after surgical treatment, which is costly, about$50,000-$100,000, and takes about 2 years to complete. If it can be corrected by simple orthodontics, the cost is about$20,000 and the correction time is 1.5 to 2 years.
