I did the correction in the Stomatological Hospital of Medical University. The doctor said the cost was 1.2- 1.5 million. Excluding tooth extraction and filling. Five teeth were pulled out 1, more than 300, then one tooth was filled with 200-300, and then one tooth was treated with root canal, and one root canal was 500-600 (I dare not calculate the total cost of making a crown later). I expect I will wear braces for two to two and a half years.
