Which is better, Xi 'an North Street Jiaotong University Stomatological Hospital or the Fourth Military Medical University Stomatological Hospital? I heard that the Fourth Military Medical University charges a lot of money. I don't know how expensive it is. It's quite expensive, but it is fully functional, and the division between periodontal disease and orthodontics is very detailed. If it's expensive, it seems that root canal treatment costs thousands (300 in a small hospital), dental crowns cost thousands to 10,000, orthodontics costs about 40,000 (6000 in a small hospital), subgingival scaling costs thousands, and tooth extraction costs thousands. If you plant a tooth, it costs 20 thousand yuan, not counting the upfront cost (bone grafting or something), just the finished tooth.
