The price of provincial and municipal stomatological hospitals is reasonable ... if you meet a private specialist hospital, the price will go up. Now your charge is basically three tubes of 900 yuan. This kind of hospital is not a private clinic, so it is difficult to bargain ... I can't help you in this respect.
As for reimbursement, it depends on whether the hospital is linked to the medical insurance center. Generally speaking, as long as it is not a small private clinic, public or specialized hospitals can enter medical insurance, but the items that enter medical insurance are different. For example, tooth filling and tooth extraction like yours are personal medical projects, but if they are cosmetic projects such as tooth whitening and porcelain restoration, they cannot enter medical insurance.
