Should go to the hospital. The main thing is to check whether there is inflammation in the root pulp, see if it is necessary to do some local anti-inflammatory treatment first, and choose the best filling time. Because filling teeth is not always done. If there is inflammation in the root or medulla, it may lead to systemic infectious bacteremia or aggravate local infection. Therefore, to see a doctor, even if it is filling a tooth, it is best to go to a regular hospital for examination before deciding where to fill it. If the clinic is run by the chief physician and the deputy chief physician, the equipment and hygiene can be trusted. Of course, it can be treated in such a clinic, which can save some expenses. However, at present, there are not many such trustworthy clinics in China, so we should be careful when choosing them, so as to avoid minor illness becoming serious illness. As for the fees, the fees vary from province to province. Simply filling teeth won't cost too much, so it should be around 200 yuan. If there is inflammation that needs treatment, it depends.
