The charge for filling teeth in Guangzhou is based on the number of cavities. If there are several holes in your teeth, you will pay for them. A cavity in 80 yuan is between 65438 and 020 yuan, depending on the specifications of various stuffing shops. If it can't be filled at one time, it needs disinfection, that is, a hole is between 65438 and 65438 and 050 yuan. Like your situation. That is to say, the minimum cost 180 yuan. If it's not rotten, I don't recommend dental implants. The price is high, at least 1000 yuan, and the eating effect is not as good as the original teeth. Or the last braces, 100 yuan to several hundred yuan. In addition, I tell you that some dentists in Guangzhou will try their best to let you use expensive materials when you fill your teeth, which is the so-called "high-priced materials". Besides, you are a student, so try to spend as little money as possible. In addition, if your teeth are thin, I don't recommend you to wash your teeth, which is easy to crack. I feel my teeth are thin after washing myself. How long does it take to fill a tooth? If you don't need treatment, you can do it at once, about half an hour. According to your situation, you should have root canal therapy, usually 3-8 times, depending on your teeth. You need to sterilize your teeth until they are not inflamed (about 20 minutes each time, once every other day) and painless, and then try to fix them (about 30 minutes). In about a week, you will be sure.
