To tell the truth, the regular and technically good prices are not low. I had it mended at the Stomatological Hospital years ago. Three flowers were spent 1600, not counting braces. Mainly depends on the degree of damage to your teeth. If root canal therapy is needed, the cost will be more expensive. If root canal treatment is not needed, a tooth costs 100 yuan.
I suggest you treat it early. Filling teeth will be more painful and expensive in the future. I hope it helps you.
