How much is the hoop tooth? About how long?
Generally speaking, a good one costs 1000 yuan or more. But not too far off the mark. If you have time, it depends on whether your teeth are numb, but it varies from person to person. It usually takes one or two years, and it may take two or three years if it is not good. If it's just a small problem, it will be solved in half a year, right?
