① Age gap: There are differences in age. If you are young and the alveolar bone is not well developed, it will be easier to correct, the length of correction will be shortened, and the price is naturally not expensive. When the adult alveolar bone develops, the correction will be relatively complicated, the length and difficulty of correction will increase, and the correction cost will naturally increase. There is no doubt about it.
② Oral health: Everyone's oral condition is different. If the oral condition is poor, there are pulpitis, periodontitis or tooth decay, and it needs treatment before it can be corrected. But it costs a certain amount of money and the price is different.
