The cost of orthodontics is generally related to your dental condition, and the most important thing is the material of the appliance you choose. The most common type of labial correction, commonly known as "Kouga", is about 20,000 yuan, and then it is invisible and then corrected on the lingual side. Generally, people who go to work, especially those who often talk or travel, will choose lingual orthodontics, because it is worn on the back of teeth and can't be seen from the outside, so it won't affect your face value, but this kind of appliance is more expensive, generally around 50 thousand yuan. Choose according to your own situation, but you must correct it. After correction, make sure that the teeth are more tidy and the face is softer. Good luck ~
