More and more parents of children are accepting to beautify their children’s teeth at school age, and some parents are getting anxiety because of their children’s uneven teeth, so I have to say that Chinese parents’ concern for their children’s teeth is getting more and more in line with international standards. However, what depresses parents is that their attention is not recognized by the doctor. Parents often respond to the situation after the visit, “We have seen it before and the doctor told us to wait until we are 12 years old, it is still early? Parents are often high on this classic line from the doctor: they feel they haven’t missed the best time for correction! The truth is always the opposite of what you want, and this patient I saw two days ago in the clinic I think is simply unfortunate to the extreme. The father felt that his child was very slow to eat and that his mouth was a bit protruding, which affected his appearance. Clinical examination revealed that the upper lip was shortened, the upper alveolus was too high, the lip was open and the teeth were exposed, the lower jaw was receding, and the upper teeth were covering the lower lip. The parents were advised to take a panoramic film: all the 2 tiger teeth had fallen into the position of the incisors, and not only that, the roots of the second incisor next to the teeth had been resorbed, and the cysts of the buried teeth appeared on the other side. Such symptoms 12 years old orthodontic is obviously ruined the happiness of the child’s life! Such a tragedy, I hope not in my patients, no matter how busy and tired and hard, the first initial consultation must be carefully examined by the doctor, do not be 2 words to send off! Early judgment of the buried teeth if they can not be corrected out, early extraction at least will not cause the symptoms of cysts.
