Hello, I'm a fan of General Electric .. Her left jaw has shrunk, which makes the teeth of the upper and lower jaws unable to bite, resulting in air leakage when speaking, instead of shortening the lingual frenum commonly known as "tendon". According to the doctor's advice, it is not suitable for surgical correction until the body of 2 1 year old stops developing. However, she said that due to the high risk of surgery and the situation has not deteriorated, she will not undergo surgery for the time being. So it's weird to laugh and talk.
