I've noticed that my daughter's teeth aren't growing straight. Her teeth are too big. There doesn't seem to be enough space for them.
我發現我女兒的牙齒長的不正，牙齒也太大了，好像空隙不好。
How old is your daughter?
你女兒有多大了？
She's eight years old and I'm very worried that she's going to have crowded (crooked) teeth like mine.
她八歲，我擔心她會跟我一樣長寄生齒。
Yes, malocclusion is very often related to heredity.
對的， 牙合不正通常與遺傳有關。
What's malocclusion?
錯頜畸形是怎么回是？
Occlusion refers to the way that the teeth fit together, and their position in the mouth. The word malocclusion means that the teeth don't fit together properly.
咬合指的是上，下牙排牙齒合到一起時位置合適，錯頜畸形指的是咬合位置不合適。
Make an appointment for your daughter so that I can examine her and refer her to an orthodontist if I think that it's necessary.
給你女兒預約個時間，這樣我可以給她檢查，必要時我可以給他介紹一位正畸齒科醫生。
Are there other causes for malocclusion?
錯頜畸形還有別的什么別的原因嗎？
Malocclusion can be related to habits such as thumb sucking or premature loss of the deciduous (milk, baby) teeth.
錯頜畸形與一些習慣如允吸大拇指乳牙過早脫落有關。
It's very important to make a space maintainer if the second deciduous molar is lost too soon.
假如第二顆乳牙過早脫落，那摸裝上間隙保持器是件要緊的事。
This will help to prevent a malocclusion from developing.
這樣有助于防止錯頜畸形繼續發展。
Most of the time, a malocclusion is caused by the fact that the teeth are too large in relation to the size of the jaws
在大多數情況下，錯頜畸形是由于牙齒比起上，下頜的大小來說大了一些。
Can you extract the teeth, Doctor?
拔了牙不行嗎？
Extracting deciduous teeth may help temporarily, but it's usually necessary to remove some of the adult (permanent) teeth to make enough space for the remaining teeth. Then orthodontic appliances (braces) are used to move the teeth into a normal position.
拔掉乳呀可能暫時有幫助，但是通常有時需要拔掉幾顆恒牙，讓留下來的牙齒有足夠的空間，然后用絞型裝置將牙齒移到正確的位置上。
