Hypersensitive Teeth
牙齒過敏
Good morning, Doctor Smith.
早安，史密斯先生。
I'm happy that I could get an appointment with you so quickly.
能這么快跟您預約好，我真高興。
Many of my teeth have become very sensitive at the gumline.
我的許多牙齒的牙齦邊緣變得十分敏感。
This is a problem I see in many patients.
我有許多病人都有這個問題。
When the gum has receded from a tooth, the root surface becomes exposed.
當牙齦萎縮下來后，牙根的外表就暴露在外面了，
The root isn't covered with tooth enamel.
牙根是沒有牙釉質(zhì)蓋住的。
Is that the cause of the pain?
這就是造成痛的原因。
Yes, that's why it might be sensitive to cold, heat, sweet foods or to the touch.
是的，這就是對冷熱，甜東西和碰到它時就會感到過敏的原因。
The degree of sensitivity will change from time to time.
敏感的程度時不時有所改變。
Sometimes the pain will disappear and come back again at a later time.
有時不疼，有些時候又疼了。
If the tooth isn't kept clean by toothbrushing and dental flossing, the pain will be more severe.
假如沒有利用刷牙或牙線把牙齒保持清潔，那么會疼得更厲害。
However, sometimes toothbrushing is painful, Doctor.
醫(yī)生，我有時是刷牙感到很疼。
Please brush your teeth very thoroughly in spite of the discomfort.
盡管不舒服但是刷牙仍然要刷的很透徹。
That will help to reduce the pain.
這樣可以少疼一些。
Try to brush without toothpaste for three days.
先試一試不用牙膏刷牙三天。
Try using a different brand of toothpaste.
試一試用別的牌子的牙膏。
Don't use chemical mouthwash.
不要用化學漱口藥。
Teeth may also be sensitive because of irritation to the tooth pulp from habits of clenching (clamping) or grinding.
牙齒過敏也是可能因為有藥咬牙或磨牙的習慣而是的牙齒根管的受到刺激。
If you find yourself grinding or clenching your teeth when you're awake, please stop doing it.
你醒來時發(fā)現(xiàn)你自己磨牙或咬牙，那么就不要在磨牙咬牙了。
Incorrect brushing causes gum recession and abrasion (wearing away of the soft root surface at the gum line).
刷牙刷得不正確會造成牙齦根莖萎縮和磨損。
All of this can prevent gum recession, Doctor?
醫(yī)生，你所說的能預防牙齦萎縮嗎？
Yes, be careful to brush your teeth correctly to lessen the chances of causing gum recession.
是的， 小心刷牙，要刷的正確以便減少造成牙齦萎縮的機會。
Furthermore, don't use toothpastes or tooth powders that advertise greater "whitening" ability.
還有，不要用那些廣告上所說的“增白”能力很強的牙膏或牙粉。
Sometimes they contain rough abrasives that cause increased abrasion of the teeth at the gum line.
這些牙膏或牙粉含有粗槽的磨牙劑，使用齦線上的牙齒的磨損增加。
Do you recommend endodontic treatment for this?
你是不是主張采用牙根管療法？
No, I don't recommend endodontic treatment for this condition.
不，在這種情況下我不介紹你采用牙根管治療法。
I don't place fillings in these teeth unless the abrasion is very deep.
除非這些牙齒磨損太深。
Both of these procedures sacrifice normal, healthy dental tissues.
否則我是不給補上的/這些療法都會使正常的和健康的牙組織受到損害。
