A little vulnerability never hurt anyone, but there#39;s one part of you that can be too sensitive—your teeth. Here#39;s how to toughen up your chompers.一点点敏感脆弱或许不会伤害任何人,但是你身体的一个部位太敏感了却不太好——你的牙齿。采纳以下建议,坚固你的牙齿。You Will Need你需要A soft-bristled toothbrush软毛牙刷Desensitizing toothpaste脱敏牙膏Steps步骤Step 1 Avoid acid amp;amp; carbonation1.避免酸性和加糖食品Avoid acidic foods and beverages and carbonated drinks.避免酸性食物和饮料,不要喝加糖饮料。Step 2 Wait before brushing2.进食后不要立即刷牙Always wait at least 30 minutes after eating before brushing your teeth.吃东西后至少等30分钟再刷牙。Step 3 Use right brush3.使用正确的牙刷Brush with a soft-bristled toothbrush and use desensitizing toothpaste containing fluoride and either potassium nitrate or strontium chloride. Both help block the transmission of sensations from the tooth to the nerve.用软毛牙刷和含有氟化物,硝酸钾或氯化锶的脱敏牙膏来刷牙。这两种成份都可以阻止敏感从牙齿传递到神经。Overzealous brushing, particularly with a hard-bristled toothbrush, can actually lead to hypersensitive teeth—so use a soft-bristled brush and be thorough but not too aggressive.过度刷牙,尤其是用硬毛牙刷刷牙会导致牙齿高度敏感——所以,使用软毛牙刷来彻底刷牙,但是不要太用力。Step 4 Don#39;t grind teeth4.不要磨牙Don#39;t grind your teeth, which can cause increased sensitivity.不要磨牙,否则会导致牙齿更加敏感。If you grind your teeth in your sleep, wearing a mouth guard can help protect your enamel.如果你在睡觉的时候磨牙,戴护口器可以保护牙釉质。Step 5 Visit a dentist5.看牙医If taking these steps doesn#39;t help, visit a dentist. There are several procedures that might help you.如果采取以上措施都没有效果,还是去看牙医吧。牙医会采取一些治疗来帮助你。Sensitive teeth are usually caused when tooth enamel wears down or your gums recede, exposing tiny tubes that access nerves and cells inside your teeth.敏感牙齿通常是由于牙釉质脱落或牙龈退化造成的,导致连接牙齿内部的神经和细胞的微小血管暴露出来。 /201501/357171
