清晨冷水刷牙时一阵刺痛?
吃酸冷的食物突然牙齿酸软?
寒冷的早晨深呼吸牙齿刺痛?
如果有这些症状，您的牙齿可能属于“敏感性牙齿”
(学名叫做牙本质敏感)
Do you feel pricking when brushing teeth with cold water?
Do you feel aching when having sour and cold food?
Do you feel stabbing pain when breathing in cold morning?
If you have these symptoms, your teeth may belong to sensitive teeth.
(scientific name: dentine hypersensitivity)
“
牙本质
牙本质由许多小管组成，它介于牙釉质和牙髓之间，内含神经纤维和液体。当外界刺激时，牙本质小管内的液体流动加速，从而刺激神经末梢产生疼痛。
Dentine composes of many small tubes. It is between enamel and dental pulp, including nerve fiber and liquid. When with external stimulus, the liquid flow in it will widen and trigger pain by stimulating nerve endings.
通常牙周退缩、牙齿磨损后，外界刺激更容易通过开放的牙本质小管到达牙髓神经而引发牙齿刺痛感，所以牙齿敏感是多种口腔疾病的一种临床表现，并不是一种疾病。
Usually, when the phenomenon of periodontal recession and tooth wear happens, the external stimulus is easy to touch dental pulp nerve in open dentine tube and produce pricking. Therefore, tooth hypersensitivity is one kind of clinical performance of many oral diseases, which is not a kind of disease.

牙齿敏感的真相
真相一：牙龈萎缩
牙齿根面有无数小管直通牙髓神经，一旦牙龈萎缩，牙齿失去了牙龈屏障，刺激可毫无阻碍地直接作用于牙髓神经，容易引起敏感疼痛等症状。
The tooth root surface has many small tubes, which is straight in dental pulp nerve. As long as the teeth recede, it loses the gingival protective screen and the stimulus will stimulate dental pulp directly. So it will trigger sensitive pain and other symptoms.
牙龈萎缩这可能是由于：
1、牙周炎导致牙龈退缩，暴露根面；
2、刷牙力度太大，刷毛太硬，引起牙龈退缩，牙根面暴露。
1、Periodontitis will lead to recessing gingiva and expose tooth root；
2、Brush teeth with strong force. The hard bristle will cause gingival recession and exposed tooth root;
一天口腔专家建议：
1、选择软毛牙刷，控制刷牙力度；若无法控制刷牙力度，建议使用电动牙刷；
2、定期拜访专业牙科诊所，进行洁牙及牙周治疗。
1、Choose soft-bristle brush and control the brushing force; if you cannot control it, you should choose electronic toothbrush.
2、Regular visit to professional dental clinics and perform teeth-cleaning and

真相二：牙冠釉质磨损
牙冠表面釉质磨损，导致脆弱牙本质暴露。牙本质结构与牙根类似，也有无数小管直通牙髓神经，温度或机械刺激都会刺激神经。
紧咬牙或磨牙、刷牙时横刷力量过大，距离过长、频繁使用含酸性物质的漱口水、过量食用酸性物质，这些都可导致釉质腐蚀。
The enamel in tooth crown suffer wearing, which causes the exposed fragile dentine. The structure of dentine is similar to tooth root. There are many small tubes straight in dental pulp. The temperature or mechanical stimulation will irritate nerves.
Clenching teech or grinding teeth,transverse brushing with too much force,long distance,use acid mouth wash frequently,have too much acid food can all lead to corroded enamel.
一天口腔专家建议：
1、佩戴咬合垫，减少因磨牙或紧咬牙引起的釉质磨损；
2、掌握正确的刷牙方法，尽量竖刷；
3、咨询牙医，更换中性的口喷用品；
4、食用酸性物质后，用清水漱口。
1、Wear occlusal pad. Reduce the enamel wear due to grinding teeth or clenching teeth;
2、Use right brushing method. The vertical brushing is recommended;
3、Consult dentists and change neutral oral spray products;
4、Rinsing mouth after having acid food.

真相三：牙齿龋坏
龋坏是渐进性破坏牙齿釉质、牙本质的过程，破坏深度越靠近牙髓神经，敏感症状越明显。吃冷、热、酸、甜食品触碰到龋坏处，极易引发敏感疼痛。
The decay of teeth enamel and dentine happens gradually. The closer the destructive dept to dental pulp, the more evident the sensitive symptom is. Having cold, hot, sour, sweet food is easy to touch the decayed part and triggers sensitive pain.
一天口腔专家建议：
保持良好的口腔卫生，合理饮食，有规律地检查牙齿。一旦发现龋坏，应立即就诊。
Keep healthy oral hygiene with reasonable diet and detect teeth regularly. As long as the decayed teeth appear, patients should visit dentists instantly.
真相四：牙裂痕
咀嚼坚硬的食物等可以导致牙隐裂。虽然牙体完整，但当咀嚼时，摩擦力促使裂纹两侧的组织产生相对运动，机械和摩擦产生的热都可能刺激牙髓神经，引起疼痛。另外，隐裂纹可能残留细菌，导致牙髓感染，引起剧烈疼痛。
Chewing hard food will cause cracked tooth. Though the tooth is complete, the friction will make the bilateral crack tissue move relatively. The mechanism and friction may both irritate dental pulp and trigger pain.
Besides, hidden cracks may contain bacteria, causing dental pulp infection and causing fierce pain.
一天口腔专家建议：
一旦发现有牙齿隐裂的情况，要及时就医，防止对牙齿的“二次伤害”。因为，牙隐裂初期还可通过补牙、根管治疗、做牙冠等保住牙齿。如果牙齿完全裂开，那么只能通过拔牙解决。
As long as the cracked tooth appears, patients should come to hospital in time, preventing the secondary damage to teeth. Because cracked tooth can keep tooth by dental filling, canal therapy, tooth crown, etc. If the tooth cracks completely, it can only be treated by extraction.
一天口腔权威专家温馨提示 Tips
牙齿敏感看着是小事，但一味的挺着情况反而会更严重。俗话说的好，牙好胃口就好，所以，别再“一忍而过”啦，早发现早治疗。
Tooth sensitivity may seem not serious, but the situation will be worse with blind holding. As the saying goes, good appetite from good teeth. Therefore, do not stand it. Early discovery brings early treatment.
