牙髓治疗(根管治疗)

牙髓治疗是处理牙髓以及牙根尽头周围组织的牙科领域。牙髓(包含神经和其他软组织)可能因为深度腐烂致病,或者牙齿在事故中遭到撞击、破裂或断裂时受伤,牙髓通常无法自己修复。如果牙髓发炎和/或感染,需要进行根管治疗。

我们提供的牙髓治疗服务包括:盖髓、根管治疗或复治、根管外科、漂白无髓变色牙、治疗牙齿外伤、诊断并治疗牙疼。

Root Canal Treatment

[wpspoiler name=”Why Root Canal Treatment?” style=”wpui-green”]
  • In the centre of every healthy tooth is the Pulp which contains the nerves and blood vessels that keep the tooth alive.
  • Not all cavities can be solved by justa filling, if the decay or pre-existing damage is too deep; the pulp at the centre can become infected.
  • Over time, the infection can travel down the root to cause damage around the root.
  • Once the pulp is injured, the tooth starts to die; this can cause pain – a toothache.
  • Other causes of pulp injury include very deep fillings, trauma, cracked tooth and gum disease.

  • Once the injury or damage is bad enough to affect the pulp, the only other option is Dental Extraction.
  • Dental Extraction causes many other problems affecting chewing and speech. It also increases risk of decay and gumdisease.
  • Root Canal Treatment is the best choice to save the tooth.
[/wpspoiler][wpspoiler name=”What are the steps in Root Canal Treatment?” style=”wpui-green”]
  • An opening is made at the top of the tooth.Using this opening, the damaged pulp tissue is removed from the pulp chamber and root canals.
  • The canals are thoroughly cleaned and disinfected.Sometimes medication is placed in the canals and the opening is closed with a temporary filling until the next appointment.
  • After the canals are flushed clean and dried, they are sealed with an inert material. The opening in the tooth is also sealed with a permanent filling usually called the core. If the tooth is too badly damage, a post is also inserted to support the core.
  • In order to better protect the tooth after Root Canal Treatment is completed, a Crown should be placed on the tooth.

[/wpspoiler][wpspoiler name=”Anything else I need to know?” style=”wpui-green”]
  • The cost and the number of visits required depend on which tooth and the degree of difficulty. Generally, Root Canal Treatment for the front teeth is easier, whereas the back teeth (molars) are more complicated and cost more.
  • X-rays are also needed during Root Canal Treatment.
  • After Root Canal Treatment, the teeth tend to be more brittle and there is a risk of the tooth cracking if a Crown is not done.

有关牙髓治疗的常见问题

  1. 牙髓治疗有什么好处?

    牙髓治疗可以挽救采用其他方法可能需要拔掉的牙齿。如有可能,最好不要拔掉您的天然牙齿。当然,偶尔也会有无法挽救的牙齿。牙髓治疗仅在可以到达根管且足够清洁及密封的情况下进行。牙齿还必须有足够的骨头支持。

  2. 需要就诊多少次?

    通常需要就诊两至三次。有时仅一次治疗即可完成。

  3. 治疗后的牙齿能保持多长时间的健康状况?

    正确的修复和牙科护理(例如正确地刷牙和用牙线进行清洁),以及定期进行牙科检查,可能会使治疗后的牙齿一生都健康。在完成牙髓治疗之后,您的牙医通常会建议进行修复,比如戴上牙冠,以保护牙齿将来免遭折断。

  4. 牙髓治疗过程疼吗?

    牙髓治疗不会引起疼痛;事实上反而会减缓疼痛。如果您牙疼得很厉害,多半是由于牙齿中的组织遭到了损坏。牙髓治疗去除了牙齿这种损坏了的组织,因此可以减缓您所感到的疼痛。

  5. 治疗过后会有疼痛的感觉吗?

    清洁根管可能会引起一点敏感,但吃一些止痛药可以缓解这种不适感。如果持续疼痛,或者疼得很厉害,请给您的牙医打电话。

  6. 牙髓治疗会失败吗?

    牙髓治疗的成功率一般高达90%。但如果出现以下情况,则可能会失败:

    • 受影响的牙齿开始腐烂;
    • 牙体修复失败;
    • 牙齿断裂。
