TOWARDS ZERO CAVITY



PART 2: EFFECTIVE WAYS FOR PREVENTION OF DENTAL CARIES

What is the treatment for dental cavities?
1.   Standard treatment for cavities is to fill/restore the tooth.

2.   If the cavity is large and the remaining tooth may not be able to support the amount of filling material that would be needed to repair it. Then, the dentist will cover the tooth with a crown as protection.

3.   If the damage in the interior of the tooth, root canal treatment may be needed to save the tooth.

What can be done to prevent tooth decay? 
There are several things that can be done to slow down or prevent the breakdown process which leads to cavities.

Here are some useful tips:
  • Brush twice a day
  • Clean between your teeth daily by using interdental aids like floss or interdental brush to remove plaque from areas your toothbrush cannot reach

  • Rinse thoroughly, twice daily, after brushing with non-alcohol mouthwash
  • Eat a healthy diet and limit carbohydrate intake
  • Visit your dentist regularly for professional cleanings and oral examination

什么是根管治疗??

一颗健康的牙齿
一颗牙齿有一个牙冠和一条或数条牙根。牙根使牙齿固立在牙骨间。牙齿的中心是牙髓,含有神经和输送营养料的血管。
一颗病坏的牙齿
一颗病坏的牙齿,其牙髓受感染或损伤。起因主要是蛀牙,但也有损伤或牙龈造成的。

什么是根管治疗?
根管治疗是指自病坏的牙齿去除受感染或损伤的牙髓。过后把空洞的髓腔洁净,填补和密封。

根管治疗的好处
根管治疗可以保留否则要被拔除的牙齿。虽然牙髓已被除去,牙齿仍旧牢固的置于牙骨中,照常咀嚼。

根管治疗的替代法
拔牙是唯一的替代法。拔了牙之后,要镶假牙或牙桥。不然的话,邻牙会移位,造成咀嚼和洁牙的困难。这些问题又会导致牙龈病和蛀牙。

根管治疗的步骤。。。
  1. 在牙冠钻孔。
     
      2.从牙髓腔和根管除去牙髓。把根管弄干净。

      3.用中性物把根管填满以及用永久性修复物把孔道覆盖。

有时根管治疗只需一次的诊治。不过数次诊治是惯例的。


经过根管治疗的牙齿会比正常的牙齿脆弱,但是适当的修复和照顾会使受用不尽。适当照顾包括经常刷牙刮牙,适当的饮食和每六个月的定期检查。

Root canal treatment = The tooth saver?





Anatomy or sturcture of a tooth

Endo” is the Greek word for “inside” and “odont” is Greek for “tooth.” Endodontic treatment treats the inside of the tooth.
At the center of a tooth is a hollow area that houses of soft tissue, known as pulp or nerve. This hollow area contains a relatively wide space in the coronal portion of the tooth called the pulp chamber. This chamber is connected to the tip of the root via narrow canal(s); hence, the term "root canal."





A tooth's nerve and pulp can become irritated, and infected because of deep decay, large fillings, a crack or chip in the tooth, or trauma to the face. If the infected or dead pulp untreated, pus can build up at the root tip in the jawbone, forming an abscess which can destroy the bone surrounding the tooth and cause unbearable pain.
 

What is a Root Canal Treatment?
Root canal treatment, also known as endodontic treatment, is the process removal of the tooth pulp, a small, thread-like tissue in the center of the tooth. Once the damaged, diseased or dead pulp is removed, the remaining space is cleaned, shaped and filled. The root canal is sealed off.


What Are the Signs That a Root Canal Treatment Is Needed?
 You may need a root canal treatment if,

  • Severe toothache pain while chewing
  • Prolonged sensitivity/pain to heat or cold  
      temparature
  • Discoloration/yellowish of the           
          tooth                       
  • Swelling and tenderness in the nearby gums
  • A persistent or recurring pimple on the gums
  • Sometimes no symptoms are present




What are the procedures of root canal treatment?

From left to right: images of procedure of root canal treatment


  • Decay is removed to expose the nerve tissues and access into the canal.
  • The pulpal tissue is removed with special files
  • The canals are cleaned, shaped to allow filling of the root canal system
  • The canals are filled and restored with temporary filling

Will the tooth need any special care or additional treatment after endodontic treatment?
You should not chew or bite on the treated tooth until you have had it restored by your dentist. The unrestored tooth is susceptible to fracture, so you should see your dentist for a full restoration as soon as possible. 

A post is needed if tooth structure not sufficient to support the crown
A crown or other restoration placed on the tooth to protect and restore it to full function.                                                          

Full restoration of root treated tooth



Otherwise, you need only practice good oral hygiene, including brushing, flossing, and regular checkups and cleanings.


Is a root canal treatment painful?
Pain, the fear of pain is the main reason of us delay our visit to the dentist for dental check up. Finally end up suffering much more pain than those visiting their dentist early for proper treatment.
Endodontic treatment can relieve the toothaches caused by pulp inflammation or infection. With modern techniques and anesthetics, most patients report that they are comfortable during the procedure. 


However, the tooth may feel sensitive for the first few days following the completion of a root canal due to natural tissue inflammation, especially if there was pain or infection before the procedure.



Is it worth to save instead of extracting it?

Extraction may be a quicker and cheaper alternative, but seldom is it in the best interest of the patient. Most of  times, an extraction leads to subsequent problems such as general instability of the whole dental arch because
the adjacent teeth will over growing and shifting.

Endodontic treatment with full restoration usually cheaper than a bridge or an implant placement following extraction. It is a cost-effective way to treat teeth with damaged pulp. 


Teeth with diseased or injured pulps were removed at years ago. Today, root 
canal treatment enable keep the teeth that would otherwise be lost. 
Most endodontically treated teeth last as other natural teeth as far as oral health care is concerned.




"Nothing, not even the most advanced bridges and implants, can truly replace your natural tooth"
Save your natural tooth should always be your first choice

牙齿刺痛的原因





牙齿刺痛的原因

牙齿刺痛是牙髓的神经受到刺激所引致。常见原因: 
蛀牙洞内的细菌引起牙髓发炎,刺激牙髓神经。
象牙质内满布管道,如果这些管道因牙龈萎缩或因牙齿表面受损(例如:被牙 
刷刷蚀又或被酸性食物侵蚀)而外露,冷、热、甜、酸的食物便会透过这些管
道刺激牙髓神经。与此同时,牙齿表面的牙菌膜的毒素亦有可能透过外露的象 牙质,刺激牙髓神经。
  • 牙齿崩裂
牙齿崩裂导致象牙质或牙髓外露令牙髓神经受到外界刺激。
 
牙龈疼痛的原因
压龈疼痛是牙周组织发炎所引致,常见原因:
  •  蛀牙
严重的蛀牙令牙髓坏死,细菌在牙髓内滋生,并经由牙根管感染牙周组织,引致发炎及出现脓疮
  • 牙周病
牙菌膜的毒素引致牙周组织发炎。
  •  智慧齿冠周炎
由於智慧齿的牙冠与覆盖它的牙龈之间容易积藏食物渣滓和细菌,导致牙周组织发炎

处理方法
应尽快见牙科医生,找出原因,对症下药:
  •   蛀牙
治疗方法: 牙髓治疗 补牙 人造牙冠
  •  牙周病
治疗方法: 洗牙 牙根刮治 牙周手术
  •  智慧齿冠周炎
治疗方法: 洗牙 服用抗生素
  •  象牙质外露
治疗方法: 涂搽高浓度氟化物 补牙 人造牙冠
  • 牙齿崩裂
治疗方法: 拔牙 补牙 人造牙冠 牙髓治疗
