根管治疗后的牙齿能维持多久

您好,根管治疗后没有做牙套保护起来的话,一般两三年左右可能出现牙齿开裂,再次保留的可能性较小.做个烤瓷牙套将牙齿保护起来,大概在一二十年左右,具体也要看平时保护和假牙跟牙龈的密合度

祝您健康!

怎样保持牙齿的健康?

牙体包括牙釉质、牙本质、牙骨质三种硬组织和容纳牙髓的髓腔(如下图)。如果日常生活中不注重对牙齿的保健很可能导致蛀牙(龋齿)的发生。

口腔内的乳酸杆菌使糖类酵解产酸,这些酸穿透牙釉质表面而使牙齿的矿物质——羟基磷灰石Ca5(PO4)3OH溶解,产生空洞,称为龋齿。由于细菌在牙齿表面形成一层黏附膜——齿斑(或称菌斑),这些有机酸能长时间地跟牙齿表面密切接触,使羟基磷灰石溶解,原理是:Ca5(PO4)3OH + 4H+→ 5Ca2++ 3HPO42-+ H2O。若龋洞不断加深,波及牙髓的神经,则引起剧痛。龋齿是细菌性疾病,因此它可继发牙髓炎等。

如何预防龋齿?首先要保持口腔清洁,最有效的办法是刷牙漱口。牙医建议,刷牙要在吃过饭的3分钟内进行。刷牙可清除口中的大部分细菌。应做到早晚各刷一次,饭后漱口。晚上睡觉前,刷牙尤重要,因为它能清除当日三餐积存于牙齿上的食物残渣污垢。

“牙膏是刷牙的辅助用品,具有摩擦和祛除菌斑、清洁抛光牙面、清爽口腔的作用。”牙科大夫说。目前我国的牙膏分为普通牙膏、氟化物牙膏和药物牙膏三大类。无论哪种牙膏,主要成分基本相同。“牙膏在口内停留时间短,一些特效牙膏难以在短时间内发挥药效。若牙齿健康,选用普通牙膏即可。”

其次,增强牙齿的抗龋性。其原理是:Ca5(PO4)3OH + F-→ Ca5(PO4)3F + OH-,通过增加牙齿中的氟元素,使羟基磷灰石转化成氟磷灰石,则更能抵抗酸的侵蚀。此外,氟离子还能抑制口腔细菌产酸。目前,使用含氟牙膏是较普遍的方法,其中添入牙膏预防龋齿的氟化物有氟化钠和氟化锶等。很多研究证明,氟化物有毒害作用,过量的氟不但会造成牙齿单薄,更会降低骨头的硬度。氟已被世界卫生组织认定是带有潜在毒性的微量元素。因此使用含氟牙膏需注意如下事宜:1、高氟地区人们不宜用含氟牙膏;2、含氟牙膏不适合宝宝用,儿童需注意不能摄入过量;3、用含氟牙膏刷牙后,必须将牙缝中残留的牙膏彻底清除干净,不能将牙膏和漱口水吞入腹中。

人的正常牙能用到多少岁

你好,一般如果注重牙齿清洁与牙齿健康,有一个良好的口腔卫生情况,我们至少到七八十岁有一口坚固的牙齿也是没有问题的。

门牙做根管治疗后牙齿能保持多久呢?正常情况下

1.必须做根管治疗,不然根尖炎症无法控制。

2.由于牙齿是受过外伤的,有的牙会在一段时间后发生外吸收内吸收。但是不是每个外伤的牙都会。总之外伤后的牙愈后比其他牙齿要差。但是维持几年没问题。就算发生吸收也可以在进行治疗控制。

3.如果牙体组织够的话不需要打桩。打桩是为了增加牙冠的固位。

4.同2.

5.你门牙至少要金属烤瓷吧,全金属太影响美观。金属烤瓷冠有镍镉的和金合金的。建议金合金烤瓷冠。镍镉将来会引起牙龈变色的。但是美观上还是全瓷最佳。

50岁还能矫正牙齿效果能够保持多久啊?

p牙齿矫正是没有年龄限制的。决定能否接受正畸的关键因素不是年龄大小,而是牙周的健康状况。/pp一个爱护自己牙齿、定期进行检查的人,到50岁了其牙周状况可能与年轻人也无明显差别,同样具备正畸条件,也就是说可以做矫正的。/pp不过有一个比较现实的问题就是年纪越大,矫正牙齿的效果也就越慢。如果晚上出现了磨牙,很有可能会使牙齿咬合面不平所引起的,可以及时到医院的牙科诊所去做一下检查,可以通过矫正或者是通过医生的治疗,这样就可以改善出现磨牙的现象。/pp另外很多人到50岁的年龄,身体钙质的流失,牙槽骨的条件也并不好,这种情况是不建议正畸的,因为正畸后的效果也不一定理想。/pp如果50岁了做了正畸,那在维持效果上是只要牙齿不掉都是完全不用担心的,牙齿矫正后牙齿的排列更加整齐,只要牙齿不发生外力因素和不可抗因素,整体效果都不会受到威胁。/pp!--5f39ae17-8c62-4a45-bc43-b32064c9388a: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
