Tooth pain after nerve extraction – what to do?

Reading time ~ 6 min. Number of readings: 82533

The viability of the tooth, in particular its sensitivity, provides the neurovascular bundle (pulp). Removal of the pulp (depulpation) is a forced measure, which is resorted to for serious indications (pulpitis, root cysts, damage to the pulp chamber due to trauma, etc.). Painful discomfort for several days after depulping is a normal reaction of tissues to the intervention. But if the tooth hurts after nerve removal and canal filling 2-3 weeks later, or if the pain occurs sharply long after endodontic treatment - this is a serious reason to consult a dentist.

Even treated teeth should be examined every year to diagnose or rule out complications at an early stage. A depulped tooth doesn't hurt, but it's like a ticking time bomb. Poor treatment of canals can provoke complications that destroy the jawbone, cause purulent processes (cysts, abscesses), lif…

牙龈微笑--矫正方案

露龈笑是上牙龈过度暴露的一种生理特征。在正常的微笑中，牙龈外露的面积为 1-2 毫米，如果面积更大，这种微笑就被称为龈笑或 "龈笑"。这种粘膜外露不属于病态，不会影响发音和咀嚼功能，也不会影响牙齿的健康。

不过，有研究称，粘膜过度暴露会导致自尊心下降和心理变化。

原因

牙龈过度暴露主要是由于上颌骨（下颌骨）的结构造成的。其过度发育导致即使是正常的上唇也显得很短，无法完全覆盖粘膜。

另一个原因是上唇过度上扬。如果口腔的环形肌肉过于强壮（医学术语为 "过度活跃"），嘴唇就会比正常情况下翘得更高。牙齿和牙龈的大小可能是正常的，但嘴唇却比正常的嘴唇高出一...

牙周病：原因、症状和治疗

牙周病是牙齿周围组织的一种萎缩性病变，它将牙齿固定在牙槽骨（牙腔）中。它伴随着牙周某些区域的萎缩、骨组织的硬化变化、骨量减少、牙龈退缩、牙颈部暴露和敏感性增加。随着病情的发展，牙槽突高度降低，牙龈关节完全被破坏，牙齿细胞的骨壁吸收，导致牙齿脱落。

该病的特点是病程缓慢，临床症状表现为牙周明显的破坏性变化。诊断的依据是临床表现和 X 光检查结果。只有牙医才能注意到牙周组织病理变化的开始。如果病人看到牙周病的症状，那么这种疾病已经持续多年了。

四环素牙：诊断和治疗方法

四环素牙--一种全身性釉质发育不全，是由于在牙齿及其雏形形成、牙齿和骨组织矿化过程中摄入四环素类抗生素所致。其特点是牙釉质颜色明显改变，结构紊乱。门牙的切缘和臼齿的咀嚼面都会着色。四环素牙的颜色从亮黄色到蓝褐色不等，颜色的深浅取决于药物、剂量和摄入时间的长短。不仅表面的珐琅质层会被染色，深层组织也会被染色，这给恢复牙齿的自然洁白造成了困难。

症状持续性不可逆转的褪色；色素沉着为灰色、黄色、棕色、褐色；整个牙冠或单个部分染色；牙釉质变薄、裂纹、碎裂；对冷、热敏感；牙齿的四环素染色不均匀，看起来像牙齿上的横向条纹...

牙周炎：原因、症状和治疗

牙周炎是一种具有炎症性质的牙周疾病，如果得不到适当的治疗，会导致牙龈交界处的破坏和牙齿脱落。牙周炎起初是牙龈发炎，表现为慢性牙龈炎。随后，病理过程影响到深层组织，导致牙周、牙槽（龋洞）和邻近颌骨的破坏。

牙齿和牙周是一个单一的功能和形态相关的系统。单个元素的损坏会破坏牙齿单元的功能，导致牙龈附着力下降、形成深龈袋、脓肿、牙龈瘘管、牙齿松动和脱落。

症状牙龈发炎；粘膜充血（发红）、肿胀、对温度刺激的反应；牙龈疼痛；不适、咀嚼时牙龈出血、口腔卫生；牙龈与牙齿脱落...

Eliners or braces – which to choose?

Technology is expanding and improving, and orthodontic systems are becoming more and more discreet and comfortable. Today, braces or eliners are used for treatment. Both technologies effectively cope with almost any orthodontic anomaly. Each has its own pros and cons. The principle of treatment methods do not differ much, the main difference between eliners and braces - in aesthetics, convenience of wearing.

What are braces?

Bracket-system - fixed orthopedic apparatus, consisting of locks with grooves (brackets), arc, which combines these locks into a single mechanism, additional elements - elastics, ligatures, through the grooves conduct the arc. The principle of operation lies in the ability of the metal arch to take the original shape. Straightening, it pulls the locks behind it, pulling the teeth to the desired position.

Whether wisdom teeth need to be removed

Wisdom teeth (eights, third molars) are the last units on each side of the tooth row. They are the last to erupt when the dentoalveolar system is fully formed. And in most cases, their appearance causes a lot of problems. Since they often do not have enough space in the row, they grow incorrectly: at an angle, sideways, horizontally, interfere with neighboring units, traumatize the mucosa of the cheeks, tongue.

Whether it is necessary to remove wisdom teeth - depends on the clinical situation. The doctor will not remove the third molars "just in case". There must be medical indications for this. The anatomy of the eights is more complex, they are the largest units in the row with a developed root system. Although they belong to the chewing group of teeth, they do not take part in the process of chewing, this function of the units is weakened or absent. The primary function of the third molars is to keep the teeth in the row from moving apart.

Zirconia dental implants: advantages and features

Until recently, medical titanium was the only material for implants. Pins made of this metal and its alloys worked well, but unfortunately were not suitable for people with allergies to certain metals. Sometimes patients refused titanium implants for aesthetic reasons. In recent times, they have been joined by adherents of holistic medicine.

Dentists have offered an alternative to the titanium rod - a zirconium implant. Although the first constructions made of ceramic appeared in the late 80s of the last century, they became widespread in the last 10-15 years. In the USA their use was approved only in 2011, in Europe - a little earlier, in 2005.

Advantages and disadvantages

Zirconium implants for teeth are hypoallergenic. This is their main advantage. If a patient develops an allergy to titanium alloy, it will not be limited to itching and redness. The pin will most likely be rejected. With a zirconium implant, there is no need to fear this. 更多信息
