The main problem of removable onlays - they provoke the development of caries. Using universal plates, it is impossible to ensure a tight fit to the gum. Bits of food get stuck under the edges, providing bacteria with a breeding ground. It is difficult to notice decay, because it is masked by the onlay. The tooth can rot away completely while attention is paid to it.

Advertising claims: If you buy veneers from a drugstore, you can avoid spending money on expensive preparatory procedures. But such procedures are necessary for dental problems. Plaque needs to be removed, decay needs to be treated, otherwise you can quickly be left without teeth. Removable onlays mask missing teethThat's right, you can't see the hole. There's another problem. When there are missing teeth, the neighbors lean toward the void, and the antagonist tooth (the one opposite) …

牙龈炎

牙龈发炎不影响韧带，也不破坏牙槽骨，牙科术语称之为牙龈炎。这种疾病的治疗并不困难，但如果忽视治疗，炎症就会转移到韧带，并开始破坏牙槽骨。这就是牙周炎--牙龈炎的主要并发症。因此，了解这种疾病的症状和体征非常重要，以便及时采取措施，预防并发症。

发病原因

牙龈的炎症过程会引发细菌。每次进餐后，牙釉质上都会覆盖一层微薄膜--绒毛膜。与光滑的牙釉质不同，牙釉质膜是多孔的。细菌开始在薄膜上定居。其中一些会被唾液冲洗掉，然后用牙刷刷掉。但牙刷不可能完全清除牙菌斑。唾液中的钙和其他一些物质会渗透牙菌斑并使其矿化。越来越多的细菌在牙菌斑上定居...

如何正确刷牙

牙科医生总是不厌其烦地强调正确刷牙和定期刷牙的重要性。每个人的口腔中都生活着大量的细菌。人体中最活跃的液体--唾液可以中和它们的作用，但它本身并不能消灭生物威胁。这时，刷牙就能起到拯救作用。

我们刷牙是为了清除牙齿珐琅质上的主要敌人--细菌生物膜（牙菌斑）。生物膜会在每餐后沉积在牙齿上。粘稠的食物残渣（主要是碳水化合物和糖）有助于生物膜的形成。细菌一层一层地堆积在牙齿表面，产生酸性物质。

这些酸性物质会逐渐侵蚀牙釉质，并渗入牙齿。最常见的牙科疾病--蛀牙就是这样产生的。

如果不清除牙菌斑，它就会堆积、变硬，成为牙垢。然后，它会进入牙龈下，导致牙齿周围的组织发炎。这就是牙周炎，第二大最常见的口腔疾病。更多信息

Pericoronitis

For most people, teething goes without complications. But sometimes a tooth cannot fully erupt. It is hindered by thick mucosa or incorrect positioning. This is most often observed when erupting third molars. The mucosa covers the crown, food clogs under it, bacterial growth begins, which leads to inflammation - pericoronitis of the wisdom tooth. Lower "eights" are the most prone to such inflammation. There is not enough space on the lower jaw, the teeth begin to grow incorrectly, traumatizing the surrounding tissues. Theoretically, the disease can affect other teeth. but such pathology is rare.

原因

The inflammatory process is provoked by bacteria. When the tooth has not fully erupted, its part is still covered by a layer of mucosa - the hood. Under it, a moist, dark environment is formed, where food residues constantly get in. All this contributes to the rapid growth of bacterial flora and the accumulation of plaque. In turn, this leads to an inflammatory pr…

牙齿脓肿

牙龈发红、肿胀、疼痛--这些都是牙齿脓肿的典型症状，这是一种形成脓液的炎症过程。脓液积聚在牙洞中，就像一个小袋，会导致牙龈肿胀。在人们那里，这被称为 "脓肿"。

化脓性炎症可导致严重后果，因此，如果牙龈肿胀，不能自行处理。牙科会确定脓肿的原因并进行具体治疗。

牙齿化脓性脓肿--发生原因

在免疫力下降的情况下，由于牙齿外伤或感染性疾病，病原体会侵入牙齿周围的组织（牙周）。对此，身体会产生特殊的细胞--中性粒细胞。它们能中和病原体，但自身也会死亡。脓液是死细胞、被破坏的细菌蛋白质和中性粒细胞的残留物。

在牙科中，根据脓肿发生的原因，可将其分为三种类型：

根尖周在根尖处形成一个脓包...

Implant life span

Implantation is the replacement of a natural tooth with an artificial root, an implant. It is the only way to restore a tooth row that fulfills all the functions of natural teeth. Such treatment is expensive, so many patients are concerned with the question: what is the service life of dental implants?

There is no unambiguous answer, because the duration of use is influenced by a lot of factors. First of all, it should be understood that an implant is a product that consists of several parts. A titanium post is screwed into the gum, where it overgrows bone tissue and acts as a tooth root. The abutment is a transitional piece. It connects the post and the crown, the visible part of the tooth.

It should be borne in mind that the placement of a crown is not implantation, but prosthetics. The duration of use of crowns depends on the material, but in general, it is much shorter than that of an implant. For plastic - 2-3 years, metal-ceramic - 6-7 year…
