These changes may increase pathogenic organisms or their activity causing a series of oral infectious diseases such as dental caries or periodontal diseases.

这些改变可能会增加致病微生物的数量或活性，从而导致诸如齿、牙周疾病等一系列口腔感染性疾病。

So, treatment of dental caries disease depends on the level of risk, more specifically, reducing the pathogenic risk factors like antibacterial rinses to get rid of bacteria and increasing protective factors like products that mimic saliva.

所齿的治疗是由风险的低决定的，包括减少致病因子，例如用抗菌剂冲除细菌，增加防护因子，例如使用唾液类似物。

We are finding mucus is compromised in a number of diseases or conditions, including inflammatory bowel disease, cystic fibrosis, certain forms of dental cavity formation, certain forms of infertility.

我们发现，黏液在多种疾病或状况中受到损害，包括炎症性肠病、囊性纤维化、某些形式的齿形成及某些形式的不孕。

But if we keep consuming sugar and starch mindlessly, more minerals will be lost and the decay process will continue beyond repair.

但如果我们继续盲目地摄入糖和淀粉，就会失更多的矿物质，齿的过程将继续下，直到无法修复。

However, moderate consumption of red wine may enhance oral health, because it contains a mixture of organic acids that are active against oral streptococci responsible for caries development and streptococcus pyogenes responsible for pharyngitis.

不过，适量饮用红葡萄酒可能会增进口腔健康，因为红葡萄酒中含有一种有机酸混合物可有效抑制导致齿的口腔链球菌属及导致咽炎的化脓性链球菌。

And sure, eating lots of sugary food can cause cavities that don't feel great, but that wasn't some sort of insta-cavity.

当然了，吃大量的含糖食物会导致齿，这种感觉并不好，但我在讨论的并非是齿的情况。

A British company says it has developed technology that will end the need for mechanical cleaning of dental cavities.

Dentists point out that the new method is most efficient on early-stage cavities, which makes regular dental checkups essential.

牙科医生指出新方法对早期齿患者最为有效，对牙齿进行定期检查是非常重要的。

So we're checking for signs of cavities or gum inflammation.

因此，我们要检查是否有齿或牙龈发炎的迹象。

The process begins with a cleaning of the cavity. This does not require power tools.

这个过程最开始是齿洞清理，不过并不需要电动工具。

After cleaning the early-stage cavity with a method that does not require drilling, the dentist covers it with a mineral solution and applies an electrical current that is too weak for the patient to feel.

在无需进行钻孔的情况下对齿早期进行清理，牙科医生利用补矿盐进行填充，之后施加微弱电流，使病患无法感知电流的存在。

If action is taken at this point, by supplying enough minerals and Fluoride, the enamel can still repair itself and the decay can be stopped or even reversed.

如果在这时候采取行动，通过供足够的矿物质和氟化物，牙釉质仍然可自我修复，齿可停止甚至逆转。

Symptoms of dental caries include tooth pain and sensitivity, especially when chewing or drinking something that's cold or hot, or sweet.

齿的症状包括疼痛和敏感，尤在咀嚼或饮用冰、热、甜的东西时。

So a sugar-rich diet and frequent snacks can lead to dental caries while a diet with increased fibers foods and diary products help maintain a healthy balance in the oral microbiota.

If the cavity is not too deep, the experience can be unpleasant. However, if it is deep, near the nerve of the tooth, it can be very painful.

如果齿洞不是太深，这种经历只是让人不舒适。但是如果洞很深，接近牙齿神经，就会非常痛苦。
