Usually, a healthy tooth is divided into three parts: tooth hard tissue, tooth soft tissue and periodontal tissue.
First of all, the hard tissue parts of teeth are mostly enamel (also called enamel), dentin and cementum from outside to inside;
Next, you care more. The middle of the tooth is where the soft tissue of the tooth is located. Our dental pulp is wrapped inside, and the whole body is covered with blood vessels and nerve tissue.
Finally, here is the Department of Periodontal Histology. Include gingiva, periodontal ligament and alveolar bone.
This picture also shows our common dental diseases, including pit and fissure caries, lateral caries and pulp caries.
Knowing about diseases, we also need to know how these diseases usually occur and spread, hoping to remind us how to do well in protection. Generally, the dental caries in pits and gullies are about six years old. It's a permanent molar, but it's easy to get dental caries because of young age and insufficient nursing. However, at present, WHO will organize schools to help children seal pits and seams for free. Parents can pay attention to it. Of course, people who don't do pit and fissure sealing are more prone to dental caries. It is good to find it early and check it early.
Lateral caries are mostly caused by trauma, wear or dental plaque. For chronic dental caries caused by dental calculus and dental plaque, after dental calculus is found, it can be removed by washing teeth. The benefits of tooth washing can not only remove dental plaque and avoid dental caries, but also protect gums and prevent periodontitis. This way, eating apples will not bleed, and brushing your teeth will not bleed.
Finally, if the pulp is diseased, it means that the teeth have been decayed for a long time, which is delayed by improper nursing and treatment. This will endanger the retention of teeth. Most of them need to consider root canal therapy, or measures such as tooth extraction and filling.
The above is a preliminary overview, and the specific condition must be diagnosed according to the clinic.
