In order to better understand the problems of broken teeth, we must investigate the causes that lead to them. The tooth is mainly made up of 3 layers: enamel, dentin and pulp. The outer layer is called enamel, which is the hardest substance in the human body and is stronger than the bones that make up the skeleton. Enamel is the visible, white, protective layer around a tooth. The part above the gums that appears when we smile is called the crown. Under the enamel is a soft tissue called dentin, which forms a major part of the tooth structure and plays a protective role that protects the core of the tooth, which consists of blood vessels and nerves. In fact, the pulp and dentin hold the roots of the teeth firmly in the jaw.
The lower part of the tooth consists of the roots in the gums and jaw, which are not covered with enamel, but with another layer called cementum. Mortar is similar to enamel but is slightly softer. The surface layer of tooth enamel is vulnerable to injuries and fractures.
When a tooth is chipped, broken or cracked, it mainly affects the outer layer, the enamel. However, in certain circumstances, damage and fractures may also involve the dentin and pulp layers. For example, the face and teeth may be severely damaged and injured as part of the accident. The inner layers of the tooth are usually not affected by the fracture, but if the broken tooth is not repaired in time, the pulp and root of the tooth may become irritated or infected.
