Knowing these different parts of your tooth’s anatomy can help you have a better understanding of proper dental hygiene and how to get it done. If you are experiencing tooth pain or notice a difference in your teeth, contact us for an appointment.
Crown
The term crown is used to describe everything you see above your gum line. The enamel, the dentin, and the pulp are not all visible but make up the layers of the crown. Around your tooth, you will see the gums, and the bone extending below this forms the root of your tooth. The shape of your crown determines the function of the tooth. Molars, canines, and incisors all have different functions based on shape.
Enamel
The enamel is the tough outer shell of your tooth. It protects the internal structures from damage and consists of calcium phosphate minerals that are the hardest found on the body. Even though this is the hardest tissue, it can easily be damaged and not repaired since it is not living. The enamel can be damaged by what we eat and drink and by not brushing.
Dentin
Underneath the enamel, you will find the dentin. This part is composed of tiny tunnel-like microscopic tubules and minerals. Even though it is made of minerals like enamel, this part is nine times softer than the outside shell. When your dentin is exposed, your tooth will become highly sensitive to chewing and hot and cold. This is due to the stimulation traveling through these tunnels.
Pulp
The center of your tooth, called the pulp, contains blood vessels and nerve tissue. Both dentin and enamel are known as hard tissues and are calcified. This means that the pulp is the only part of your tooth that is soft tissue. This part is significantly softer than the two outer layers and the softest part of the tooth.
Cementum
The cementum is the layer of tissue that connects the tooth’s roots to the jawbone and gums. When this is damaged, you will notice your tooth start to become more mobile. Keep it clean with proper flossing and mouthwash.
Gum Line
The gum line is where the tooth and gum meet and one of the most important areas to keep clean in your mouth. The actual meeting point of the tooth and gum line is called the tooth’s neck. It commonly collects bacteria and debris, making it a ripe breeding ground for plaque buildup as well as gingivitis and gum disease. Make sure to floss your teeth and use a proper mouth rinse can help keep your gums healthy.
Root
What you find below the gum line is the part of the tooth called the root. This part is not visible to the bare eye, but it does make up more than 60% of your tooth. The root’s outer layer is the cementum. It consists of hard connective tissue and connects the tooth to the periodontal ligament. This is the part responsible for keeping the tooth in its place in the jaw.
