What Are Teeth Made Of?
We all know what our teeth do, and why it is important to look after them, but what are they actually made of?
Enamel – this is the outermost layer of the crown of the tooth and is the hardest substance in the human body. It is our biggest protection from tooth decay so it is important to look after it as it is susceptible to acid erosion from foods and drink. It can also be fractured or chipped from eating hard foods or biting hard objects. The enamel does not regenerate, so if it is destroyed, your body will not make more to replace it.
Cementum – this is the outermost layer of the root of the tooth which helps to attach the teeth into the jawbone. The cementum that covers the root is not as strong as the enamel that covers the tooth crown, so it is important to keep the teeth and gums free of plaque to avoid gum recession.
Dentine – this is the layer located beneath the enamel and cementum and can become exposed if the enamel is lost due to trauma or erosion. It is hard but nowhere near as hard as enamel, so will wear away much faster. It is made of many tubes or ‘tubules’ which communicate with the nerve of the tooth. This means that if you have exposed some dentine, things such as hot and cold may become sensitive or painful.
Pulp – also referred to as the ‘nerve’ this is the living centre of the tooth which extends from inside the crown, down the length of the root and is made up of blood vessels and nerves. The nerves are helpful as they are sensitive to stimulation and can be a big indicator of a problem with the teeth. They are sensitive to hot and cold temperatures, and sweet or acidic foods.
