The tooth is made up of 4 layers, the enamel, dentin, cementum, and dental pulp.
What is enamel?
Enamel is the hardest substance in the whole body. It's the outside layer of the tooth, totally covers the dentin, and is actually transparent in color. That implies the color of our teeth is due to dentin and not enamel. Nevertheless, enamel is comprised of enamel rods which can hold stain rather easily, consisting of red wine, coffee, tea, and cigarettes.
What is enamel comprised of?
Enamel is consisted of 96% calcium hydroxyapatite and 4% natural product and water. Bone is made up of 50% hydroxyapatite and 50% organic product consisting of collagen, thus making enamel the hardest substance in the body.
If I chip or break enamel, will it fix by itself?
Enamel does not contain any living cells. If chipped, it will not fix itself. Dentin can fix itself if damaged.
What is hydroxyapatite?
Hydroxyapatite is a storage form of calcium in the body. 99% of calcium in bone is stored as hydroxyapatite. The chemical formula for hydroxyapatite is Ca5(PO4)3OH.
What is dentin?
Dentin makes up the bulk of the tooth. It entirely surrounds the pulp, and is covered by enamel on the crown part of the tooth, and by cementum on the root of the tooth. Dentin is generally yellow in color and ultimately determines the color of the tooth, being that enamel is transparent. Dentin is made up of dentinal tubules that communicate straight with the pulp. This implies that is germs reaches the dentin, usually some type of discomfort will be felt. Dentin is made up of 65-70% calcium hydroxyapatite, 20-25% natural product, and 10% water.
What is cementum?
Cementum covers dentin on the root surface area of the tooth. Cementum links the tooth to the gum ligaments and is for that reason rather responsible for securing the tooth in the bone. It is made up of 50% calcium hydroxyapatite and 50% natural product and water, the same consistency as bone.
What is pulp?
Pulp is the livelihood of the tooth. Pulp supplies nutrients, blood, and nerves to the tooth. This suggests that the pulp is accountable for keeping the cementum, dentin, and dentin strong.
Well what if my pulp is eliminated with a root canal?
