The tooth is made up of 4 layers, the enamel, dentin, cementum, and dental pulp.
What is enamel?
Enamel is the hardest compound in the entire body. It's the outdoors layer of the tooth, totally covers the dentin, and is really transparent in color. That indicates the color of our teeth is because of dentin and not enamel. Nevertheless, enamel is consisted of enamel rods which can hold stain rather easily, including red wine, coffee, tea, and cigarettes.
What is enamel consisted of?
Enamel is comprised of 96% calcium hydroxyapatite and 4% natural material and water. Bone is made up of 50% hydroxyapatite and 50% natural material including collagen, therefore making enamel the hardest compound in the body.
If I chip or break enamel, will it fix on its own?
Regrettably, enamel does not consist of any living cells. For that reason, if chipped, it will not fix itself. Dentin can fix itself if harmed.
What is hydroxyapatite?
Hydroxyapatite is a storage kind of calcium in the body. 99% of calcium in bone is kept as hydroxyapatite. The chemical formula for hydroxyapatite is Ca5(PO4)3OH.
What is dentin?
Dentin comprises the bulk of the tooth. It totally 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 usually yellow in color and eventually identifies the color of the tooth, being that enamel is transparent. Dentin is composed of dentinal tubules that communicate directly with the pulp. This suggests that is bacteria reaches the dentin, typically some type of discomfort will be felt. Dentin is composed of 65-70% calcium hydroxyapatite, 20-25% natural material, and 10% water.
What is cementum?
Cementum covers dentin on the root surface of the tooth. Cementum links the tooth to the periodontal ligaments and is therefore rather responsible for protecting the tooth in the bone. It is made up of 50% calcium hydroxyapatite and 50% natural product and water, the very same consistency as bone.
What is pulp?
Pulp is the livelihood of the tooth. Pulp products nutrients, blood, and nerves to the tooth. This means that the pulp is accountable for keeping the dentin, dentin, and cementum strong.
Well what if my pulp is eliminated with a root canal?
Once bacteria reaches the pulp, depending on how comprehensive, it's normally advised to have the pulp got rid of. This is because the pulp communicates straight with the remainder of the body, and if harmful bacteria exists in your pulp, and it quickly move to other dental pulp areas of the body, consisting of the brain!! Please see the short article on root canal for more details on this subject.
