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 outdoors layer of the tooth, totally covers the dentin, and is really transparent in color. That implies the color of our teeth is because of dentin and not enamel. Nevertheless, enamel is comprised of enamel rods which can hold stain rather quickly, including red wine, coffee, tea, and cigarettes.
What is enamel comprised of?
Enamel is comprised of 96% calcium hydroxyapatite and 4% organic material and water. Bone is composed of 50% hydroxyapatite and 50% organic material including collagen, thus making enamel the hardest compound in the body.
If I chip or break enamel, will it repair on its own?
Sadly, enamel does not contain any living cells. If broken, it will not repair itself. Dentin can fix itself if damaged.
What is hydroxyapatite?
Hydroxyapatite is a storage type of calcium in the body. 99% of calcium in bone is saved as hydroxyapatite. The chemical formula for hydroxyapatite is Ca5(PO4)3OH.
What is dentin?
Dentin makes up the bulk of the tooth. It totally surrounds the pulp, and is covered by enamel on the crown portion of the tooth, and by cementum on the root of the tooth. Dentin is typically yellow in color and eventually identifies the color of the tooth, being that enamel is transparent. Dentin is made up of dentinal tubules that interact directly with the pulp. This means that is bacteria reaches the dentin, typically some type of pain will be felt. Dentin is made up of 65-70% calcium hydroxyapatite, 20-25% organic material, and 10% water.
What is cementum?
Cementum covers dentin on the root surface of the tooth. Cementum connects the tooth to the gum ligaments and is for that reason somewhat responsible for securing 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 income of the tooth. Pulp materials nutrients, blood, and nerves to the tooth. This implies that the pulp is responsible for keeping the cementum, dentin, and dentin strong.
Well what if my pulp is gotten rid of with a root canal?
Once bacteria reaches the pulp, depending upon how substantial, it's generally recommended to have the pulp eliminated. This is because the pulp communicates directly with the rest of the body, and if hazardous bacteria exists in your pulp, and it easily move to other locations of the body, consisting of the brain!! Please Get more information see the post on root canal for additional info on this subject.
That means the color of our teeth is due to dentin and not enamel. Enamel is made up of enamel rods which can hold stain quite easily, consisting of red wine, coffee, tea, and cigarettes.

Dentin is typically yellow in color and ultimately figures out the color of the tooth, being that enamel is transparent. Cementum covers dentin on the root surface area of the tooth.
