What substance are teeth made from?

Answer 1

What tooth enamel is made of pretty much depends on who you ask. Some experts say, "Enamel's primary mineral is hydroxyapatite", to which I disagree because how could they know the enamel's composition if they can't even get the correct word usage right? Hydroxyapatite is the incorrect use of the word, "hydroxyL-apatite" (capital letter and hyphen used for clarification) but that is not what tooth enamel is made of either according to others who say, "tooth enamel is calcium hydroxy phosphate". Other so called experts [who claim that Fluoride (a corrosive toxic poison) is good for you] say that the tooth enamel's strength is "enhanced by the formation of fluoroapatite, a naturally occurring component of tooth enamel". This is also a lie because Fluoroapatite (more correctly spelled fluorapatite), is a natural calcium halophosphate or fluorinated calcium phosphate mineral that is mined from the earth for the making of phosphate fertilizer. Fluorine (used in some Freon) and Hydrofluosilicic acid (used to fluoridate drinking water and ther industrial applications) are both highly toxic and dangerous and are liberated from the natural mineral Fluorapatite. Fluorapatite is not a "naturally occurring component of tooth enamel". Still others argue that tooth enamel is, "calcium phosphate" (I agree) while other experts say enamel is, "composed of approximately 28% organic matter and 72% inorganic (calcium)", which is a vague but some-what true response although I have to plead ignorance on the actual percentages of calcium phosphate in the enamel. Everyone agrees that under the enamel is what's called, "dentin" but as for what the enamel is - well that depends on who your asking and whether or not they are trying to promote the fluoride myth. You see if they can get you to believe that your teeth "already contain naturally occurring fluoroapatite" (which they do not), then what's the harm in adding a little more fluoride to strengthen them? From the research and knowledge that I have come to find, my best answer is that tooth enamel is basically composed of calcium phosphate mineral but not hydroxylapatite.

Answer 2

tooth enamel is made up of 72% calcium and 28% organic matter. It is similar to egg shell, with the organic matter part, so it is good for science fair tooth experiments if you don't want to use real teeth.

Answer 3

Enamel, the whitish covering, is the hardest and most mineralized part of the teeth and of the entire body. About 96 percent of enamel consists of a mineral called hydroxylapatite, a form of which also makes up to 50 percent of bone.

The other 4 percent is water and organic material. Because of its high concentration of mineral power, enamel is strong enough to withstand the stress of biting, chewing and grinding. However, that same trait makes enamel brittle and susceptible to cracking and chipping.

Dentin, a yellow-hued substance, makes up most of the tooth. It is responsible for giving the tooth its color. Dentin, which is less mineralized and less brittle than enamel with 70 percent minerals (hydroxylapatite and calcium phosphate), 20 percent organic materials (primarily proteins) and 10 percent water acts as a support for enamel. Because dentin is softer, it is more prone to decay.

Cementum, a yellowish substance covering the root of a tooth, is even softer than the enamel and the dentin. Hydroxypatite is its main mineral, comprising about 45 percent of it. Proteins, mainly collagen (the most abundant protein in humans), make up 33 percent of the cementum, while water is left with the remaining 22 percent. The role of the cementum is to help anchor the tooth to the jawbone and ensure its stability.

Plup, as the "nerve" of the tooth, the pulp's major role is to form dentin through biological cells at its outer surface called odontoblasts. The pulp is composed of blood vessels and nerves. Among the cells that make up the pulp are white blood cells like macrophages and T lymphocytes.
