What chemical reaction happens when you brush your teeth?
Calcium phosphate and hydrogen ions undergo a reversible reaction with calcium ions, phosphoric acid and water. The products of the reaction are calcium ions, phosphoric acid and water. All of these exist in chemical equilibrium with the crystalline calcium phosphate.

What is the chemistry of toothpaste?
Toothpastes generally contain the following components: Water (20–40\%) Abrasives (50\%) including aluminum hydroxide, calcium hydrogen phosphates, calcium carbonate, silica and hydroxyapatite. Fluoride (usually 1450 ppm) mainly in the form of sodium fluoride.
What is the chemistry of tooth called?
This inorganic material is mainly composed by a calcium phosphate related to the hexagonal hydroxyapatite, whose chemical formula is Ca10(PO4)6·2(OH) 1.
Is milk sours a chemical change?
Complete answer: As milk begins to turn sour, the lactobacillus bacteria begin turning the lactose sugars found in the milk into a form of energy. Therefore milk souring is known as a chemical transition or chemical change because it ends up forming a new product that is the lactic acid, hence leaving the milk sour.
What chemicals are used in dentistry?
Some common chemical sterilants and disinfectants used in dental offices include glutaraldehyde, glutaraldehyde with phenol, hydrogen peroxide, hydrogen peroxide with peracetic acid, ortho-phthalalhyde (OPA), alcohols (ethyl, isopropyl), quatemary ammonium chloride, oxidizers (bleach), formaldehyde and phenolics.
