Squeeze you more every day, what is toothpaste made of? Everyone loves to eat and brush their teeth, but not everyone likes and wants to clean their teeth well. In addition to choosing a toothbrush that is pleasing to the eye, don’t forget to choose a toothpaste that is smooth to the mouth (?)

The toothpastes on the market are like cakes, with similar shapes, but the formula ratios are different. We have broken down the toothpaste into several main formulas, as follows When choosing toothpaste for the first time, try to find out which ones you understand! Abrasives (Abrasives) Judging from the history of human tooth cleaning, abrasive ingredients can be said to be the ancestors of tooth cleaning. In order to remove stains, you need something...well...something with a friction feeling, which was used by the ancient Egyptians. It is a mixture of burned eggshells and pumice. The ancient Romans used crushed bones, oyster shells, charcoal powder and bark. Even in the 18th century, Britain still used porcelain powder and brick powder, which sounded very hard. Element. Today, the abrasives we use to clean our teeth have been improved to be very gentle to avoid damaging our precious (and non-renewable) enamel. Currently, the more commonly used abrasives in toothpaste include silicon dioxide (SiO2), Aluminum oxide (Al2O3), calcium carbonate (CaCO?), dicalcium phosphate (CaHPO4), phosphate (PO43?), etc. These ingredients themselves have no cleaning function and must be paired with a toothbrush to help remove these fine particles from our teeth. of impurities and dirt.

Detergents (Detergents), as the name suggests, are ingredients with a cleaning effect (foaming), usually surfactants, which can help remove insoluble dirt such as grease and the like. For water stains, the most commonly used ingredient at present is sodium lauryl sulfate (also known as sodium lauryl sulfate, NaC ? H ? SO ?, which can be obtained from coconut oil or palm oil). Fluoride It is well known that teeth are afraid of acid, but as soon as you eat something (especially something containing sugar), the bacteria in your mouth will begin to decompose these residues and produce acidic substances. The fluoride ions in fluoride can interact with the receptors. It reacts with damaged teeth to produce calcium fluorophosphate (Ca10(PO4)6F2), which is more acid-resistant than enamel, thus helping to resist acid erosion.
