Fluoride Free Toothpaste. The main ingredient in this option is nano-hydroxyapatite, which helps re-mineralize teeth. Plus, this toothpaste also contains essential oils.
Fluoride has a high tendency to react with the calcium hydroxyapatite Ca10(PO4)6(OH)2 in tooth enamel due to its high affinity to metals. [8] [10] It subsequently replaces the hydroxide group in hydroxyapatite to precipitate calcium fluorapatite Ca5(PO4)3)F. [8] These fluorapatite precipitations scavenge excess phosphate and calcium in the saliva to form a supersaturated solution for ...
When fluoride ions are present in plaque fluid along with dissolved hydroxyapatite, and the pH is higher than 4.5, [16] a fluorapatite-like remineralised veneer is formed over the remaining surface of the enamel; this veneer is much more acid-resistant than the original hydroxyapatite, and is formed more quickly than ordinary remineralised ...
Fluoride therapy is the use of fluoride for medical purposes. [2] Fluoride supplements are recommended to prevent tooth decay in children older than six months in areas where the drinking water is low in fluoride. [3] It is typically used as a liquid, pill, or paste by mouth. [4] Fluoride has also been used to treat a number of bone diseases. [5]
Furthermore, nano-hydroxyapatite may have the capacity to reverse damage from carious assaults by either directly replacing deteriorated surface minerals or acting as a binding agent for lost ions. [27] In some toothpaste hydroxyapatite can be found in the form of nanocrystals (as these are easily dissolved).
Applying fluoride directly to the teeth through toothpaste or rinses is important, but Lochary said small amounts circulating in the body are critical for young kids who still have their baby teeth.
Sodium monofluorophosphate is produced industrially by the reaction of sodium fluoride with sodium metaphosphate: [2] NaPO 3 + NaF → Na 2 PO 3 F. The process involves scission of a pyrophosphate bond, analogous to hydrolysis. SMFP can also be prepared by treating tetrasodium pyrophosphate or disodium phosphate with hydrogen fluoride. [2]
The American Dental Association says adding fluoride to water streams is a "safe, beneficial, and cost-effective" public health measure, citing studies that it cuts cavities in children and adults ...
