Fluoridated toothpaste (toothpaste manufacture)

Fluoridated toothpaste is toothpaste that contains fluoride.Scientists have found that fluoride is effective in preventing tooth decay and increasing the ability of teeth to fight tooth decay.For children, especially children under 6 years of age, pay attention to preventing excessive fluoride intake due to poor swallowing reflex.

The use of fluoride ions in toothpaste is 1000 mg/kg, and numerous clinical trials show that tooth decay is reduced by approximately 20 – 30%.By adding 0.02% or 0.05% sodium fluoride to the rinse, dental caries can be reduced by 40%.Since the 1980s, the number of patients with dental caries has decreased significantly, which is closely related to the fluoridation of toothpaste.In addition to fluoridation of drinking water, good dental hygiene education and improved personal hygiene certainly also play a role.Adding fluoride to toothpaste reduces tooth decay is certain, but reliably assessing the best dose of fluoride in toothpaste is difficult.

Protection against caries

Bacteria that directly inhibit plaque: Fluoride has an inhibitory effect on acid-forming bacteria.It can inhibit the storage of polysaccharides in caries-causing streptococcal cells, affecting the growth and reproduction of bacteria;Caries Inhibitor Streptococcus synthesizes extracellular polysaccharides, reducing the adhesion of bacteria and bacterial stains to teeth.

2. Effect of fluoride on tooth enamel: The surface membrane is the basis on which bacteria attach to the tooth surface, and fluoride plays an important role in inhibiting the formation of the surface membrane and the growth of bacterial stains.The ion exchange of fluorine and hydroxyphosphate in enamel hydroxyphosphate, forming fluorophosphate, strengthens the enamel structure, reduces solubility and thereby increases resistance to caries.

3. Promote mineralization: Promote re-mineralization of demineralized tooth enamel at the onset of caries.
