Why fluoride is a crucial ingredient in many toothpastes and how does it play a significant role in oral health?

Fluoride helps in remineralisation of the teeth in the beginning stages of cavity formation, also result in fluorapatite formation which is naturally more resistant to attack by microbes. India doesnt have fluoridation of public drinking water.. so its better to get some in toothpastes atleast.

fluroide was long considered an important constituent of toothpaste as it forms a complex with the enamel (Hydroxyapatite) to make it resistant against acids and enzymes. Now however, newer compounds ( Xylitol, Nano-hydroxyapatite) are coming up and initial studies show they might even be better and more effective than fluoride

Fluoride is essential micro nutrient of many toothpastes. If added in excess or through excessive consumption even through diet can cause formation of “white patches” and it decreases the health of enamel. This is aesthetically very unpleasing and patch can be easily spotted as it is present on the surface of the teeth.
Hope it helps !:smiling_face:

Fluoride is essential to prevent tooth decay.
However , excess of fluoride leads to fluorosis- dental and skeletal.
In india there’s already an excess of Fluoride in drinking water, so question of supplementing it in water does not arise. In the US, areas where fluoride is less, municipalities tend to add Fluoride to drinking water.
Deficiency or excess of fluoride is bad -that is the bottom line

Fluoride works like a shield for our teeth, it strengthens enamel and prevents the acid produced by plaque bacteria from wearing it down.

Basically fluoride strengthens our enamel ( layer outside our teeth ) and protects teeth from harmful matter .

Fluoride is essential in toothpaste as it strengthens enamel, prevents cavities, and can reverse early decay. However, excessive use can cause dental or skeletal fluorosis, making it a double-edged sword-beneficial in proper amounts, but potentially harmful if overuse

India doesn’t have artificial fluoridation of water because it is already present in excessive amounts in the groundwater. Fluorosis is already a challenge India is facing. A study done in 2019 reports this data of concentration of fluoride in groundwater of India

In the present study, meta-analysis and meta-regression were performed on the F− concentration in groundwater of India and non-carcinogenic risk in the adults and children were estimated. The calculated pooled concentration of F− in groundwater of India was higher than the national and WHO standard limit. This study revealed that the concentration of F− in groundwater in rural areas is 1.85 times higher than urban region.

Fluoride is important as it

  • strengthens tooth enamel
  • prevents tooth decay
  • promotes remineralisation
  • reduces plaque bacteria

Fluoride is important in toothpaste because it helps strengthen your teeth and protect them from decay. When you brush, fluoride gets into the enamel—the hard outer layer—and makes it more resistant to acid attacks from bacteria and food. It also helps repair tiny early damage before it turns into cavities. Growing up, I didn’t think much about it, but once I started using fluoride toothpaste regularly, my dentist noticed fewer cavities, and I felt my teeth stayed stronger. It’s a simple thing, but it really makes a big difference in keeping your smile healthy.
