Fluoride has become a complex subject. People fear fluoride may affect their intelligence or damage their health. This is untrue, and this explanation is meant to address the practical subject of fluoride in its entirety. There is “organic” fluoride, found in nature or made from only natural ingredients, and there is “synthetic” fluoride which is manufactured. The risk of problems from appropriate fluoride use of any sort are not just low, they are non-existent.
The relevant “organic” fluorides are stannous fluoride, or calcium fluoride. Stannous fluoride is superior to all fluorides keeping teeth cavity free, and is made from only natural components. The downside is stannous fluoride has tin and some worry about health effects from metal. Stannous fluoride can also stain teeth over time due to tin, and this is why it is less common. Interestingly, the tin component is also a reason stannous fluoride stops cavities so well, because metal is naturally antimicrobial. Calcium fluoride is the other “organic” fluoride, also made from natural ingredients, however it takes a long time to soak into a tooth, and thus far demonstrates inferior results stopping cavities. In some ways, it serves as a product appeasing fears and allowing users to “feel” as if they get the same impressive effect of fluoride.
The main “synthetic” fluorides are sodium fluoride and sodium monofluorophosphate. Sodium fluoride is the most common fluoride because it soaks into teeth the fastest, healing them the fastest. Sodium fluoride and sodium monofluorophosphate are basically made from combining fluoride with phosphate harvested while making fertilizer – which is concentrated minerals. In reality, phosphate is a mineral our teeth need to stay hard, and making “synthetic” fluoride from a mineral process makes sense, and also follows simple techniques: sodium fluoride is made by combining hydrofluoric acid with what is standard table salt. Hydrofluoric acid results from getting phosphate minerals out of rock. Hydrofluoric acid is abbreviated HF, table salt is abbreviated NaOH. The mixture is HF + NaOH, and the result is NaF + H2O, also known as sodium fluoride and water. The water is taken out, and sodium fluoride remains. Then we put it on our teeth and it fixes them, and we can swallow it and it will recirculate in our saliva, further healing teeth. Sodium fluoride can also strengthen our bones as a mineral. There is nothing else in that mixture, and as a result, there is nothing mysterious that can cause harm. Initial ingredients mixed to form new ingredients. There is no hydrofluoric acid or table salt going on your teeth or in your body. In fact, when you put sodium fluoride (NaF) back into water, it becomes sodium (Na+) and fluoride (F-).
In terms of the other “synthetic” fluoride, sodium monofluorophosphate, this is made by phosphate rock mixing with salt water to form sodium metaphosphate, which is then mixed with sodium fluoride, forming sodium monofluorophosphate. The names are simply taken from the process that makes them.
You can have peace of mind knowing all origins are traceable. If you do too much of anything it will harm you: drink too much water and it will leach minerals and electrodes from your body, eat too much calcium and it will effect the electrical activity in your heart, eat too much salt and your vessels will burst from water pressure, and if you eat too much fluoride it will stain developing adult teeth in kids or build up too much in the bodies of adults and replace other minerals. So that is why a dentist should be the person who determines how much you get.
That being said, it is very hard to consume too much fluoride. It requires eating tubes of toothpaste either at once, or chronically over years. Not using fluoride risks losing your teeth, a component of the mouth which actually is the first organ in the digestive system, and the source of your health. Poorly chewed food from few remaining teeth wreaks havoc on the digestive tract, and also affects our psychological state. Fluoride is imperative to continue remineralizing teeth, keeping them hard & decay resistant, and chronic mineral loss in teeth may not reveal damage until lots of teeth suddenly begin cavitating. And then it is too late – because putting minerals back in teeth takes much longer than plaque leeching them out.
The cavity problem happens all day to almost everyone, while fluoride damage is almost non-existent in competent hands. May this help alleviate the burden of understanding an otherwise very valuable component of our health and happiness.
