Sodium fluoride is a chemical that is found in our toothpaste, water, preservatives and pesticides1. The chemical may be commonly seen as Na-F. Na represents sodium, and F represents fluoride. Sodium fluoride is not as safe as it may seem. If a human swallows or inhales sodium fluoride, it can be poisonous to their health2. The chemical can cause skin and eye irritation2. It can also make a human vomit, become nauseated and create an upset stomach2. Sometimes the chemical can produce worse effects. If a human is exposed to sodium fluoride for a long time, the individual can become anaemic or suffer from brittle bones3.
          The most common place sodium fluoride is found in within our toothpaste and mouth washes. The chemical works to prevent cavities by fighting bacteria4. Some people find is scary that a chemical that can make you sick is an active ingredient in our toothpaste. If you’re scared of using toothpaste that contains sodium fluoride, there are fluoride free toothpastes that you can use as an alternative5.
          Another place that sodium fluoride is found is within pesticides and preservatives1. The chemical is known to be a great ingredient that can kill unwanted bugs and rodents1. Sodium fluoride is also keeps glue and pastes from going bad as it acts as a preservative1.
          Sodium fluoride can be also found in water naturally or as an additive6. The chemical is added in safe levels to water in order prevent tooth decay6. Recently many people feared that the negative effects of sodium fluoride outweighed the benefits. The fear created a motion in Calgary to remove the chemical from its drinking water7.
          I personally think that sodium fluoride is harmless in safe levels. I also think people are too quick to criticize before knowing all the facts. Sodium fluoride has been used for more than a century. Why are we suddenly fearing it now?
