Egg Experiment

In spite of being the hardest substance in the body, our tooth enamel is very susceptible to many threats, including acid attacks. When the pH in the mouth drops below the so called “critical level” of 5.5 for too long, the enamel starts to demineralise, and this is how cavities begin to form. There are many simple things we can do to counteract this demineralisation, such as reducing sugar intake, brushing in the mornings and evenings, and using a fluoride containing toothpaste. Fluoride ions replace the Calcium ions in our enamel, changing the hydroxyapatite crystals to stronger, more resistant fluorapatite crystals and thus reducing the risk of caries. This simple experiment clearly shows these effects.
