Enamel is the white, mineral-rich protective outer layer of our teeth. It’s not just strong, it’s the hardest substance in our bodies. Surprisingly though, enamel can be weakened or softened just by the acids found in our everyday food and drink. If weakened, our enamel can then be more easily worn away, even during regular brushing. Over time, it can get gradually thinner, duller and see-through – eventually revealing the yellow layer underneath.
Normally, saliva helps neutralize acidity found in food and works to restore the natural balance of our mouths, while slowly re-hardening tooth enamel. Due to the acidity of our modern healthy diet, saliva doesn’t always neutralize acidity or re-harden tooth enamel fast enough.
Tooth Erosion can be described as the loss of tooth substance (i.e. enamel) and is different from Tooth Decay. It can be caused by either mechanical (e.g. grinding) or chemical (e.g. dietary acids) challenges. Tooth Erosion, also known as Acid Erosion, is the wearing away of enamel often due to dietary acids.
