What is erosion?
Tooth erosion occurs when the teeth are exposed to acids, causing their surface layer to dissolve. These acids (which are present in fruit juices, soft drinks, and stomach acid reflux, etc) soften the enamel of the tooth causing it to gradually wear away. Unlike tooth decay, which might only occur in one tooth, tooth erosion affects all teeth. It is most commonly caused by the consumption of sugary drinks. Even some products marketed as health drinks can have extremely high acid content and will have adverse effects on teeth if consumed regularly. Teeth are most vulnerable immediately after consuming such drinks, as the enamel has been softened. For this reason, it is advisable to wait at least an hour before brushing your teeth.
Layers of tooth enamel begin to peel away like the layers of an onion, and this can slowly reduce the size of the teeth. This condition is painless and can sometimes go unnoticed until severe, irreversible damage had been done.
