Once tooth enamel has been eroded, it cannot be restored, but it can be replaced by the use of a bond or an artificial crown covering. Weak enamel may be strengthened by the introduction of certain minerals, including calcium and phosphate. Tooth enamel is the hardest and most mineralized part of the body, according to the Colgate company.
One thing that may cause enamel erosion is excessive consumption of soft drinks. Most of these drinks have high levels of citric and phosphoric acids, which react with enamel and eventually cause erosion. Eating a diet that's rich in sugar and starch is also likely to enhance the loss of enamel, states WebMD.
Erosion may also occur when a person uses an old toothbrush or a brush with very hard bristles as this may cause friction on the enamel. A person who has attrition or a natural rubbing together of teeth may also experience enamel erosion. Other causes of enamel erosion include acid reflux disease, gastrointestinal complications, medications and dry mouth.
The best way to care for enamel is to ensure proper mouth hygiene. This means using recommended toothpastes and mouthwash whenever brushing the teeth. Avoiding acidic drinks and foods rich in sugar or starch is also prudent.
