Causes of Acid attack!…

The first article of this series highlighted the role of acid and sugar in causing dental erosion. When teeth are exposed to high sugar and acidic foods for long periods, the saliva in our mouths cannot neutralise these acids. This will lead to tooth structure breaking down.

According to a survey 68% of Australian children between the ages of 6 and 15 showed at least one tooth with signs of dental erosion (Choice 2010).

The cause of dental erosion is usually linked to the types of foods we choose to consume and also the frequency in which they are consumed.

Most types of fruits are generally acidic, citrus fruits being more acidic than other types of fruit. However white grapes and red delicious apples are also quite acidic.

Even though fruits have sugar in their makeup the type of sugar found in fruit is not easily broken down by bacteria. As a result sugars in fruit are generally less harmful to teeth.

There are some types of beverages which are consumed frequently in our diets that are rather bad for the teeth. These include soft drinks, wine, some types of fruit juice and energy drinks, to name a few. Even drinks which have artificial sugar in them can be acidic. Like diet types of soft drinks, these may be low in ‘sugar’ but are still acidic due to their various preservative content.

When these beverages are consumed regularly and sipped over an extended period of time, the level of exposure of the acid and sugar will eventually lead to dental erosion.

Common types of foods like some cereal bars eg apricot muesli bars, confectionery like mixed jellies, chupa chups, tomato sauces and also honey can be high in sugar and acidic. Some may seem healthy but can be rather detrimental to teeth.

Basically, the more frequently you consume these foods, over a longer period, the higher the likelihood of tooth structure dissolving.
