Tooth decay often occurs when the acidity level of the mouth becomes too high, leading to demineralisation of the teeth. Simple carbohydrates (such as sugars) are considered to be a major culprit, as they are metabolised in the mouth by the bacteria in dental plaque. This in turn leads to a drop in pH level of the mouth and acid attack on the teeth.
The matter of sugars and tooth decay is not always a straightforward linear equation though. For instance, it can depend on various factors – such as the susceptibility of the individual to tooth decay, and on the timing and frequency of sugar intake.
Certainly it appears that some foods can increase the risk of decay, while others can actually slow it down or prevent it. In this post we take a look at both.
