Strictly speaking, the sugar itself does not harm the teeth. Lactic acid, which is produced when bacteria in the plaque eats the sugar is the real culprit here. The acid lowers the pH level in the oral cavity and dissolves minerals from the enamel. The coating can then no longer fulfill its function as a protective jacket.
In time, this process leads to caries and other pathogenic bacteria. The less sugar you consume, the lower the lactic acid production, and consequently, there’s less of a chance of tooth decay, resulting in an overall healthier oral cavity.
So, you may be wondering: What Causes Cavity?
Those of you who do not want to do without the sweet stuff altogether can still pay attention to their teeth. It makes sense to limit the consumption of those saccharine munchies to once a day and thus not constantly expose the teeth to sugar or lactic acid.
Furthermore, it’s good to wait for about half an hour after the consumption of something sweet before brushing your teeth. For a speedier freeing of the mouth from the lactic acid and the remaining saccharine coating rinse the mouth with some water.
