Causes:
The bacteria in the mouth feed from food leftovers, especially sugar. In that process they create acids that are very damaging to the hard dental tissues. The first step of destruction happens on the tooth’s enamel made by the acids that bacteria produce. The process slowly continues, disintegrating the enamel in depth and at one point reaches the dentin. If the decay is not removed in time, it can reach the dental pulp and cause more serious problems. The most common surfaces affected by caries are the approximal surfaces and the occlusal ones. The main reason behind this is that there are larger plaque deposits there and patients can’t always provide perfect oral hygiene. Other factors aside from bacteria are sugars. Eating a lot of food that contains sugar is the worst thing you can do to your teeth. As mentioned these bacteria use sugar to create acids that harm the enamel and dentin. So patients that eat a lot of sweets and don’t brush their teeth as often or improperly have a high-risk of dental caries. Other causes include low salivary flow, congenital teeth disorders, smoking, alcoholism and other diseases.
