So, in this article, let us see, what exactly is your dentist looking for when you go for your yearly routine appointments.


Often, our dentists say that not to eat chocolates and sugary substance in excess. Why? Cavities or dental caries, as they are named, are caused by bacteria and acids. The bacteria itself emanates acid, which causes the enamel of the teeth to dissolve. These bacteria which emanates the acid, mainly feeds themselves from carbohydrates, which are available in excess in sugary substances and chocolates. Not only chocolates and other carbohydrates, but also other acid containing beverages such as cold drinks, soda, vomiting and even acid reflux can enhance the chances of cavities. On the action of these acids, the enamel area of the teeth, starts becoming soft and then dissolves away. At some point of time, the hole becomes too big, and thus, it has to be filled.

Now, while you visit a dentist, they have several ways to check your teeth for cavities. They can take an x-ray of your mouth area, and then they may search for places where the density is less. They may also do a visual check, by giving air to the mouth, and check whether any of the teeth is turning in to a chalky color which is generally a symptom of cavities. Dentists also have access to instruments that will find holes in the teeth.
