Your mouth is a very busy place. Bacteria are constantly on the move on the tooth surface, gums, lips and tongue. You should know that although some bacteria are good for you, most of them are harmful. And harmful bacteria, if not removed in time, can cause dental cavities. In plain simple words, a cavity is just a hole or a hollow impression on the surface of your tooth.
The combination of bacteria and food particles are the primary cause of tooth decay. Certain types of bacteria get attached to hard surfaces like the enamel that covers your teeth forming a clear, sticky substance called plaque. If they're not removed, they multiply to form a colony. As this bacteria feed on the sugars in the food you eat, they generate harmful acids which attack the teeth after eating. Over time, these acids destroy tooth enamel, resulting in tooth decay also called, dental cavities or caries. Not having proper dental hygiene, frequent snacking and sugary drinks also make your teeth vulnerable to tooth decay.
Treatment for dental cavities is dependent on how bad its condition actually is. If the cavity is in a nascent stage, then your dentist may be able to reverse it by using fluoride. To fix cavities caused by mild tooth decay, your dentist will have to plug the cavities with another substance, popularly known as a filling. For severe tooth decay, you could need a crown or even a root canal treatment. In extreme cases, your dentist may have to remove the tooth altogether.
Untreated cavities can become larger and start affecting the deeper layers of your tooth. This can eventually lead to toothache, infection and in some severe cases, tooth loss. Creating and maintaining a good oral hygiene regimen is the best way to prevent cavities. But more than just developing this regime, it is also important for you to choose a toothpaste that has Flouride to prevent dental caries. After all, we sure go to great lengths to look and smell pretty - why not treat our teeth as well as we treat our bodies?
