Introduction
Cavities are one of the most common dental problems worldwide, affecting millions of people every year. They are caused by tooth decay, which happens when bacteria in your mouth produce acids that erode your tooth enamel. While cavities can be prevented with good oral hygiene, once they develop, the only way to address them is through a dental procedure known as cavity treatment. One of the most common treatments for cavities is the use of dental fillings.
Dental fillings are materials used by dentists to restore the structure and function of a tooth that has been damaged by decay. This procedure is crucial in preventing further damage to the tooth, alleviating pain, and restoring the tooth’s appearance and function. In this article, we’ll explore the different types of dental fillings, how the procedure works, and why fillings are an essential part of maintaining oral health.
Understanding Cavities: The Basics
Cavities, also known as dental caries or tooth decay, begin when harmful bacteria in the mouth create acids that dissolve the tooth’s outer protective layer, known as enamel. This erosion leads to small holes or “cavities” in the teeth. Over time, if left untreated, cavities can grow larger and affect the deeper layers of the tooth, potentially causing severe pain or infection.
The process of cavity formation typically starts with plaque build-up on the teeth. Plaque is a sticky film of bacteria that forms on teeth after eating or drinking, especially sugary foods. The bacteria in plaque feed on sugar, and in turn, produce acids that gradually wear down the enamel. If the plaque is not removed through regular brushing and flossing, cavities can develop.
Early-stage cavities may not show any noticeable symptoms, which is why it’s essential to have regular dental checkups. However, as cavities progress, you might experience tooth sensitivity, visible holes, or even pain when chewing or drinking.
